Struct Padding

Code

#include <stdio.h>

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

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

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