The given code has AreaOfCircle and AreaOfRectangle functions to calculate the area for Circle and Rectangle respectively. The requirement is to remove different function names and have a single function Area() with below overloading:
Area() //with no default parameter
Area(double radius)//with one parameter for circle
Area (double l, double w);//with two paramete for rectangle
The requirement is to have NO DEFAULT PARAMETERS
#include <iostream>
using namespace std;
void PrintMenu();
double Area();//Area with no argument
double Area(double r);//area for circle with one argument
double Area(double w, double l);//area for Rectangle with two arguments
int main(){
double radius,length,width,side;
int option;
do {
//Call PrintMenu
PrintMenu();
cin>>option;
switch(option){
case 1: cout << "Enter radius";
cin >> radius;
cout << "Area of circle with radius 1 is : "<< Area()<<endl;
cout << "Area of circle with radius : "<< radius <<" is "<< Area(radius)<<endl;
break;
case 2: cout << "Enter length and width: ";

//cout << "Area of Rectangle with length=1 and width =1 "<< " is "<< Area()<<endl;
