Question

Write a C++ program to ask the user to enter the shape type: square, sphere or circle and the appropriate dimensions of the shape.. The program should output the following information about the shape:

a.for a square. it output the area and perimeter.

b. for a sphere, it outputs the area.

c. fir a circle, it outputs the volume.

if the user input anything else, your program should output: "the program does not recognize this shape". Use const whenever it is appropriate (use the nested if)

area of sphere is 4*PI*r^2

area of circle is Pi*r^2 (Pi=3.1416)

Answer 1

code

#include<iostream>
using namespace std;
const float pi=3.14;
int main()
{     
       string type;
    //Declare variables
       float r;int s,perimeter;
       double volume;
       double area;
       cout<<"Enter the shape type: ";
       getline (cin, type);
       if(type=="square"){
           cout<<"Enter Side : ";
    cin>>s;
    //nested if
    if(s>0){
    area = 4*s;
    perimeter = s*s;
    cout<<"Area of Square : "<<area<<endl;
    cout<<"Perimeter of Square : "<<perimeter;
    }
           
       }
       
       if(type=="sphere"){
    
       //Input radius
       cout<<"Input radius: "<<endl;
       cin>>r;
       //Volume of sphere = 4/3(πr3)
       volume=(4/3)*(pi*r*r*r);
       cout<<"Volume of sphere:"<<volume<<endl;
       //Area of sphere = πr2     
       area=pi*r*r;
       cout<<"Area of Circle: "<<area<<endl;
       }
       
       if(type=="circle"){
           cout<<"Enter radius : ";
           cin>>r;
           area = 3.14159*r*r;
        cout<<"area of circle is : "<<area;   
       }
       //remaining condition
       else{
           
           cout<<"The program does not recognize this shape.";
           
       }
       return 0;

      
}

//output:
