    Reference another class's data member...

    The cpp is attached, heres the problem.

    In function User_Info i take in the users name, age and sex. These are three member functions, a string, int and char. Each returns its according variable.

    In function Greet_User i want to call in these three. I thought maybe i couldn't because they are private, but public gives me the same error. I am new to classes so please be patient. Some of the other functions are incomplete but the program will run if u remove my problem so you can ignore them. Heres the cpp.

    Change parameters to

    Code:
    void Hello(User_Info &User_Info);

    now its three errors

    Code:
    --------------------Configuration: ChatBot - Win32 Debug--------------------
    Compiling...
    ChatBot.cpp
    C:\Program Files\Microsoft Visual Studio\MyProjects\ChatBot\ChatBot.cpp(117) : error C2660: 'Hello' : function does not take 0 parameters
    C:\Program Files\Microsoft Visual Studio\MyProjects\ChatBot\ChatBot.cpp(240) : error C2597: illegal reference to data member 'User_Info::name' in a static member function
    C:\Program Files\Microsoft Visual Studio\MyProjects\ChatBot\ChatBot.cpp(244) : error C2597: illegal reference to data member 'User_Info::age' in a static member function
    Error executing cl.exe.
    
    ChatBot.obj - 3 error(s), 0 warning(s)
    The first one is the call in main cuz its .hello(), what should the para's be? the same?

    the arguement should be the name of the object, and use ".", not "::" to access variables
