I HAVE SOME SERIOUS PROBLEM , HOW TO MAKE A PROGRAM IN C
Q1:
Write a program using malloc function. In which you take input from
user and allocate memory equal to square of this number. Which
multiply numbers and draw a table in the following format?

Hint: User enters 3 then program allocates equal to 9 integer
memories.

Output:1

Enter a single digit number:
2
The multiplication table of 2 is:
1 2
----------------
1| 1 2
2| 2 4

Output:2

Enter a single digit number:

These problems seem relatively well described. Is there something
you're having trouble understanding? At least start on these problems,
yourself. That way, when you run into trouble, you can ask specific
questions and get useful answers. I wouldn't count on anybody doing
your homework for you.

I HAVE SOME SERIOUS PROBLEM , HOW TO MAKE A PROGRAM IN C

First point - don't type in CAPITALS. It is taken as SHOUTING and is
impolite. Many people will choose to ignore your post, or killfile you
(ensure that they don't see anything your post again).

Second point - this newsgroup is not "comp.lang.c.do.my.homework". We
are not here to make up for your lack of attention in class, your
unwillingness to approach your teacher for assistance or your complete
incompetence. If you are learning, you have to make some effort
yourself - write some initial attempts at solving the problems set,
and then you can, politely, ask the group for assistance when you
encounter difficulties with what _you_ have written.

Q1:
Write a program using malloc function. In which you take input from
user and allocate memory equal to square of this number. Which
multiply numbers and draw a table in the following format?

Odd english in the question, but still it's fairly clear what is
required.

How would you get input from the user? (Hint: I'd recommend not using
scanf()).
How do you convert the input to a numeric?
How would you square the number?

Producing the output is trivial, surely. A loop to do the headings,
followed by a loop, with a nested loop for each row.

What have you tried? What problem did you encounter?

>
Hint: User enters 3 then program allocates equal to 9 integer
memories.

Output:1

Enter a single digit number:
2
The multiplication table of 2 is:
1 2
----------------
1| 1 2
2| 2 4

Output:2

Enter a single digit number:
4
The multiplication table of 4 is:
1 2 3 4
--------------------------------
1| 1 2 3 4
2| 2 4 6 8
3| 3 6 9 12
4| 4 8 12 16

Q:2
Write a macros in which swap two number without using 3rd variable and
then call
Macro in main function.

Hint: a=4, b=2 after swapping a=2, b=4.

This was recently discussed in the group - a Google search would find
the discussion. It may also be discussed in the FAQ (Frequently Asked
Questions) at c-faq.com - it's so completely pointless and irrelevant
a task to what I do, that I haven't looked. I seem to recall the trick
involves XOR and I also seem to recall that there are shortcomings to
it, but as I say, I haven't spent a lot of time or energy on looking
into it.

^^^^^^^^^
Unless you have your own private version of stdio.h, you should use the
standard header <stdio.h>.

int main()
{
int a,b;
printf("Enter values of a & b : ");
scanf("%d%d",&a,&b);
a=a+b; //if a=4,b=2 now a=a+b=6

// style comments in posted code is a bad idea. // style comments for

This is very, very bad.
1) Suppose a+b INT_MAX. What do you think your code will do?
2) The OP wrote "Write a macros in which swap two number without using
3rd variable". What makes you think all numbers are ints?
3) This is not a macro.

The worst thing, of course, is not your program but the inane question.
The correct answer is "don't do that; don't even try."

b=a-b; //now b=a-b=6-2=4
a=a-b;//now a=6-4=2
printf("After swapping\n a=%d \t b=%d",a,b);
return 0;
}

//table (allocate memory by yourself!)

That's fair. Leave something for him to do himself.

#include"stdio.h"

^^^^^^^^^
see above

void main()

^^^^
This is silly. main returns an int in a hosted environment. There has
never been a standard for C in which main was defined as returning void.

{
int j=1,k=1,l=1;
int a;
printf("Enter a single digit number: ");
scanf("%d",&a);

Quite apart from the highly vulnerable form of input, with no error
checking, the above needs a fflush(stdout); after the prompt. I/O on
stdin and stdout need not be synchronous.

Note that a is not checked for being a single-digit number.

printf("\nThe multiplication table of %d is:\n",a);
//formatting
for(l=1;l<=a;l++)
printf("\t%d",l);

^^
*Never* use '\t' in output designed to be read by humans. Display
devices can interpret '\t' is widely differing ways and you have no idea
when you are writing your program what '\t' will end up as on output.

printf("\n");
for(l=1;l<=8*a;l++)

^^
You pulled that '8' out of empty air. You have no reason to expect
that 8 is an appropriate choice.

printf("-");
printf("\n");
//result
while(j<=a){

Don't rely on the initialization at the top of the block here. The
for(;;) construct is a much better approach.

printf("%d|\t",k); //formatting

^^
'k' is a superfluous variable. There is no information associated
with k not already present in the variable 'j'.

for(int i=1;i<=a;i++)

^^^
This is illegal for pre-C99 compilers. For C99 compilers, it creates
a needless confusion by shadowing the already declared 'i' with block scope.

printf("%d\t",i*j);
printf("\n");k++;
j++;}
}

To the original poster: If you turn in "Umesh"'s code, you will get the
grade you deserve. You will not like it.

No, it is horrid. The OP poster asked about swapping two number [sic].
The '^' operator requires operands of an integer type. And that's not
all that's wrong with it. This question has been beaten to death
before. If you really are committed to the silly XOR trick, check the
FAQ and the newsgroup archives to find out why you shouldn't be. You
might also find out why, even when the silly XOR trick works, writing it
as a single statement is a bad idea.

Don't be so ridiculous. By your rationale then the numbers to be swapped
could be different types and thus unswappable. At times it pays to maybe
consider the context the questions are asked in and give a cautious
reply along the lines of ...

"assuming we are talking about unsigned integers then one way might be ...."

that's not all that's wrong with it. This question has been beaten to

Students who come here asking these type of questions are rarely in the

Oh please give it a break, Richard. While others on this NG
help out giving topical answers and telling people when they

answers all the time. Why don't you just do like others and

Martin, I note from your reply and from another in this thread that both
Umesh and Guru Jois have started dispensing idiotic C advice. I guess
it's time for them to come *out* of my killfile. Things have come to a
pretty pass when one actually feels obliged to unplonk people for being
even more stupid than normal.

I frequently do and have done so.

But the pollution level in this NG is second to none. There has
developed a policy of elitist competition between show offs and
wannabees. I find it faintly embarrassing as well as highly
distasteful. And it is getting worse.

There is a big difference between being a savager of nOObs and someone
who pleas for a bit of sanity.

Killfile me for all I care. I really don't mind.

I would also suggest you add posters whose net nanny to help ratio is
more than 1:1.

Didn't you hear? Usenet's gone all asynchronous.

Why is there the constant feeding frenzy.

What makes you think any one person who replies has seen any of the
other replies? Maybe you get to see them as they come in - maybe you
have a great newsfeed - but not everyone is that lucky.

Leave it alone to see if someone else replies or ignore it.

Why should we pay you the slightest bit of attention? I don't recall
seeing you giving any C help whatsoever, and if you do give any that
I've missed, it's completely swamped out by your constant whining. Give
it a rest, or balance it with some clueful help.

As you point out there is a "constant feeding ferenzy" so anyone with
any intelligence who looks around the NG before positing should know
not to post homework questions...

The problem is it has got a LOT worse over the last 2-3 years. It is
getting like spam.

They don't research either the problem or the NG they are posting to.
They are fair game on a quiet afternoon. If you don't like the way this
NG works go somewhere else.

The problem is it has got a LOT worse over the last 2-3 years. It is
getting like spam.

They don't research either the problem or the NG they are posting to.
They are fair game on a quiet afternoon. If you don't like the way this
NG works go somewhere else.

Why not create a NG comp.lang.c.homework? We can point the posters to
this newsgroups (and hopefully get rid of them) and maybe some of them
will post there directly, and people who like to show off can post
solutions in there. The best would be that those "students" start
helping each other out (I know, the chance of this happening are
almost NULL).

Others (who don't like these threads) can just ignore this group (or
link it to /dev/null).

Kind regards,

Please don't shout at us. (hint: a sentence in all capitals is considered

Seems you had a serious problem in the classroom, paying attention to your
teacher.

Is this a new record?

No

14 posts.
9 of them are discourteous warnings about posting style, homework and
things being off topic.

What has happened is we are getting far more posts of the "PLS DO MY
HOMEWORK URGENT" type.

The why dont "we" agree that only ONE reply is enough. Why is there the
constant feeding frenzy. Leave it alone to see if someone else replies
or ignore it.

Then please don't post. Leave it to the others.

I'm not sure that makes sense when I am suggesting people IGNORE posts
they deem unsuitable - they can leave the reply to people who might be
able to constructively help.

It is no joke reading a thread to find 9 pompous rejoinders and only one
reply of substance. The point about "asynchronous" is about as valid as
saying we all use 386s. Sure, for some it might be ... very, very few.

Also you will find that most of us regard anyone who ignores
netiquette and starts off inappropriately is fair game.

No, its not most. Its a loud minority. I see a lot of regulars who do
reply with pointers and suggestions despite the "shove off" replies from
the loud minority.

>
As you point out there is a "constant feeding ferenzy" so anyone with
any intelligence who looks around the NG before positing should know
not to post homework questions...

The problem is it has got a LOT worse over the last 2-3 years. It is

I would suggest it is just that - people pulling strings to see the
regulars dance.

>

No. Because this NG can help people regardless of the petty jobs worths
who patrol the corridoors. No other NG that I am aware of has the same
level of "feeding frenzy". I find it dispiriting and inappropriate that
skilled qualified people like yourselves should deem it appropriate
behaviour in a public help news group.

I know I'm not the first to mention this and am sure I wont be the last.

I am also equally sure that the loud minority are so full of themselves
that this plea is akin to trying to squeeze blood from a stone.

So are the rest of us and when no one else replies we do so that there
is at least one answer...

And am sick to death of reading repeated
"off topic"

That I agree with.

"no homework done here"

No that one needs to be put up in lights... In fact I think it is in the
FAQ's and I know my notes on a "model home work question" that has been
posted here several times made it onto a couple of FAQ's and the like.

If you trample over the rules of the club you will be treated
accordingly.

This is not an NG for homework. However people will try to help anyone
who has made an effort.

If any of the "homework" posters had even bothered to look at the NG
before posting would have discovered what not to do.

"wrong platform" "we dont help
people who dont speak english" etc etc etc - time, after time after
time. I await with glee the answer "then we dont need to help you go
somewhere else".

The vast majority on here only read/write English. There is nothing
wrong with posting in Spanish, latin German, French or American but it
will limit the number of people who can read, let alone understand the
question.

Such responses can be rather tiresome, it's true. Nevertheless, no OP is
well-served by a well-meaning but incompetent answer to an off-topic
question that, had it been posted in a newsgroup where it's topical,
would have stood a much better chance of being properly corrected by
the experts local to that group.

Sticks and stones.

I have also given help here
- just not recently and not necessarily from this account.

Really.

Although what that has to do with you I don't know.

No more than the responses of other contributors to this group has
anything whatsoever to do with you. If you retain the right to say what
you like, accord them the same privilege. If you want the right to
whine even when people ask you not to, that's fine, but don't expect
other people to pay attention to you when you don't pay any attention
to them.

Even assuming a lack of
posts, I fail to see what that has to do with polluting the threads

Rubbish. There are plenty of people here who know far more about C than
I do.

It strikes me that you in particular are more interested in
swamping the nOOb and proving how clever you are rather than actually

It's not easy to create a big eight newsgroup (for good reasons).
There's a lot of work involved, and a fairly good chance it would end
up voted down after all that. An alt group is easy, but would have
troubles getting carried.

It is extremely rude, completely incorrect, and improperly authoritarian
for you to call "discourteous" completely proper posts which request the
poster not to shout, point out that we don't do homework, and warning
that posts that are not topical will not be given serious consideration.

If insist on passing judgment on other's posts, do try to be at least
close to being right. Then we would know that while you might be a
self-righteous prick, at least you would correct.

Get used to it - its what keeps the group relatively clear of offtopic
and unanswerable or unconfirmable garbage.

If you really dislike seeing it, you can of course killfile all the
people who make the posts - be warned however that you'll find it gets
very very quiet in here.

even if he occasionally thlips up, I'm not going to take the hump too

No, it is horrid. The OP poster asked about swapping two number
[sic]. The '^' operator requires operands of an integer type. And

Don't be so ridiculous. By your rationale then the numbers to be swapped
could be different types and thus unswappable.

Is this Richard just incredibly stupid or is he a troll? The silly XOR
trick works only with integer operands. It is undefined on anything
else. To point that out says nothing at all about what numbers are
"swappable". To claim that "By your rationale then the numbers to be
swapped could be different types and thus unswappable" requires a high
level of dishonesty or a very low level of intelligence. If one
concedes that two doubles might be meaningfully swapped, then one must
concede that the silly XOR trick is not the right approach.

At times it pays to maybe
consider the context the questions are asked in and give a cautious
reply along the lines of ...

"assuming we are talking about unsigned integers then one way might be ...."

This has been tried in the past, many times, and found disastrous. If
offtopic posts aren't redirected, more and more and more are posted
till eventually there's only noise, and all the knowledgeable people

Take a look at his posting history. Either he's a deliberate troll,

doesn't know any better, despite the fact that he's been told
repeatedly that they're wrong, and why they're wrong, and how to

If you haven't been paying close attention (you're certainly not

They don't research either the problem or the NG they are posting to.
They are fair game on a quiet afternoon. If you don't like the way this
NG works go somewhere else.

Why not create a NG comp.lang.c.homework?

Because it wouldn't work. The people who write the DO MY HOMEWORK
posts aren't going to expend the effort required to find such a
newsgroup, even if it were created.

We can point the posters to
this newsgroups (and hopefully get rid of them) and maybe some of them
will post there directly, and people who like to show off can post
solutions in there. The best would be that those "students" start
helping each other out (I know, the chance of this happening are
almost NULL).

So students who *correctly* ask for help, by showing what they've
already done and asking specific questions about where it's going
wrong, can get incompetent help. I don't think that would be an
improvement.

>>I HAVE SOME SERIOUS PROBLEM , HOW TO MAKE A PROGRAM IN C

Please don't shout at us. (hint: a sentence in all capitals is
considered shouteing in usenet). Seems you had a serious
problem in the classroom, paying attention to your teacher.

Is this a new record?

14 posts.

9 of them are discourteous warnings about posting style, homework
and things being off topic.

I count 43 posts. All are about to be killed.
