Struct Padding

Code

#include <stdio.h>

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

void print_offsets() {
    MyStruct pStr;
    char * p = (char *)&pStr;
    char * p1 = (char *)&pStr.a;
    char * p2 = (char *)&pStr.b;
    char * p3 = (char *)&pStr.c;

    printf("Offset of a: %d\n", p1 - p);
    printf("Offset of b: %d\n", p2 - p);
    printf("Offset of c: %d\n", p3 - p);
    printf("Size: %d\n", sizeof(pStr));
}

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