Struct Padding

Code

#include <stdio.h>

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

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



}

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