C - Find the size of structure

Question

I was asked this as interview question. Couldn\'t answer.

Write a C program to find size of structure without using the sizeof operator.

Answer 1

struct  ABC

{

int a;

float b;

char c;

};


void main()
{

struct ABC *ptr=(struct ABC *)0;

ptr++;

printf("Size of structure is: %d",*ptr);

}
