Bug in the Code

How to remove this bug from the code????

#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;

// Fixed. Doesn't move anymore.

for ( i = 1; i < = LAST; i++ ) { sum += i; }

/*-for-*/

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

return 0;

}
