Advanced switch statement within while loop?

Question

I just started C++ but have some prior knowledge to other languages (vb awhile back unfortunately), but have an odd predicament. I disliked using so many IF statements and wanted to use switch/cases as it seemed cleaner, and I wanted to get in the practice.. But..

Lets say I have the following scenario (theorietical code):

while(1) {

  //Loop can be conditional or 1, I use it alot, for example in my game
  char something;
  std::cout << "Enter something\n -->";
  std::cin  >> something;

  //Switch to read "something"
  switch(something) {
    case 'a':
      cout << "You entered A, which is correct";
      break;
    case 'b':
      cout << "...";
      break;
  }
}

And that's my problem. Lets say I wanted to exit the WHILE loop, It'd require two break statements?

This obviously looks wrong:

case 'a':
  cout << "You entered A, which is correct";
  break;
  break;

So can I only do an IF statement on the 'a' to use break;? Am I missing something really simple?

This would solve a lot of my problems that I have right now.

Answer 1

I would refactor the check into another function.

bool is_correct_answer(char input)
{
    switch(input)
    {
    case 'a':
        cout << "You entered A, which is correct";
        return true;
    case 'b':
        cout << "...";
        return false;
    }
    return false;
}

int main()
{
    char input;
    do
    {
        std::cout << "Enter something\n -->";
        std::cin  >> input;
    } while (!is_correct_answer(input));
}
