Answer to Question #260732 in C++ for comscie

Question

Write a program that will display a menu for the user to select what computation

to use. And compute the required outputs for each option. (see below the sample

menu). Use functions for this program.

M EN U

A] Compute area and circumference of Circle

B] Compute area and perimeter of a Rectangle

C] Compute Surface area and volume of a Cylinder

D] exit

Answer 1

#include<iostream>
using namespace std;
int main()
{
	char option;
	cout<<"Select an option: "<<endl;
	cout<<"A] Compute area and circumference of Circle\nB] Compute area and perimeter of a Rectangle\nC] Compute Surface area and volume of a Cylinder\nD] exit\n";
    cin>>option;
    if(option=='A'||option=='a'){
    	int r;
    	double Area,circumference;
    	cout<<"Enter the radius: ";
    	cin>>r;
    	Area=3.142*r*r;
    	circumference=3.142*2*r;
    	cout<<"Area is: "<<Area<<endl;
    	cout<<"circumference: "<<circumference<<endl;	
	}
	else if(option=='B' ||option=='b'){
		int l,w,perimeter;
		double Area;
		cout<<"Enter the length and the width of the rectangle: "<<endl;
		cin>>l>>w;
		Area=l*w;
		perimeter=2*(l+w);
		cout<<"Area is: "<<Area<<endl;
		cout<<"Perimeter is: "<<perimeter<<endl;
	}
	else if(option=='C'||option=='c'){
		int r,h;
		double Area,volume;
		
		cout<<"Enter the radius and heigth: "<<endl;
		cin>>r>>h;
		Area=(2*3.142*r*h)+(2*3.142*r*r);
		volume=3.142*r*r;
		cout<<"Area is: "<<Area<<endl;
		cout<<"Volume is: "<<volume;
	}
	else{
