Add constructors to base class









    
using  System;

    double  pri_height;  //  private

                                              width  +  "  and  "  +  height);

class  Triangle  :  Shape  {  
    string  style;  //  private  
      
    public  Triangle(string  s,  double  w,  double  h)  :  base(w,  h)  {  
        style  =  s;    
    }  
  
    //  Return  area  of  triangle.  
    public  double  area()  {  
        return  width  *  height  /  2;  
    }  
  
    //  Display  a  triangle's  style.  
    public  void  showStyle()  {  
        Console.WriteLine("Triangle  is  "  +  style);  
    }  
}  
  
class  MainClass  {  
    public  static  void  Main()  {  
        Triangle  t1  =  new  Triangle("isosceles",  4.0,  4.0);  
        Triangle  t2  =  new  Triangle("right",  8.0,  12.0);  
  
        Console.WriteLine("Info  for  t1:  ");  
        t1.showStyle();  
        t1.showDim();  
        Console.WriteLine("Area  is  "  +  t1.area());  
  
        Console.WriteLine();  
  
        Console.WriteLine("Info  for  t2:  ");  
        t2.showStyle();  
        t2.showDim();  
        Console.WriteLine("Area  is  "  +  t2.area());  
    }  
}
    
   
  
   



Output

Info for t1:
Triangle is isosceles
Width and height are 4 and 4
Area is 8

Info for t2:
Triangle is right
Width and height are 8 and 12
Area is 48
