Struct Padding

Code

#include <stdio.h>

typedef struct {
    char a;
    int b;
    short c;
} MyStruct;

void print_offsets() {
    MyStruct s;
    printf("Offset of a: %ld\n", ((char*)&s.a-(char*)&s));
    printf("Offset of b: %ld\n", ((char*)&s.b-(char*)&s));
    printf("Offset of c: %ld\n", ((char*)&s.c-(char*)&s));
    printf("Size: %ld\n", ((char*)&s.a-(char*)&s)+((char*)&s.b-(char*)&s)+((char*)&s.c-(char*)&s));
}

int main() {
    print_offsets();
    return 0;
}
