Struct Padding

Code

#include <stdio.h>

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

#define SIZEOF(a,b)  ((char *)&b-(char *)&a)

void print_offsets() {
    MyStruct var;
    printf("Offset of a: %d\n",SIZEOF(var.a,var.a));
    printf("Offset of b: %d\n",SIZEOF(var.a,var.b));
    printf("Offset of c: %d\n",SIZEOF(var.a,var.c));
    printf("Size: %d\n",sizeof(var));

}

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