exactly what should this code be doing?

i'm guessing you want to print a triangle of asterisks right?

Ooble · Nov 7th, 2004, 10:17 AM

Please put your code in [code] tags - I can't even read that. And indent it as well, if you wouldn't mind.

yeah ..... i tried to do it but cannot... i can only think of that part i ve post... can you me to complete the program...

Ooble · Nov 7th, 2004, 8:04 PM

I would do it like this:

(Toggle Plain Text)

for (int i = 1; i <= numlines; i++) {
  for (int j = 1; j <= (i * 2 - 1); j++) {
    cout << "*";
  }
  cout << endl;
}

Piece of piss.

You're going to have to input the number of lines you want it to print.

(Toggle Plain Text)

#include <stdio.h>

int main(void)
{
	int numlines;
	scanf("%d", &numlines);
	for (int i = 0; i<numlines; i++) 
	{
 if(i<=numlines/2)
 {
 	for (int j = 0; j < (i * 2 + 1); j++)
 	{
  printf("*");
 	}
 }
 else
 {
 	for(int j = 0; j<((numlines-i)*2-1); j++)
 	{
  printf("*");
 	}
 }
 printf("\n");
	}

	return 0;

  
}

I believe. Maybe I did something wrong.
