Question

Write a switch/case program to calculate 1. Area of a rectangle=L*B 2. Perimeter of a rectangle=2(L+B)​

Answer 1

#include<iostream.h>

void main ()

{

int L,B,area, perimeter,choice;

cout<<"enter length";

cin>>L;

cout<<"enter breadth";

cin>>B

cout<<"enter choice: 1. area 2.perimeter";

cin>>choice;

switch (choice);

{

case 1:

area = L*B;

cout<<"area of rectangle="<<area;

break;

case 2:

perimeter=2*(L+B);

cout<<"perimeter of rectangle="<<perimeter;

break;

}

}
