Struct Padding

Code

#include <stdio.h>
#include <math.h>

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

void print_offsets() {
    MyStruct st;
    char *base = (char *)(&st);
    printf("Offset of a: %d\n", abs((int)(base - (char*)(&st.a))));
    printf("Offset of b: %d\n", abs((int)(base - (char*)(&st.b))));
    printf("Offset of c: %d\n", abs((int)(base - (char*)(&st.c))));
    printf("Size: %ld\n", sizeof(st));
}

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