conversion from 'int' to non-scalar type 'Employee' requested

Question

#include <iostream>
using namespace std;

class Employee
{
    /*These are attributes of a Employee class*/
    
    public:
    string Name;
    string Company;
    int Age;
    
    /*This is a method of class*/
    
    void IntroduceYourself()
    {
        cout<<"Name - "<< Name << endl;
        cout<<"Company - "<< Company << endl;
        cout<<"Age - "<< Age << endl;
    }
    
    /*This is user-defined constructor of class*/
    
    Employee (string name, string company, int age)
    {
        Name = name;
        Company = company;
        Age = age;
    }
    
};

int main ()
{
    /*Creating 1st instance of Employee class*/
    
    Employee employee1 = ("Danish", "Amazon" , 22);
    employee1.IntroduceYourself();
    
    /*Creating 2nd instance of Employee class*/
    
    Employee employee2 = ("Aqib", "Accountancy" , 23);
    employee2.IntroduceYourself();
    
} 

Answer 1

The problem is that when writing ("Danish", "Amazon" , 22) you're using the built in comma operator whcih will evaluate the fist two operands and then discard them and the final result of the expression ("Danish", "Amazon" , 22) will be an int prvalue. But since there is no converting constructor in your class that takes an int, that final resulting int cannot be used to create employee1. Similarly, for employee2 also.

The correct way to create the instances would be as shown below:

int main ()
{
   
//-----------------------v-----------------------v---->use braces instead of parenthesis
    Employee employee1 = {"Danish", "Amazon" , 22};
    employee1.IntroduceYourself();
    
    
//-----------------------v--------------------------v---->use braces instead of parenthesis    
    Employee employee2 = {"Aqib", "Accountancy" , 23};
    employee2.IntroduceYourself();
    
}

Method 2

Use direct initialization.

int main ()
{
    //use direct initialization syntax
    Employee employee1("Danish", "Amazon" , 22);
    employee1.IntroduceYourself();
    
    //use direct initialization
    Employee employee2("Aqib", "Accountancy" , 23);
    employee2.IntroduceYourself();  
}
