Thread: While loop question

This is just a portion of my code and I know everything else works properly, but I need the code to check and see if the user entered a valid input (either 'H', 'S', or 'C'). I want the program to loop until the user inputs a valid variable, but when the user initially puts in one of the variables the program just hangs. It works fine if the user enters an invalid answer (it loops until a valid answer is entered) but then hangs again. Any ideas? I'm thinking the while loop is the issue...how do I get it to work? Thanks.

Code:

while ( ( status = getchar() ) != 'H' || 'S' || 'C' )
{
   switch ( status )
   {
      case 'H':   
      case 'h':  
        break;

      case 'S':  
      case 's':  
        break;

     case 'C':   
     case 'c':    
        break;

     case '\n':  
     case '\t':   
     case ' ':   
        break;

     default: /* Catches all characters that are not valid entries */
        printf("Incorrect status value entered.\n");
        printf("Enter a valid status value [H for hourly, S for salaried staff, or C for contractor]:\n");
   }
}
