4 PROCEDURES (TASKS)
4.1 switch
#include <iostream>
using namespace std;
int main ()
{
char FAN;
cout << "To turn on the fan by room,\nplease select button no "<<endl;
cout <<"======================================================";
cout << "\n\tSelected button = ";
cin >> FAN;
cout << "\n\tFAN ON = ";
switch (FAN)
{
case '1':
cout << " Room 1 "<<endl;
cout << " \n\tRoom 2,3,4,5 is off "<<endl;break;
case '2':
cout << " Room 2 "<<endl;
cout << " \n\tRoom 1,3,4,5 is off "<<endl;break;
case '3':
cout << " Room 3 "<<endl;
cout << " \n\tRoom 1,2,4,5 is off "<<endl;break;
case '4':
cout << " Room 4 "<<endl;
cout << " \n\tRoom 1,2,3,5 is off "<<endl;break;
default:
cout << " Room 5 "<<endl;
cout << " \n\tRoom 1,2,3,4 is off "<<endl;break;
