How Can I Customize the Output of My C Class Using Operator Overloading?

Customizing Output with Operator Overloading for C Classes

Consider a custom C class, myclass, that you've created. To enable the output of values like integers or floating-point numbers when using cout << x, where x is an instance of myclass, you can utilize operator overloading.

To overload the insertion operator, <<, for your class, follow these steps:

1. Declare a friend function within the myclass definition. This function will overload the << operator and take two arguments: an ostream reference and a reference to an instance of myclass.
2. Inside the friend function, modify the ostream reference to output the desired value from the myclass instance.

Here's an example that outputs an integer:

struct myclass {
    int i;
};

std::ostream &operator<<(std::ostream &os, myclass const &m) {
    return os << m.i;
}

int main() {
    myclass x(10);

    std::cout << x;
    return 0;
}

For float values, modify the output statement in the operator<< function accordingly. By implementing this overload, you'll be able to customize the output of your myclass instances as needed.
