         case '/' :
         case '*' :
              return '4';
              break;                                            
         case '+' :
         case '-' :
              return '3';
              break;

With no default case, if one of the items supplied does not match, no value will be returned. Also, you have specified an integer return value, yet you are returning a char...is that your intent?

Oops stupid me. So there must be a default for switch. Arghz!!!!!

CODE


int prior(char ch)
{
    switch(ch)
    {
         case '/' :
         case '*' :
              return 4;
              break;                                            
         case '+' :
         case '-' :
              return 3;
              break;
         default:
              return 0;
    }
}



Hope this helps anyone to be not as stupid as me

Although the compiler does issue a warning, a character is stored as a number ie. it can also be treated as an integer.
So instead of returning 0, it would return it's ASCII Value which is 48.

48 = number 48
'3' = Referes to the ASCII table, in this case : The number "0"
"48" = Prints it out as a character.

ASCII Here
