The Interview Question Today#27(26-3-19)(Size of structure)

Question:

Write a c program to find the size of structure without using sizeof operator?

Solution:

C program:

#include<stdio.h>
struct  XYZ{
    int x;
    float y;
    char z;
};

int main(){
    int sz = (int) (((struct XYZ *)0) + 1);
    printf("Size of Struct= %d",sz);
    return 0;

}

Output:

Size of Struct= 12
