Switches

Can any one give an example of a switch?

Code:

---

int number;
cin>>number;
switch(number)
{
      case 1:    DoSomething();
                      break;

      case 2:  DoSomethingElse();

      case 666: DoEndOfWorld();
                      break;

      default: cout<<"Not Valid";
}

---

if number is 1 the DoSomething will be called. if number is 2 then DoSomethingElse will be called followed by DoEndOfWorld. if number is 666 then DoEndOfWorld is called. If number is anything else "not valid" gets printed.

I assume that you're talking about switch statements.

Code:

---

#include <iostream>

using std::cout;
using std::cin;

int main()
{
    int x;

    cout << "Enter a number from 1 - 5 : ";
    cin >> x;

    switch( x )
    {
          case 1:  cout << "\nYou are dumb!"; break;
          case 2:  cout << "\nYou are average!"; break;
          case 3:  cout << "\nYou are clever!"; break;
          case 4:  cout << "\nYou are very clever!"; break;
          case 5:  cout << "\nYou are a genius!"; break;
          default:  cout << "\nYou are really dumb!"; break;
    }

    return 0;
}

The keyword break must be included if you want to "break" out of the switch statement. If a number is entered that is not in the range 1-5, then the default statement is executed.
