I am writing a program that deals with ciphers and codes. When the user enters a set of text and a number after being prompted, they are taken to this function:

(Toggle Plain Text)

for (i = 0; i < len; i++)
    { 
         workingtext[i] = workingtext[i] + ikey; //add the key to the plaintext                                                                                            	
    }                                                                                           	
    return workingtext;
}

where len is the length of workingtext

I want the resulting workingtext to only be a letter a-z, not any of the wierd computer characters (e.g. smiley faces, musical notes and french circumflex accents (just some of my favourites)). I think that it probably just requires a modulo thingy in here somewhere, can some one indicate where?
