Const member in class

Question

Hi everyone.
I have two constructors in my class :
- first has no parameters;
-second is initialising const variable;

And that lead to have an error like” my class provides no initialiser for const member”.

So I can’t create non const object and I don’t have an access to non const methods.

Thank you

Answer 1

Uninitialized constant member variables are not allowed. Therefore you need to make sure that you initialize your const member in every constructor that you write, even if it is just a default value like 0.
Otherwise there is a possibility that the first constructor with no parameters is called and the const member ends up not initialized.
Here is a rather similar problem:
