Thread: can i ask what is wrong with this code? [LOOPS only]

whats wrong with this code?
when i enter 10 as N.... it displays 81
when i enter 6 as N... its displays 25

can someone please edit or explain?

thanks!

Code:

#include <stdio.h>

void display(int n);

int main(void)
{
	int n;

	clrscr();

	printf("\nThis program computes and displays\n");
	printf("the sum of the first N perfect squares.");
	printf("\n\nEnter the value of N:\t");
	scanf("%d", &n);

	display(n);
	getche();
	return 0;

}

void display(int n)
{
	int i;
	int j;
	int sum = 0;

	for(i = 0, j = 0; i < ( n - 1 ); i++, j++);
	{
		printf("%d +", ( j * j ));
		sum = sum + (j * j);
	}

	printf("\n\n%d", sum);
}

hmm... can u suggest something please?

In other words: Remove the semi colon. Set your loop to start at 1 and run until it equals n.

Also, since i and j are effectivly the same you should be able to remove one of the variables.

thanks mike...
i never reviewed the syntax since it compiled properly and was ran properly...
im polishing it now...

thanks a lot! =)
