Question

Write a program to display the area of a rectangle after accepting its length and width from the user by means of the following functions:
getLength – ask user to enter the length and return it as double
getWidth – ask user to enter the width and return it as double
getArea – pass width and length, compute area and return area
displayArea – pass area and display it in this function.

Expected Output:

(i)

Enter the length: 29

Enter the width: 34

Rectangle Data

--------------

Length: 29

Width: 34

Area: 986

(ii)

Enter the length: 5.98

Enter the width: 29.345

Rectangle Data

--------------

Length: 5.98

Width: 29.345

Area: 175.483

Answer 1

#include <iostream>

#include <iomanip>

using namespace std;

double getLength();

double getWidth();

double getArea(double l,double w);

void displayArea(double area);

int main()

{

double l,w,area;

l=getLength();

w=getWidth();

area=getArea(l,w);

cout<<"Rectangle Data"<<endl;

cout<<"--------------"<<endl;

cout<<"Length:"<<l<<endl;

cout<<"Width:"<<w<<endl;

displayArea(area);

return 0;

}

double getLength()

{

double len;

cout<<"Enter the length:";

cin>>len;

return len;

}

double getWidth()

{

double width;

cout<<"Enter the width:";

cin>>width;

return width;

}

double getArea(double l,double w)

{

return l*w;

}

void displayArea(double area)

{

cout<<"Area:"<<area<<endl;

}
