(C++) switch

Keywords enabling control over program flow, used in combanation with the case and default keywords.

include <iostream>


int main()
{
  const int diceThrow = std::rand()%6;
  switch(diceThrow)
  {
    case 0: std::cout << "You threw 1 and lost!" << std::endl; 
      break;
    case 5: std::cout << "You threw 6 and won!" << std::endl;
      break; 
    default: std::cout << "You threw something useless!" << std::endl; 
      break;
  }
}

If you have a class that uses a state-dependent switch-statement, use polymorphism instead [1].
