Struct Padding

Code

#include <stdio.h>

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

void print_offsets() {
    MyStruct s;
    char *s_offset = (char *)&s;

    printf("Offset of a: %d\n", int( &(s.a) - s_offset) );
    printf("Offset of b: %d\n", int( (char*)&(s.b) - s_offset) );
    printf("Offset of c: %d\n", int( (char*)&(s.c) - s_offset) );
    printf("Size: %d\n", sizeof(s));
}

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