You will create a Menu Builder class (for menu applications), a Test Menu class (for Main), and a MenuBuilder.h for a total of three files as a demonstration of understanding, creating, and using classes.

Answer 1

The errors are mainly because of improper using of if-else blocks in switch statement.

Working Code:

File: main.cpp

#include "MenuBuilder.h"

int main()
{
    // declare variables
    MenuBuilder transaction;
    int choice = 0;
    while (choice != 7)
    {
        transaction.buildMenu();
        cin >> choice;
        transaction.processInput(choice);
    }
}

File: MenuBuilder.h

};

#endif // MENUBUILDER_H_INCLUDED
