Struct Padding

Code

#include <stdio.h>

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

void print_offsets() {
    MyStruct s;
    printf("Offset of a: %u\n",(char*)&(s.a)-(char*)&(s.a));
    printf("Offset of b: %u\n",(char*)&(s.b)-(char*)&(s.a));
    printf("Offset of c: %u\n",(char*)&(s.c)-(char*)&(s.a));
    printf("Size: %u",sizeof(MyStruct));
 
}

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