Yup,it worked,as far as i see,the problem was because in class character i used void newCharacter(); insted of void static newCharacter();,can you tell me why that STATIC keyword make the problem,why do i need to put it ? Where can i learn more about those keywords ? Thanks again

no problem

static keyword retains its value after the scope has been existed

Interesting, I was having trouble calling my constructor class within an if statement. It limited the scope I could call the functions. So if I just include the static keyword, it will give it file scope in main.cpp? So I would not have to worry weather I called it in a loop, or an if, i can still use its class methods right after I have constructed an instance?

Static has three meanings in C++

1) Retain the value of a variable within the scope it was declared.
The actual value is stored in a special memory section on the heap.
The value on the heap gets the value of the definition of the declared variable. But only once.
Any operations on the variable will be reflected on to the reserved space on the heap.
That's why a static variable never seems to go out of scope.

2) Make the variable only visible within the file scope (code unit)
It's sort of the same as anonymous namespaces in C++

3) Declare a method as static within a class.
Normally non static methods of a class are called by passing the pointer this of an instance to the method.
Static methods are called by appending the class name and ::
This is because static methods don't get a this pointer passed to them.
Therefore a static method can only access static data.

If you only want to have the user select a rank, then the method can be static.
However if in the method you want to assign attributes according to the rank, then the method has to be non static.
