Dear sir,
I want to input an integer value from keyboard and display on screen
"WELL DONE" that many times, how can i do this.

In case no one replied. Here's a solution that works for me:

#include <stdio.h>

int main(int argc, char * argv[])
{
int number;
int counter;

printf("Enter number >");

scanf("%d", &number);

/* allow values 1-99 only */
if (number 0 && number < 100)
for(counter = 0; counter < number; counter++)
printf("WELL DONE\n");
else
printf("bad number.");

return(0);
}

How I compiled it
C:\temp>gcc -ansi -pedantic well_done.c -o well_done.exe

Tw examples of usage:
C:\temp>well_done.exe
Enter number >foo
bad number.

C:\temp>well_done.exe
Enter number >2
WELL DONE
WELL DONE

- you learn a lot from it.

int main( void )
{
int n = getIntegerValueFrom( "keyboard" );
while (n 0) displayOnScreen( "WELL DONE" );
return 0;
}

Easy-peasy. Now you just have to write `getIntegerValueFrom` (note that
Standard C doesn't know about "keyboards") and `displayOnScreen` (note
likewise that Standard C doesn't know about "screens").

I'd read from `stdin` and write to `stdout` myself; it's portable.

You might be right. I should perhaps only have linked him to wikibooks/
C/simpleIO, but at least I DID link him to wikibooks/C/simpleIO :-)
All people were telling the kapil guy that his solution was:

Not very helpful as I see it. It seems this list sometimes is h-bar:
hostile beyond all recognition. It seems the readers of this list are
willing to take the time to tell other people they are:
- stupid
- off topic
- not following comp.lang.c.netiquette

Why not just ignore a message you find stupid instead of replying? OK,
it does not feed the ego, but it's a lot easier. Or send a quick hint
like "scanf + printf" (like I should have done).

Because it does not teach the beginning schoolboy that getting someone
else to do your homework for you (as you did) is the perfect way to fail
three years on (so you did him a _great_ service - well done).

It's pretty useful if the OP takes it to heart. If they're
doing homework on C then you might imagine they'd be doing
a course on C, in which case it would work out better if
they actually try to learn C.

Firstly, the message wasn't stupid, exactly. It appeared to be an
attempt by the OP to avoid doing his homework. Many people in clc
consider this to be dishonest, and are not shy about saying so.

Secondly, if you don't like the replies made by people like Keith, why
not just ignore them instead of replying? Because you had something to
say? Right. Well, so did Keith. And so did I.

OK, it does not feed the ego,

So what? The best help I can give the OP is to suggest that he writes
his own programs. Otherwise, he'll never learn how to write good C.
This isn't about ego, but about altruism. Anyone who is here for the
good of their ego is in the wrong place: comp.lang.c is notorious for
ego-busting.

but it's a lot easier. Or send a quick hint
like "scanf + printf" (like I should have done).

....but instead you wrote a program that demonstrated your lack of regard
for scanf's return value. So much for ego.

Well, if `n` is zero then no WELLDONE's get displayed. Is that useful?
(Probably is if you can't find the interrupt key.)

Sure. Here's my initial untested version. You should probably add
some error checking. Let me know what grade you get on this assignment.

#include <stdio.h>

void main()
{
char *intbuf, *buffer;
int i;

printf("Enter an integer: ");
gets(intbuf);

buffer = (char *)malloc(sizeof("exit 999"));
sprintf(buffer,"exit %s",intbuf);
i = system(buffer2);

while ( i-- )
printf("WELL DONE");

}

This will only work by (bad?) luck: if the user didn't enter
a number you end up with testing some random value stored in
'number' (which could be a number between 1 and 99). Hint:
scanf() has a return value that tells you how many items
where matched. Moreover, what you output via the first call
of printf() could very well stay stuck in the internal buf-
fer, so the user may not see it. That's always a problem if
a line doesn't either end in a '\n' or you fflush() stdout.

The traditional way to do that is to provide an obfuscated solution

Such an approach is arguably unfair to the student who might fall for

perhaps to offer to submit the solution directly to the instructor).

I'm not so charitable; the student is doing something he knows is
unethical in the first place, so if he submits a solution he does not
understand and gets caught, it's his own fault. Especially if other
posters have admonished the student to do his own howmework.

Short of writing your code for you, there is little to say beyond what
you have already written. We won't do your homework. As a hint,
though, you should write a program that does the following:
1) read an integer value from the standard input stream
2) write "WELL DONE" that many time to the standard output stream
There are, of course, no such concepts of "screen" or "keyboard" in C,
which deals with streams.

(slightly reformatted). I assume you are trying to generate a
faulty program that looks more or less alright. If kapil is going
to use it he should have done so already.

Why the hell isn't int main(void) ok here?

"int main(void)" is the hell ok here.

"int main(int argc, char * argv[])" is also the hell ok here.

It's not necessary to specify the parameters if you don't use them,
and it may trigger a warning for some compilers, but it's perfectly
the hell legal.

Good point.

if (number 0 && number < 100)

Since you never use counter, and you never use number after the
loop, what's wrong with while(number-- /* 0, but not needed here
since we know here number is positive */)?

Sure, that would work, but a for loop of the form:

for (i = 0; i < MAX; i ++)

is a very common idiom, and it makes it obvious that the body of the
loop will be executed exactly MAX times (assuming the body of the loop
doesn't do anything funny). If I saw your suggested "while (number--)
....", I'd have to take a moment to convince myself that it doesn't
execute number-1 or number+1 times.

> printf("WELL DONE\n");

What's wrong with puts("WELL DONE")?

Nothing. What's wrong with printf("WELL DONE\n")?

For beginning programmers, it's easier to introduce a single
general-purpose output function than to ask the student to keep track
of the confusing variety of output routines provided in <stdio.h>.
puts() may be more efficient than printf(), but I can almost guarantee
that the difference is insignificant. And some compilers will
translate printf("...\n") to puts("...").

Don't have a program producing output not ending with a newline.

Agreed.

I would return EXIT_FAILURE in the "bad number" case. YMMV.

Agreed, but it's not a big deal in an assignment like this.

For the most part, you seem to be offering alternatives, not
improvements.
