Hey i was wondering if someone could have a look at this and help me figure out why the output is repeating it's self and how I would fix it. I have spent several hours trying to fix this. Thanks in advance.

The program atm currently generates a word from the choice

"plasma", "chicken", "mouse"

Just a quick glance at 160 shows you're rebuilding the string named "Length" every time. Is that correct?

...and at 95, you're displaying and adding simultaneously. Is that correct?

Yes the line at 160 i belive is my problem I don't wish to rebuild the string "Length" EVERYTIME so that it duplicates it self.

Line 95 has now been taken out

the code at 95 was oringally to replace the random word as " _ " for the number of char's in the word for example "_ _ _ _".

I then changed it to "-" then setup a char array so that I could store the input from the guess entered, That didn't work so then I tried to set up my if statments saying if the word is displayed with a "-" replace with the guess which was entered and if the word has a letter do not replace.....

Sorry if this seems confusing, this code has been doing my head in =[!

Problem is now closed
