Solution 2

The simplified version of the code

C#

public double Width 
{
     get 
     { 
          return pri_width; 
     }
     set 
     { 
          if(value < 0)
          {
                pri_width =  -value;
          }
          else
          {
                pri_width =  value;
          }
     }
  }

Read ternary operator to unserstadn original code.

if you dont understand properties:

C#

public double GetWidth
{
    
          return pri_width;
}

     public void setWidth(double value)
     {
          if(value < 0)
          {
                pri_width =  -value;
          }
          else
          {
                pri_width =  value;
          }
     }

Discaimer: solution provided by JF2015 is the best one. I am just explaining the original code.

Solution 1

This basically only allows setting a positive Width. Any negative number is converted to positive. The Abs() function would also achieve that.

This here does the same:

C#

public double Width
     {
        get { return pri_width; }
        set { pri_width = Math.Abs(value); }
     }
