is it possible to assign a number to a character as a constant?

[muzihc]

What I want to do is have printf print a variable which will randomly generate either the number 1 or 2. But I want the number 1 and 2 to be printed as X and O, respectively.

void printRndm(int input)    //input is assigned to randomly generate either 1 or 2
{
   printf("%d", input);
}

So would there be some type of constant declaration I could put in this function that has it print 1 or 2 as X or O?


edit:
title should read: is it possible to assign a character to a number as a constant?

Tricky version:

printf("%c", (input == 1)?'X':'O');

Tricky version 2:

char table[2] = { 'X', 'O' };
printf("%c", table[input-1]);

Simpler to understand version:

if (input == 1)
   printf("X");
else
   pritnf("O");

void printRndm(int input)
{
    switch(input)
   {
        case 1: putchar('X'); break;
        case 2: putchar('O'); break;
   }
}

void printRndm(int input)

   putchar(70+9*input);
}

Depending on this
79 -> O -> 1
88 -> X -> 2

That's obfuscation, in my opinion.

It is only consecrated on this specific problem and nowhere else.
Of course this is no algorithm neither technique and not easy-readable. It's a mess but still a thought.

It's also not portable to non-ASCII systems.

That is not very unicode compliant... then again, my point is moot since putchar() isn't unicode compliant either....

Example:

#include <stdlib.h>
#include <stdio.h>
 
static char printable_characters[256];
 
void printRndm(int input){
  static int init = 0;

  if(!init)  {
    memset(printable_characters, '0', sizeof(printable_characters));
    printable_characters[1] = '1';
    init = 1;
  }

  putchar(printable_characters[(usigned char)input]);
}

Buzz ... FAIL!

If you ever have to look at an ASCII chart to work out what a program outputs then the code is just plain wrong.

I'd probably prefer something like matsp's version 2, since the table can be declared once and used throughout the program, and if you want to change the chars to lowercase for example, you only have to change one place - the table.

const char* table[] = { "X", "O" };

printf(table[input-1]);
