Struct Padding

Code

#include <stdio.h>

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

void print_offsets() {
 MyStruct *s;
 unsigned long base_addr = (unsigned long)s;
 printf("Offset of a: %lu\n", (unsigned long)&(s->a) - base_addr);
 printf("Offset of b: %lu\n", (unsigned long)&(s->b) - base_addr);
 printf("Offset of c: %lu\n", (unsigned long)&(s->c) - base_addr);

 printf("Size: %d",sizeof(*s));
}

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