Question

what is the flowchart and the pseudo-code for this problem ?

Using C++ the following program should be modular

My exercise asks me to write a program (geometry.cpp) that displays the following menu:
Geometry Calculator:
1. Calculate the area of a circle
2. calculate the area of a rectangular
3. calculate the area of a triangle
4. quit

Enter your choice (1-4)

-if the user enters 1, then the program should ask for the radius of the circle and then should display the area. use 3.14159 for PI.
- if the user enters 2, then the program should ask for the width and length of the rectangle and then should display the area.
- if the user enter 3, then the program should ask for the length of the triangle base and its height and then should display the area.
- if the user enters 4, then the program should quit.

Explanation / Answer

#include<iostream.h>
#include<conio.h>
class a
{
public:
   float area;
   void cir()
   {
       int r;
       cout<<"Enter radius";
       cin >> r;

       area=3.14159*r*r;

       cout<<"Area of circle is "<<area;
   }

   void rect()
   {
       int w, l;
      
       cout<<"Enter Width and Length";
       cin>>w>>l;

       area=w*l;

       cout<<"Area of Rectangle is"<<area;
   }
  
   void tri()
   {
          
       int h, b;
      
       cout<<"Enter Base and Height";
       cin>>b>>h;

       area=0.5*b*h ;

       cout<<"Area of Triangle is"<<area;
   }
};

void main()
{
   a o;
   int ans;
  
   cout<<"1. Calculate the area of a circle";
   cout<<" 2. calculate the area of a rectangular";
   cout<<" 3. calculate the area of a triangle";
   cout<<" 4. quit";

   cout<<" Enter your choice (1-4)";
   cin>>ans;

   switch (ans)
   {
       case 1:
           o.cir();
           break;
       case 2:
           o.rect();
           break;
       case 3:
           o.tri();
           break;
       case 4:
           return;
           break;
       default:
           cout<<"Enter number between 1-4 only";
           break;
   }
}
