Practice question of Constructor in OOPs (C++)

 #include <iostream>

#include <string>

using namespace std;

class User  {

private:

    int id; 

    string password;

    

public:

        string username;

        

        User(int id) {

            this->id = id; // current is being stored to parameter id (right side is parameter) and left side is an object.

        } 

        

        

        // getter

        string getPassword() {

            return password;

        }

        

        //setter 

        void setPassword(string password) {

            this-> password = password;

        }

};

int main() {

    // Object

    User user1(101);

    user1.username = "apnacollege";

    user1.setPassword("abcd"); // always getting this wrong

    // correct is user1.setPassword("abcd");

    // not user.setPassword = "abcd"; for strings , mistake noted for next time!

    

    

    cout << "username : " << user1.username << endl;

    cout << "password : " << user1.getPassword() << endl;

    return 0;
