How to write a default constructor in c++?

Question

So I know that after you write a constructor in a class the default constructor goes away, so you have to start initializing every object. However, is there a way to write a default constructor so that you don't have to do this?

Thanks.

Answer 1

Before C++11

class MyClass
{
public:
    MyClass(int x, int y) {}
    MyClass() {}
};

or in C++11

class MyClass
{
public:
    MyClass(int x, int y) {}
    MyClass() = default;
};

You can write as many constructors as you like, but avoid making your class confusing to use.
