Struct Padding

Code

#include <stdio.h>

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

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

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