case is a keyword to state which values to switch on. If there is no named value to switch on, default can be used optionally.


#include <cassert>

#include <iostream>

 

int main()

{

  const int coin = std::rand() % 2;

  switch (coin)

  {

    case 0: std::cout << "Heads" << std::endl; break;

    case 1: std::cout << "Tail" << std::endl; break;

    default: assert(!"Should not get here");

  }

}
