Question

#include<iostream>

using namespace std;

int area(int);

int area(int,int);

float area(float);

float area(float,float);

int main()

{

int a,length,b;

float radius,base,ht;

cout<<"enter one side of the square";

cin>>a;

cout<<"enter length and breadth the rectangle:";

cin>>length>>b;

cout<<"enter the radius of the circle:";

cin>>radius;

cout<<"enter the base and height of the triangle:";

cin>>base>>ht;

cout<<"Area of square = "<<area(a);

cout<<"\nArea of rectangle = "<<area(length,b);

cout<<"\nArea of circle = "<<area(radius);

cout<<"\nArea of triangle = "<<area(base,ht);

}

int area(int a)

{

return(a*a);

}

int area(int length,int b)

{

return(length*b);

}

float area(float radius)

{

return(3.14*radius*radius);

}

float area(float base,float ht)

{

return((base*ht)/2);

}

Output

Answer 1

SOLUTION TO THE ABOVE QUESTION

In this question, we will include a menu on the main method to ask the user the operation he/she wants to perform, finding the area of a circle, rectangle, triangle or a square. Based on the option the user enters he/she will be prompted for the necessary parameters and the area of that shape be displayed together with its properties.

SOLUTION CODE

#include<iostream>
using namespace std;
//Function prototypes implimenting function overloading
int area(int);
int area(int,int);
float area(float);
float area(float,float);
int main()
{
	//Menu for the program
	cout<<"Enter the shape you want to calculate area for:"<<endl;
	cout<<"1.Square"<<endl;
	cout<<"2.Rectangle"<<endl;
	cout<<"3.Circle"<<endl;
	cout<<"4.Triangle"<<endl;
	int option;
	cout<<"Enter your option: ";
	cin>>option;
	
	if(option==1)
	{
		int a;
		cout<<"Enter one side of the square: ";
        cin>>a;
        cout<<"Area of the square = "<<area(a);
	}
	else if(option==2)
	{
		int length,breadth;
		cout<<"Enter length of the Rectangle: ";
        cin>>length;
        cout<<"Enter breadth of the Rectangle: ";
        cin>>breadth;
        cout<<"\nArea of the rectangle = "<<area(length,breadth);
	}
	else if(option==3)
	{	float radius;
		cout<<"Enter the radius of the circle: ";
  		cin>>radius;
  		cout<<"\nArea of the circle = "<<area(radius);
	}
	else if(option == 4)
	{
		float base,height;
		cout<<"Enter the base of the triangle:";
		cin>>base;
		cout<<"Enter the height of the triangle:";
		cin>>height;
		cout<<"\nArea of the triangle = "<<area(base,height);
	}
	else
	{
		cout<<"You have entered an invalid option please try again"<<endl;
	}
