Question

Code should be written in C++

2. [11] You have been hired by Shapes Calculator Menu Maker to create a C++ console application that prompts the user with a menu and various options. Starting from Lab03, prompt the user for a char value that corresponds to one of the following menu options: a. Sphere=4*pi"radius3 (hint: use a constant value for pi=3.1415) b. Right Circular Cylinder- piradius*height c. Rectangular Parallelepiped length *width height d. Cone-*pi*radius2 height 3 x. Exit menu. Implement this menu using a switch. If the user enters a value other than a, b, c, d, or x let the default be an error message to the user and then terminate the program. Format the output for each option (a, b, c, or d) as follows: A message with the option the user has chosen; Output the values for the given volume equation in two columns and three to five rows, the first one reserved for column labels (i.e. label, value). Use constant values for column widths, NICURE 44 svitch statement everything left justified and use setprecision(...) function to format the real values to two decimal places. Take a screenshot of the output with a valid and invalid input.

Answer 1

Please find the code below::

#include <iostream>
#include <iomanip>
using namespace std;
const int WIDTH = 10;
const float PI = 3.14;
void printMenu(){
   cout<<"a. Sphere"<<endl;
   cout<<"b. Right Circular Cylinder"<<endl;
   cout<<"c. Rectangle Parallelepiped"<<endl;
   cout<<"d. Cone"<<endl;
   cout<<"x. Exit"<<endl;
   cout<<"Enter your choice : ";
}
int main(){
   char choice;
   double r,l,h,w,vol;
   printMenu();
   cin>>choice;
   cout << fixed << showpoint << setprecision(2);
   switch(choice){
   case 'a':
       cout<<"Enter radius : ";
       cin>>r;
       vol = 4.0/3*PI*r*r*r;
       cout << setw(WIDTH) << left << "Radius"<<r<<endl;
       cout << setw(WIDTH) << left << "Volume"<<vol<<endl;
       break;
   case 'b':
       cout<<"Enter radius : ";
       cin>>r;
       cout<<"Enter height : ";
       cin>>h;
       vol = PI*r*r*h;
       cout << setw(WIDTH) << left << "Radius"<<r<<endl;
       cout << setw(WIDTH) << left << "Height"<<h<<endl;
       cout << setw(WIDTH) << left << "Volume"<<vol<<endl;
       break;
   case 'c':
       cout<<"Enter length : ";
       cin>>l;
       cout<<"Enter Width : ";
       cin>>w;
       cout<<"Enter height : ";
       cin>>h;
       vol = l*w*h;
       cout << setw(WIDTH) << left << "Length"<<l<<endl;
       cout << setw(WIDTH) << left << "Width"<<w<<endl;
       cout << setw(WIDTH) << left << "Height"<<h<<endl;
       cout << setw(WIDTH) << left << "Volume"<<vol<<endl;
       break;
   case 'd':
       cout<<"Enter radius : ";
       cin>>r;
       cout<<"Enter height : ";
       cin>>h;
       vol = 1.0/3*PI*r*r*h;
       cout << setw(WIDTH) << left << "Radius"<<r<<endl;
       cout << setw(WIDTH) << left << "Height"<<h<<endl;
       cout << setw(WIDTH) << left << "Volume"<<vol<<endl;
       break;
   default:
       cout<<"Please enter correct option"<<endl;
       break;

   }

   return 0;
}

output:
