Thread: Complicated riddle?

Code:

#include <stdio.h>

void swap(int *a, int *b)
{
	int temp = *a;
	*a = *b;
	*b = temp;
}

int main(void) 
{
  int executer[8] = {7, 5, 2, 0, 1, 6, 4, 3};
  int x, y, j;

  for(x = 0; x < 8; x++)
    for(y = 0; y < 7; y++)
      if(executer[y] > executer[y+1]) 
      	swap(&executer[y], &executer[y+1]);

	for(j = 0; j < 8; j++)
		printf("&#37;d\n", executer[j]);
  
  getchar();
  return 0;
}

This code works.
But why 7 and not 8?

Oh now I got it!
Thanks

BTW,
GIve me an example of a downto loop and a upto loop.

BTW 2,
This is a bubble sort, isn't it? why stupid-sort?

oh and then the last parameter is i--;
right?
