Hi,
Could anyone over here, write a program in C using only for loop to
print the following output
*
***
*****
*******
*********
***********
I tried but could only get one side of the triangle...
Quick reply is appreciated. Thanks, 16 50437
this is my code
#include<stdio. h>
int main()
{
int i,j,k;
for(i=1 ; i<=8 ; i++)
{
for (j=7 ; j>=1 ; j--)
printf(" ");
{for(k=1 ; k<=i ; k=k+1)
printf("*");
printf("\n");}
}
}
please help me in finding where I did wrong. Thanks,
Vishnu

You also need to print the apropriate amount of space characters before
you start printing stars. You do print stars, but it's always the same
number of stars. Also, your image shows stars like: 1 3 5 7... starting
from one using step 2. This program doesn't do that.
hiiii,
can u help in writing tha code
please send me tha code
it is very urgent to me i know i have to do spacing
but i can't maintaining tha loops for that
i am waiting 4 ur reply
thanx
vishnu
Here it is. Variable i represents the row and n is the key variable.
#include<stdio. h>
void PrintTriangle(i nt noOfMaxAsterix) ;
int main(void)
{
int noOfMaxAsterix = 11;
PrintTriangle(n oOfMaxAsterix);
return 0;
}
void PrintTriangle(i nt noOfMaxAsterix)
{
int n, i, j, k, l;
n = (noOfMaxAsterix - 1) / 2;
for (i = 0; i < n + 1; ++i) {
for (j = 0; j < n - i; ++j)
putchar(' ');
for (k = 0; k < 2 * i + 1; ++k)
putchar('*');
for (l = 0; l < n - i; ++l)
putchar(' ');
putchar('\n');
}
}

Give us your instructor's e-mail address so we can send the code to
him directly. I'm sure you wouldn't want to take credit for somebody
else's work.
Don't worry, we'll be sure to mention your name.

We must do something. This is something. Therefore, we must do this. void PrintTriangle(i nt noOfMaxAsterix) { int n, i, j, k, l; n = (noOfMaxAsterix - 1) / 2;
for (i = 0; i < n + 1; ++i) { for (j = 0; j < n - i; ++j) putchar(' '); for (k = 0; k < 2 * i + 1; ++k) putchar('*'); for (l = 0; l < n - i; ++l)
Do you really need j, k, l? You could've used only one. Also, do you
really need the last for, just to print spaces?
Since you gave him the code you should've also add some comments so if
he doesn't bother to study at least he has some understanding of what's
going on.
thanx friends
i am getting output spacing is also correct but new line printing is
not getting properly
main()
{
int i,j,k,l,n,ast;
n=(ast-1)/2;
for(i=0;i<n+1;+ +i)
{
for(j=0;j<n-i;++j)
printf(" ");
for(k=0;k<2*i+1 ;++k)
printf("*")
for(l=0;l<n-i;++l)
printf("\n");
}}

This is not a C question, and thus is off topic here.
But here's a hint
Assuming that the top line of the triangle is #1, and the next line down is
line #2, try to relate the number of stars in a line to the line number. Also,
try to relate the number of spaces before the first star to the line number.
You should be able to come up with two formula, one for stars and one for
spaces, that vary properly with line number.
Now, re-read the information on printf() format codes, paying particular
attention to the "field width" and "precision" specifiers. See if there is a
way to use the two formula from above to regulate your printf() output.
You should be able to reconstruct the triangle with /one/ for() loop and /one/
printf(), within certain limits of triangle size.

nelu yazdi: void PrintTriangle(i nt noOfMaxAsterix) { int n, i, j, k, l; n = (noOfMaxAsterix - 1) / 2;
for (i = 0; i < n + 1; ++i) { for (j = 0; j < n - i; ++j) putchar(' '); for (k = 0; k < 2 * i + 1; ++k) putchar('*'); for (l = 0; l < n - i; ++l) Do you really need j, k, l? You could've used only one. Also, do you really need the last for, just to print spaces?
Of course only one of j, k, l could be used however in order to
emphasize the usage of for loops and the algorithm, I used them. If I
were assigned to give an executable I would do it as you suggested. Since you gave him the code you should've also add some comments so if he doesn't bother to study at least he has some understanding of what's going on.
I gave him the code but I also wanted him to understand the logic. The
question has a good structure to make somebody learn loops hence I
inforced the reader to understand by tracing what is going on. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

Hello all,
I am still working on my calendar program, and I have decided that
the best way is for my vb program to write html tags into a file and
then to print the file from ie6. Everything is fine, the only thing that
I would like to do is to have my program print the html file
automatically. I saw the printdocument object, but I wanted to know,
firstly if it's possible, and secondly if I should use this object and how?

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
