C+ + program that computes the area and perimeter of a specified shape

#include

#include

using namespace std;

void rectangle () / /Defining function for rectangle

{ int h, w;

cout << "Enter height: ";

//taking input

cin >> h;

cout << "Enter width: ";

cin >> w;

cout << "The perimeter of the rectangle is " <<2*h + 2*w << " and the area is " <
}

void triangle () / /Defining function for triangle

{ int s1, s2, s3, h, w;

cout << "Side 1: "; / /Taking input

cin >> s1;

cout << "Side 2: ";

cin >> s2;

cout << "Side 3: ";

cin >> s3;

cout << "Enter the height: ";

cin >> h;

cout << "Enter the base length: ";

cin >> w;

cout << "The perimeter of the triangle is " <
}

void circle () / /Defining Function for the circle

{

const double p=3.14;

int w;

cout << "Enter the radius: "; / /Taking input

cin >> w;

cout << "The perimeter of the circle is " << p*2*w << " and the area is " << p*w*w<< endl; / /printing output

}

int main () / /driver function

{

int s;

cout << "Enter the shape (1 for rectangle, 2 for triangle, 3 for circle) : ";

//Asking user for the shape

cin >> s;

switch (s) / /checking which shape it chooses

{

case 1:

rectangle (); / /If user type 1, then calling rectangle function

break;

case 2:

triangle (); / /If user type 2, then calling triangle function

break;

case 3:

circle (); / /If user type 3, then calling circle function

break;

default:

cout <<"Enter valid choice for shape"; / /If user type other than 1,2,3

}

return 0;

}

Output

Enter the shape (1 for rectangle, 2 for triangle, 3 for circle) : 1

Enter height:2

Enter width: 3

The perimeter of the rectangle is 10 and the area is 6
