how to fix a BUG

#include <stdio.h >
#define LAST 10
int main(){
int i, sum = 0;

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

And the developer fixes it this way

#include stdio.h;
#define LAST 10

int main()
{
int i, sum = 0;
/*

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