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.

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 use constructor overloading?

If you don't use constructor overloading, you can only create objects using a single constructor, limiting flexibility.

Are there any limitations to constructor overloading?

Yes, you cannot overload constructors based solely on return type, and all constructors must have unique parameter lists.
