Basic example using Structure and Pointer in C++

This program defines a temp struct that has two members: f and i. It then creates an instance of this struct: t. In main(), a pointer ptr of type temp and t is created. The ptr is assigned the address of t using the address-of operator &ab;.

The program then prints the values of f and i using the pointer ptr and the dereference operator *. The dereference operator is used in combination with the dot operator . to access the members of the struct pointed to by ptr. Overall, this program is an example of how to define and use a pointer to a struct in C++. It creates an instance of the temp struct, creates a pointer to this struct, assigns the address of the struct to the pointer, and then uses the pointer to access and print the values of the struct members

Source Code

#include<iostream>
using namespace std;
struct temp
{
   float f=23.34f;
   int i=10;
};
int main()
{
   temp *ptr, t;
   ptr = &t;
   cout<<"F :"<<(*ptr).f<<endl;
   cout<<"I :"<<(*ptr).i<<endl;
   return 0;
}
