C++ Constructor Copy Constructor Question

Introduction

Write a program that defines a class called MyClass with arbitrary data fields.

Write a user-defined constructor with parameters that initializes data members.

Write a user- defined copy constructor which copies all the members.

Make one object of the class called o1 and initialize it with values.

Make another object of a class called o2 and initialize it with object o.

Print data for both objects.

You can use the following code structure. 

#include <iostream> 

int main() 
{ 
    //your code here
} 




#include <iostream> 

class MyClass 
{ 
private: 
    int x; 
    double d; 
public: 
    MyClass(int xx, double dd);    // user-provided constructor 
    MyClass(const MyClass& rhs);   // user-defined copy constructor 
    void printdata(); 
}; 

MyClass::MyClass(int xx, double dd) 
     : x{ xx }, d{ dd } 
{} 
MyClass::MyClass(const MyClass& rhs) 
     : x{ rhs.x }, d{ rhs.d } 
{} 

void MyClass::printdata() 
{ 
    std::cout << "X is: " << x << ", d is: " << d << '\n'; 
} 

int main() 
{ 
    MyClass o1{ 123, 456.789 }; // invokes a user-provided constructor 
    MyClass o2 = o1; // invokes a user-defined copy constructor 
    o1.printdata(); 
    o2.printdata(); 
}
