Jumping from one case to the default case in switch statement

Question

switch(ch){
          case \'a\':
                 //do something, condition does not match so go to default case
                 //don\'t break in here, and don\'t         


        

Answer 1

Refactor your code:

int test_char(char ch)
{
  switch(ch) {
    case 'a': if (condition) return 0; break;
    case 'b': // ...
    default: return -1;
  }

  return 1;
}

... 
// defaults processing switch
switch(test_char(ch)) {
  case 0: break; // condition met
  case 1: // default processing
  default: // case not handled by test_char
}

This also adds the benefit of being flexible to test for multiple classes of default processing. Say you have a group of chars [c, d, e, f] which share some common logic. Simply return 2 from test_char() for these cases (possibly after some conditions has been tested), and add a case 2: handler to the default processing switch statement.
