Struct Padding

Code

#include <stdio.h>

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

void print_offsets() {
    MyStruct str1;
    printf("Offset of a: %u\n", (char *)&str1.a - (char *)&str1);
    printf("Offset of b: %u\n", (char *)&str1.b - (char *)&str1);
    printf("Offset of c: %u\n", (char *)&str1.c - (char *)&str1);
    printf("Size: %lu", sizeof(MyStruct));
}

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