Struct Padding

Code

#include <stdio.h>

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

void print_offsets() {
    MyStruct s1 = {'a', 1, 2};
    char *ptr = (char*)&s1; 
    printf("Offset of a: %d\n", ((char*)&s1.a - ptr));
    printf("Offset of b: %d\n", ((char*)&s1.b - ptr));
    printf("Offset of c: %d\n", ((char*)&s1.c - ptr));
    printf("Size: %d \n", sizeof(s1));
}

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