C plus plus program for overloading operator?

Answer 1

#include<iostream>

#include<string>

// a simple class

class my_class

{

private:

std::string m_caption;

public:

// default constructor

my_class (std::string caption): m_caption (caption) {}

// read-only accessor

const std::string& get_caption() const { return m_caption; }

};

// output stream insertion operator overload

std::ostream& operator<< (std::ostream& os, const my_class& obj)

{

os << obj.get_caption();

return os;

}

int main()

{

// call default constructor

my_class object1 ("This is the caption for object1");

// exercise output stream insertion operator overload

std::cout << object1 << std::endl;

}

Answer 2

The assignment operator. If you do not declare one in your class, the compiler generates one for you.
