Struct Padding

Code

#include <stdio.h>

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

void print_offsets() {
    MyStruct var;
    printf("Offset of a: 0\n");
    printf("Offset of b: %ld\n", ((char*)&var.b - &var.a));
    printf("Offset of c: %d\n", ((char*)&var.c - &var.a));
    printf("Size: %ld", sizeof(var));
}

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