getter+setters "Properties problem"

Question

i got to write a console application..that prints out a square. Class square should contain two constructors and an instance property Side that has get and set accessors for private data. The first constructor is a default constructor that takes no arguments and another takes a side length as a value. I got to write a test application to test the square fuctions that i define.. Please help as i dont have any idea as how to solve this problem.. thanks in advance..

This workd perfectly fine.. and thanks very much for the explanation in the next thread as how u go about to construct it. I reckon i got the concept now..

w there were some things you did terribly wrong. So I will explain some errors for you to learn from. The Square class was just fine. You instantiated the Square wich all is good. BUT... You tried to assign the input from the console to the private member m_Side. Wich is not accessable from outside of the class. So I replaces m_Side for the Side property wich is public so we can use it's value. Then you tried to declare a int vlaue named S1... Wich was allready the identifier for the Square object. So that resulted in an error because the compiler don't know wich S1 is a square or an int. Then again you tried to access the private member m_Side. Wich isn't possible as we know. the last thing is the Console.WriteLine() wich is a function. A function cannot be assigned to. It only takes parameters. So Console.WriteLine happy should be Console.WriteLine(happy). Because the WriteLine function applies to a whole line of text it wasn't really the must obvious to use. So I replaced it with the Write() function wich writes a char or string and stays on that line untill you pass a newline 
 to it. I hope this helps you a little further with the learning process. I'm also some sort of beginner with C#. Having my first course this week :) So don't pound me if something isn't entirly correct :) Cheers

Just copy/paste this in your file. It has comments so you should understand it when you read it :) using System; namespace ConsoleApplication2 { public class Square { public int m_Side; // m_Side is a member variable with the value of side public Square() // Default Constructor { m_Side = 0; } public Square(int SideValue) // Constructor which takes side as argument { m_Side = SideValue; } public int Side { get { return m_Side; } set { if(value>0) m_Side = value; else m_Side = 0; } } } public class SquareTest { static void Main () { Console.WriteLine( Enter Side Value ); Square sq = new Square(); //construct the square sq.Side = Int32.Parse( Console.ReadLine()); //read the sides if ( sq.Side > 0) { for ( int y=0; y < sq.Side; y++) // direction = down { Console.Write(
); //begin a new line for ( int x=0; x != sq.Side; x++) //go till the square side { /* * if y or x equals to zero it means we have the * upper and left side of the square. * * when y = side-1 or x = side-1 then we got the * right and bottom side of the square. * * So this is a simplefied: * * if( (y==0) || (x==0) || (y==side) || (x==side) ) * { * Write(*); //write a star * }else{ * Write( ); //write a space * } */ System.Console.Write( (y == 0 || x == 0 || y == sq.Side-1 || x == sq.Side-1) ? *: ); } } } Console.ReadLine(); //stop for a minute so we can see the result. } } } Good luck :)

Hey I got to print out a square on a console. In which class Square should contain two constructors and an instance property Side that has a get and set accessors for private data. The first constructor that takes no arguments and another takes a side length as a value. Then define a test application to test the Square functions which are been defined. The way i am going through this problem is : using System; namespace ConsoleApplication2 { public class Square { public int m_Side; // m_Side is a member variable with the value of side public Square() // Default Constructor { m_Side = 0; } public Square(int SideValue) // Constructor which takes side as argument { m_Side = SideValue; } public int Side { get { return m_Side; } set { if(value>0) m_Side = value; else m_Side = 0; } } } } The test appliation i define is : using System; namespace ConsoleApplication2 { /// /// Summary description for SquareTest. /// public class SquareTest { static void Main () { Console.WriteLine( Enter Side Value ); Square S1= new Square(); S1.m_Side=Int32.Parse( Console.ReadLine()); if ( S1.m_Side>0) { for ( int S1=0; S1

Isn't it the Microsoft course 245 somthing? Just print to the screen the squere size and area (In numbers) As this is a console.
