Can i use switch-case with characters?
PostPosted: Sat Mar 26, 2016 12:58 pm     Reply with quote

Hi, can someone help me please?

can i use switch function with characters?

I'm building a propeller clock, for this i want to add into my code (once i have it ) a function that receives an argument (A-Z or 0-9) and send the data through PORTB.

Example:
Code:

SYMB(C); //Where SYMB is my function or subroutine
SYMB(C);
SYMB(S);

------------------

char SYMB(){
switch SYMB
  case C:
  PORTB=XXX;
  break;

  case s:
  PORTB=XXX;
  break;
}

Or something like this Smile

Any ideas?

Almost.

Code:
void SYMB(char c) {
   switch (c):
      case 'C':
         ...do something
         break;
      case 's':
         ...do something else
         break;
}

Code:

void symb(char val)
{ //you were saying that the function returned a character
//not that it accepted a character
   switch (val)
   {
   case 'C': //This is the character 'C'
       output_b(xxxx);
       break;
   case 's': //The character 's'
       output_b(yyyy);
       break;
   }
}


Generally in C, use the standard that ALL CAPITALS is a #define.

For the rest, get a C textbook....

I see Newguy posted while I was typing.... Smile
