Struct Padding

Code

#include <stdio.h>
#include <cstdint>

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

void print_offsets() {
    MyStruct s;
    printf("Offset of a: %u\n", ((uint8_t *)&s - (uint8_t *)&s.a));
    printf("Offset of b: %u\n", ((uint8_t *)&s.b - (uint8_t *)&s));
    printf("Offset of c: %u\n", ((uint8_t *)&s.c - (uint8_t *)&s));
    printf("Size: %ld", sizeof(s));
}

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