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

Explanation:

struct  ABC{

    int a;

    float b;

    char c;

};

int main(){

    struct ABC *ptr=(struct ABC *)0;

    ptr++;

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

    return 0;

}

Example 2:

#include <stdio.h>
#include <conio.h>

struct  ABC{
    int a;
    char c;
};
void main(){
clrscr();
struct ABC*temp;
printf("%d",(char*)(temp+1)-(char*)temp);
getch();
}
