Struct Padding

Code

#include <stdio.h>

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

void print_offsets() {
    MyStruct s;
    printf("Offset of a: %d\n", (&(s.a) - (char *)&s) * 4);
    printf("Offset of b: %d\n", (&(s.b) - (int *)&(s.a)) * 4);
    printf("Offset of c: %d\n", (&(s.c) - (short *)&(s.b)) * 4);
    printf("Size: %d", sizeof(s));
}

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