Struct Padding

Code

#include <stdio.h>

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

void print_offsets() {
    MyStruct data;
    
     size_t reg1=(size_t)((char*)&data.a - (char*)&data.a);
    size_t reg2=(size_t)((char*)&data.b - (char*)&data.a);
    size_t reg3=(size_t)((char*)&data.c - (char*)&data.a);

    printf("Offset of a: %zu\nOffset of b: %zu\nOffset of c: %zu\n",reg1,reg2,reg3);
    printf("Size: %zu\n",sizeof(MyStruct));
    
}

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