    <p>I do not understand why this program is not working. I'm new to C++, switching after three years of Java. I thought the error messages in Java made no sense but the errors I've been getting in C++ have been just straight gibberish. This is one I can actually understand. </p> <p>Anyway so I have a program that has a Rectangle and Square Class. The square class inherits from the rectangle class. All my classes are all in different files.</p> <p>================================(main)</p> <pre><code>#include &lt;iostream&gt; #include "Rectangle.h" #include "Square.h" using namespace std; int main(){ Square sq; }//end main </code></pre> <p>================================(Rectangle.h)</p> <pre><code>#ifndef RECTANGLE_H #define RECTANGLE_H class Rectangle{ public: Rectangle (int, int); void setLength (int); void setWidth (int); int getLength (); int getWidth (); int getArea (); private: int length; int width; }; #endif // RECTANGLE_H </code></pre> <p>=================================(Rectangle.cpp)</p> <pre><code>#include &lt;iostream&gt; #include "Rectangle.h" #include "Square.h" using namespace std; Rectangle :: Rectangle (int len, int wid){ length = len; width = wid; }//end constructor void Rectangle :: setLength (int l){ length = l; }//end setLength void Rectangle :: setWidth (int w){ width = w; }//end setWidth int Rectangle :: getLength (){ return length; }//end getLength int Rectangle :: getWidth (){ return width; }//end getWidth int Rectangle :: getArea (){ return length * width; }//end getArea </code></pre> <p>========================================(Square.h)</p> <pre><code>#ifndef SQUARE_H #define SQUARE_H class Square : public Rectangle { public: Square(); }; #endif // SQUARE_H </code></pre> <p>====================================(Square.cpp)</p> <pre><code>#include &lt;iostream&gt; #include "Rectangle.h" #include "Square.h" using namespace std; Square :: Square { //super :: Square(4, 3); cout &lt;&lt; "This is bullshit"; }; </code></pre> <p>=======================================================</p>

    1. COC++ doesn't have a `super` keyword. It uses constructor initialization lists to initialize things (unless you count in-class member initialization, introduced in C++11).

    2. COIMPORTANT NOTE: You are using OOP wrong. You just demonstrated a variant of the circle-ellipse-problem: http://en.wikipedia.org/wiki/Circle-ellipse_problem

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.
