How do I use consts in C++ classes?

In C++, you can use the const keyword to define constant member variables in a class. This means their values cannot be changed after initialization.

Can you give me an example of a class with a const member?

Sure! Here's a simple example:

class MyClass {
public:
    const int myConst;
    MyClass(int value) : myConst(value) {}
};

In this example, myConst is a constant member initialized through the constructor.

What happens if I try to change the value of myConst?

If you try to change the value of myConst after it's initialized, you'll get a compilation error because const members cannot be modified.

Are there any other uses for const in C++?

Yes, const can also be used with member functions to indicate that they do not modify the object, and with pointers to indicate that the data being pointed to cannot be changed.
