Struct Padding

Code

#include <stdio.h>

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

void print_offsets() {
    MyStruct my_str;
    MyStruct *STR = &my_str;
    printf("Offset of a: %u\n", ((char *)&(STR->a) - (char *)STR));
    printf("Offset of b: %u\n", ((char *)&(STR->b) - (char *)STR));
    printf("Offset of c: %u\n", ((char *)&(STR->c) - (char *)STR));
    printf("Size: %zu", sizeof(my_str));
}

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