} why PLG PLB call not?

CodePudding user response:

PLG. Name -- -- -- -- -- -- -- -- -- like this call private member is not enough, add the get function obtained private member

CodePudding user response:

Is not a friend function can be called directly

CodePudding user response:

The Girl in the class, a friend function name is different, more than a 'o' :

 friend void prdata (const Girl & amp; PLG, const Boy & amp; PLB); 
//friend void prodata (const Girl & amp; PLG, const Boy & amp; PLB);

CodePudding user response:

Void prdata (const Girl & amp; PLG, const Boy & amp; (PLB) prdata spelling wrong friend void prdata const Girl PLG, const Boy & amp; PLB);

CodePudding user response:

You are prodata written statement
