Struct Padding

Code

#include <stdio.h>

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

void print_offsets() {
    MyStruct s;
    int off_a, off_b, off_c;
    off_a = (char *)&s.a - (char *)&s;
    off_b = (char *)&s.b - (char *)&s;
    off_c = (char *)&s.c - (char *)&s;
    printf("Offset of a: %d\n", off_a);
    printf("Offset of b: %d\n", off_b);
    printf("Offset of c: %d\n", off_c);
    printf("Size: %d\n", off_a+off_b+off_c);
    printf("Size a: %d\n")
}

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