Error c2556: 'void _ thiscall ...... Overloaded function differs only by return type fro

 

 

This error indicates that the overload function only has different return types, which is not allowed in C ++, so an error message is reported.

 

 

Actually, I didn't need to reload the function.

 

 

Class

{

 

Void func (void );

 

}

 

 

Class B

{

 

Friend A: func (void); // It should be friend void a: func (void );

 

}

 

Compiler lookup A: The Void func (void) found in the function is not exactly the same, so it is assumed that this function should be reloaded.

 

 

It can be seen that this void cannot be omitted at will, or an error may be reported.

 

 

There is also a bool

 

If bool

 

Define bool

 

An error will also be reported.
