Set a value by default constructor or other constructor

Hello,

I'm trying to learn c++ but there is something I can't figure out. How do I call this class in the first if statement to change the overflowValue?

Here is my code:

Thanks in advance!

You could create a mutator (member function that changes a value) and change it from inside the class....

So:
1
2
3
4
 
void counterClass::changeOverFlowValue( int newVal )
{
   overflowValue = newVal;
}


then call it on the class;

myInstanceclicker.changeOverFlowValue( newval );

Currently, counterClass::counterClass(overflowVal); doesn't do anything except instantiate a new class object and not assign anything with which to reference it...

Thanks for responding, I just saw that the assignment requires me to have two constructors, how would I do to make sure that I have two of them where on is the default and the other one changes the value of the overflow value?

Overload your constructor.
Same function signature, but a change in at least one of the parameters will overload that function.

In the overloaded constructor, take an argument that will be the overflow value and assign yours accordingly.
