Struct Padding

Code

#include <stdio.h>
#include <cstddef>
typedef struct {
    char a;
    int b;
    short c;
} MyStruct;

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

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