Hello all,
Got a small problem I'm trying to figure out an obscure error (to me). What I'm trying to do is implement error handling with a loop count within a while statement for two sets of Menus in my Hangman game. Perhaps you all can lend me hand in discovering where the problem lies?
I understand that each .cpp file has it's own loop declaration and initiation and this is the problem but how would I initiate error handling the way I want to without getting these errors:
Error 1 - error LNK2005: "int loop" (?loop@@3HA) already defined in HangmanMenu.obj
Error 2 - fatal error LNK1169: one or more multiply defined symbols found 1

{
while (selection_new != 'X') //As long as user does not choose QUIT, run the MenuInput loop
{
MenuInput();
}
}
void Menu::MenuInput()
{
print();
SetInput(); //Again, this function would basically consist of cin >> selection;
DetermineMenuInput();
}
void Menu::print()
{
system ("cls"); //Clears the screen before displaying the menu
cout << endl << endl << endl;
cout << " Main Menu" << endl << endl;
cout << " A - Play" << endl;
cout << " X - Exit\n" << endl << endl;
cout << " Please enter your choice: ";
}
char Menu::SetInput() //Equates to a cin statement
{
cin >> selection_new;
selection_new = toupper(selection_new);
return selection_new;
}
void Menu::DetermineMenuInput() //Determine user's menu selection
{

}I can post each respective header file, if needed.
Thanks for any advice or direction in advance.
