Problems with case 'p' || 'P': syntax within a switch statement in C++

Question

I\'ve used the switch statement the following way:

   switch (ch){
   case \'P\' || \'p\': 
        goto balance;
        break;

   case \'r\' || \'R\':
           


        

Answer 1

case 'P' || 'p': 
    ...

was meant to be:

case 'P':
case 'p':
    ...

Note that there is another (in this case more reasonable) approach you could use:

switch ( std::tolower(ch) ) {
case 'p': 
     ...
     break;
case 'r':
     ...
     break; 

default:
     ...
}

you'll just have to #include
