Missing Logic Looping Through Switch Statement

Having trouble with the logic when looping over this switch case again:

Code:

for (j = 0; data[j] != 0; j++){
     switch(data[j]){

    case 'c': 
            output[j] = ranit(r_brace_array);
            break;
    case 'h': 
            output[j] = ranit(pipe_array);
            break;            
    case 'e':
            output[j] = ranit(tilday_array);
            break;
    case 's':
            output[j] = ranit(comma_array);
            break;
    default:    
            break;        
         }
     }


     for (i = 0; output[i] != 0; i++) {
         printf("%x\n", output[i]);
     }

It calls a function (ranit) that assigns a letter a random hex number from an array and it works fine. However, if I give this program the phrase 'cheese' you will noticed that '85f31aae' is displayed for every instance of the letter 'e':

Code:

$ ./test
Gimme something: cheese

a4d19a86
1ad33008
85f31aae
85f31aae
3927bca6
85f31aae

What I want is the function ranit() to be called again if a letter repeats. This way a repeating character does not get a repeating number. I tried making an additional outer loop, but the results did not change.

Again, had to post a code snippet due to length of code.

If anyone can help with me with the logic its greatly appreciated.

break(1T)						       Tcl Built-In Commands							 break(1T)

__________________________________________________________________________________________________________________________________________________

NAME

       break - Abort looping command

SYNOPSIS

       break
_________________________________________________________________

DESCRIPTION

       This command is typically invoked inside the body of a looping command such as for or foreach or while.	It returns a TCL_BREAK code, which
       causes a break exception to occur.  The exception causes the current script to be aborted out to the  innermost	containing  loop  command,
       which  then aborts its execution and returns normally.  Break exceptions are also handled in a few other situations, such as the catch com-
       mand, Tk event bindings, and the outermost scripts of procedure bodies.

EXAMPLE

       Print a line for each of the integers from 0 to 5:
	      for {set x 0} {$x<10} {incr x} {
		 if {$x > 5} {
		    break
		 }
		 puts "x is $x"
	      }
