    <p>Here is the issue with my code</p> <p>I got a parent class <code>Shape</code> and a child class <code>Square</code></p> <pre><code>struct Point { int x,y; }; class Shape { private: string name; public: void setName(string); string getName(); virtual void setVerticlePoint() { }; virtual Point getVerticlePoint(); }; </code></pre> <p>Below is Square.cpp</p> <pre><code>class Square: public Shape { private: Point verticlePoint[4]; public: int noOfVerticles() const { return 5; } void setVerticlePoint(); Point getVerticlePoint(); }; void Square::setVerticlePoint() { int xData,yData; for(int i=0; i&lt;4; i++) { cout &lt;&lt; "Please enter x-ordinate of pt." &lt;&lt; i &lt;&lt; " :"; cin &gt; xData; cout &lt;&lt; "Please enter y-ordinate of pt." &lt;&lt; i &lt;&lt; " :"; cin &gt;&gt; yData; verticlePoint[i]-&gt;x = xData; verticlePoint[i]-&gt;y = yData; } } </code></pre> <p>So at main.cpp , i did this</p> <pre><code>int main() { Shape *point[5]; Point vertic`lePoint; Square *cro = new Square(); // some codes in between // now i prompt for verticle point shape[0] = squr; //assuming myShape &amp; myType is some string value shape[0]-&gt;setName(myShape); shape[0].setType(myType); //here i will be prompt to key in 4 times of X &amp; y Ordinate of the verticle point shape[0]-&gt;setVerticlePoint(); //Now the issue is i need to retrieve back my verticle point that i store in shape[0]. //here no issue cout &lt;&lt; "Get Name: " &lt;&lt; shape[0]-&gt;getName() &lt;&lt; endl; cout &lt;&lt; "Get Data:" &lt;&lt; shape[0]-&gt;getType() &lt;&lt; endl; //the top 2 works //this is the issue verticlePoint = shape[0]-&gt;getVerticlePoint(); cout &lt;&lt; sizeof(verticlePoint); //it output as size 8 , no matter which shape i use, i got other shapes with different verticle point. return 0; } </code></pre> <p>Issue is :</p> <p>How do i retrieve the <code>verticlePoint[array]</code> (e.g for square is <code>verticlePoint[4]</code>, how do i retrieve the Point into a variable in main class, and then use a for loop to call out the <code>x,y</code> of <code>shape[0]</code> for <code>verticlePoint[0]</code> to <code>verticlePoint[4]</code></p> <p>Thanks for all help!</p>

    1. CO"verticle" is not a word. "vertical" means an up-and-down orientation or position. But I suspect you really mean "vertex", meaning a corner or node (plural "vertices").

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.
