Convert Class to Another Class Type in C++

In this tutorial, we will be discussing a program to understand how to convert a class to another class type in C/C++.

Class conversion can be done with the help of operator overloading. This allows data of one class type to be assigned to the object of another class type.

Example

 Live Demo

#include <bits/stdc++.h>
using namespace std;
//type to which it will be converted
class Class_type_one {
   string a = "TutorialsPoint";
   public:
      string get_string(){
         return (a);
   }
   void display(){
      cout << a << endl;
   }
};
//class to be converted
class Class_type_two {
   string b;
   public:
   void operator=(Class_type_one a){
      b = a.get_string();
   }
   void display(){
      cout << b << endl;
   }
};
int main(){
   //type one
   Class_type_one a;
   //type two
   Class_type_two b;
   //type conversion
   b = a;
   a.display();
   b.display();
   return 0;
}
