Struct Padding

Code

#include <stdio.h>

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

void print_offsets() {
    MyStruct s;
    int offset_b = (char*)&s.b - (char*)&s;
    int offset_c = (char*)&s.c - (char*)&s;

    printf("Offset of a: %lu\n",0);
    printf("Offset of b: %lu\n",offset_b);
    printf("Offset of c: %lu\n",offset_c);
    printf("Size: %lu\n",sizeof(MyStruct));
}

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