Struct Padding

Code

#include <stdio.h>

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

void print_offsets() {
    
    MyStruct tmp;

    printf("Offset of a: %u\n", (unsigned long)(&tmp.a)-(unsigned long)(&tmp) );
    printf("Offset of b: %u\n", (unsigned long)(&tmp.b)-(unsigned long)(&tmp) );
    printf("Offset of c: %u\n", (unsigned long)(&tmp.c)-(unsigned long)(&tmp) );
    printf("Size: %u\n",sizeof(tmp));
}

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