Struct Padding

Code

#include <stdio.h>
#include <stddef.h>

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

void print_offsets() {
    MyStruct s;
    
    printf("Offset of a: %lu\n", (char *)&(s.a) - (char *)&s);
    printf("Offset of b: %lu\n", (char *)&(s.b) - (char *)&s);
    printf("Offset of c: %lu\n", (char *)&(s.c) - (char *)&s);

    printf("Size: %d\n", sizeof(MyStruct));
}

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