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
#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;
}

Use DevC++ to implement a program uses objected oriented programming to calculate the area of a rectangle. The program should create a Rectangle class that has the following attributes and member functions: Attributes: width and length Member functions: setWidth(), setLength(), getWidth() , getLength(), getArea() Where width and length are the respect width and length of a Rectangle class. The setWidth() and setLength() member function should set the length and width, the getWidth(), getLenght(), and getArea() member function should get the...

Use Java program Material Covered : Loops & Methods Question 1: Write a program to calculate rectangle area. Some requirements: 1. User Scanner to collect user input for length & width 2. The formula is area = length * width 3. You must implement methods getLength, getWidth, getArea and displayData ▪ getLength – This method should ask the user to enter the rectangle’s length and then return that value as a double ▪ getWidth – This method should ask the...

share your program enhance your work after submitting export to repl Due: Oct 12, 2020 05:00 pm submit : back to classroom run Instructions from your teacher: #include <iostream> Complete this program. using namespace std; When the program is complete it should ask the user to enter a rectangle's length and width, then display the rectangle's area. The program calls the following functions which need to be completed: double getLength() { // Add code here } double getWidth() { //...
In the code (C++) below, if you input 2 as length and 4 as width, the output is: Enter the rectangle's length: 2 Enter the rectangle's width: 4 Length: 2 | Width: 4 | Area: 8 | Perimeter:12 We worked on this code during class, but there were some things that I did not understand. 1) how does compiler read"l" as length, "w" as width, etc.? I thought you had to update it first, like "w=width." 2) i thought you...
Construct a C++ class named Rectangle that has floating-point data members named length and width. The class should have a zero-argument constructor that initializes each data member to 0. It should have member functions named calcPerimeter() and calcArea() that calculate the perimeter and area of a rectangle respectively, a member function setLength() and setWidth() to set the length and width, member functions getLength() and getWidth() to return the length and width, and a member function showData() that displays the rectangle’s length,...
Hello I have a question. I would like to check if the code follows this requirement. Rectangle.h - A complete Rectangle Class including both declaration and definition appRectangle,cpp separate in two different files the class definition and implementation Code: rectangle.h // Rectangle class declaration. class Rectangle { private: double width; double length; public: void setWidth(double); void setLength(double); double getWidth() const; double getLength() const; double getArea() const; }; //************************************************** // setWidth assigns a value to the width member. * //************************************************** void...

What is the width? "; cin >> rectWidth; cout << "What is the length? "; cin >>...
Create a Java Project in Eclipse with the following: Include the Rectangle class supplied below. Override the toString method for Rectangle. Override the equals method for Rectangle. Implement the comparable Interface for Rectangle (Compare by area) Rectangle class: public class Rectangle { private double length; private double width; public Rectangle(double l, double w) { length = l; width = w; } public double getLength() { ...
