    <p>So, let's say I have a project. This projects uses two classes. First class MenuClass and a second is Pentagon Class.</p> <p>Say I get inputs in Menu class, and I want to move or copy, whatever you say, to Pentagon Class.</p> <p>How do you do that? Here's a piece of code form my MenuClass:</p> <pre><code> Menu::Menu( void ) { userMenuSelection = Quit; } // Constructor Menu // ===================== Menu::~Menu( void ) { cout &lt;&lt; "====================================" &lt;&lt; endl; } // Destructor ~Menu // ===================== // ============================== // Accessor Member-Function Get() // ========================== MenuChoices Menu::Get( ) { return userMenuSelection; } // Accessor Method Get // ======================== // ============================= // Mutator Member-Function Set() // ======================================== void Menu::Set( MenuChoices newValue ) { userMenuSelection = newValue; } // Mutator Method Set // ======================= // ========================== // Member-Function Display( ) // ========================== void Menu::Display( ) { cout &lt;&lt; "======================================" &lt;&lt; endl; cout &lt;&lt; " MENU SELECTION " &lt;&lt; endl; cout &lt;&lt; "======================================" &lt;&lt; endl; cout &lt;&lt; "1: Calculate the Perimeter of Pentagon" &lt;&lt; endl; cout &lt;&lt; "2: Calculate the Area of Pentagon" &lt;&lt; endl; cout &lt;&lt; "3: Quit" &lt;&lt; endl; cout &lt;&lt; "======================================" &lt;&lt; endl; cout &lt;&lt; endl; } // Member-Function Display // ============================ // ========================= // Member-Function QueryUser // ========================= void Menu::QueryUser( ) { int selection; cout &lt;&lt; "Enter Menu Selection: "; cin &gt;&gt; selection; switch (selection){ case 1: userMenuSelection = Perimeter; break; case 2: userMenuSelection = Area; break; case 3: userMenuSelection = Quit; default: userMenuSelection = Quit; } // switch // =========== cout &lt;&lt; endl; } // Method QueryUser() // ======================= // ================= // Method Continue() // ======================== bool Menu::Continue( ) { return userMenuSelection != Quit; } // Method Continue // ==================== // ============================== // Member-Function ProcessCommand // ============================== void Menu::ProcessCommand( ) { int numberA; // Length of Sides if (userMenuSelection == Quit ){ cout &lt;&lt; "Thank you for using this type of program. Have a nice day!" &lt;&lt; endl; } else if (userMenuSelection != Quit) { cout &lt;&lt; "Please enter an integer value for the length of the sides: "; cin &gt;&gt; numberA; </code></pre> <p>So whenever I move/copy these input to Pentagon class I want it to do, for example something like this:</p> <pre><code> void Pentagon::ProcessCommand( ) { int numberA; // Length of Sides if (userMenuSelection == Quit ){ cout &lt;&lt; "Thank you for using this type of program. Have a nice day!" &lt;&lt; endl; } else if (userMenuSelection != Quit) { cout &lt;&lt; "Please enter an integer value for the length of the sides: "; cin &gt;&gt; numberA; // ============================== switch ( userMenuSelection ) { case Perimeter: cout &lt;&lt; "Perimeter = " &lt;&lt; (5 * numberA) &lt;&lt; endl; break; case Area: cout &lt;&lt; "Area = " &lt;&lt; numberA * numberA * sqrt(25.0 + 10.0 * sqrt(5.0)) / 4.0; break; default: cout &lt;&lt; "Warning: error state encountered." &lt;&lt; endl; } cout &lt;&lt; endl; } } </code></pre> <p>And then output this areas and stuff in main();</p> <p>Any ideas? Thank you!</p>

    1. COYou could make userMenuSelection a public static member. Then you could access it with Menu::userMenuSelection but then you can only have one instance of Menu.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
