What is constructor delegation in C++?

Can you explain what constructor delegation is in C++?

Constructor delegation in C++ allows one constructor to call another constructor in the same class, promoting code reuse.

Can you give me an example of constructor delegation?

Sure! Here's a simple example:

class MyClass {
public:
    MyClass(int x) : value(x) {}
    MyClass() : MyClass(10) {} // Delegating to the first constructor
private:
    int value;
};

In this example, the default constructor delegates to the parameterized constructor.

What are the benefits of using constructor delegation?

The benefits include reduced code duplication, easier maintenance, and improved readability of your code.

Are there any limitations to constructor delegation?

Yes, constructor delegation can lead to increased complexity if overused, and it may also introduce subtle bugs if not managed carefully.
