C++ Arrays

Hi everybody, I would like some help doing this, I got the first part down, having a bit of a problem with the second.

I'm making a "hangman" type game using arrays and for loops...when the players enters a letter in the array, the letter should go into its spot in the word and be replaced with a zero (0) in the array...if its not there, then it should count that as a miss and start the cycle again. Here's what I have so far, which is simply array initializing the alphabet.

void initAlpha(char alpha[])
{
int i;
for(i=0; i<26; i++)
alpha = 'A' + i;
}

and I can't even get started as to what to do about this guessing letter and putting zero in its place thing. PLEASE HELP!!!! It will be much appreciated --- thanks

Hang in there .. man! paching!

After I saw this question, I got to thinking about how to go about making a hangman program. And, except for the getRandomWordFromFile beast of a function, I wrote the rest. My coworker helped me tremendously with that one bit.

It works by DOS-prompt only, of course. And you have to make sure you have a wordlist (separated by carriage-return+line-feed) located in C:\TEMP\ called SHORTLIST.txt.

No doubt it could've been written better, but I just wanted to crank this one out. And for my next act, I'd like to try something like that gameshow Lingo. We'll see how it goes.

Best of luck, <b>BiteMe</b>!
