Class scope of the program section

If the definition of Class Member is outside the class body, the member names from the definition start to the end of the definition all belong to the class scope, but the return type of the front edge does not belong to the class scope. For example:

Typedef int type;
Type initval ();

Class Exercise
{
Public:
Typedef double type;
Type setval (type );
Type initval () {return 0 ;};
PRIVATE:
Int val;
};

Type/* The type here is the int */exercise: setval (type parm) defined in the global table/error: Prototype for 'Type exercise: setval (double) 'Does not match any in class 'exception'

{// Candidate is: Double exercise: setval (double) |
Val = parm + initval ();

}

You can also change the definition type to exerci: type, or modify the type declared by the member in the class to: type.
