What is constructor overloading in C++?

What is constructor overloading in C++?

Constructor overloading in C++ allows a class to have multiple constructors with different parameters, enabling flexibility.

Can you give me an example of constructor overloading?

Sure! Here's a simple example:

class Box {
public:
    Box() { /* default constructor */ }
    Box(int length, int width) { /* parameterized constructor */ }
};

What happens if I don't provide a constructor?

If no constructor is provided, C++ automatically generates a default constructor that initializes members to default values.

Are there any limitations to constructor overloading?

Yes, constructors must differ in the number or type of parameters. You cannot overload them solely by return type.
