Code between #ifdef NAME and #endif is only compiled when NAME is defined.

Solution explanation

Conditional compilation is used for debug logging and platform-specific code.

Show solution

#include <stdio.h>
#define VERBOSE

int main() {
    int n, x, sum = 0;
    scanf("%d", &n);
    for (int i = 0; i < n; i++) {
        scanf("%d", &x);
#ifdef VERBOSE
        printf("adding %d\n", x);
#endif
        sum += x;
    }
    printf("%d\n", sum);
    return 0;
}
