1. Please use [code]//code goes here [/code] tags.
2. Please read http://www.cplusplus.com/forum/beginner/1/ . Basically we need detailed information, including a verbatim of the error messages. Don't make us guess what the errors are: Tell us.

Lines 38 to 49 (in this post) are outside a function. They need to be inside a function.

In line 68, you try to use a variable called "userguess" that you did not define.

I suppose that line 76 is meant to be a comment line??? Same for line 78 and 82.

All the errors deal with the line of the for function:
(42): error C2059: syntax error : 'for'
(42): error C2143: syntax error : missing '{' before '<='
(42): error C2059: syntax error : '<='

(42): error C2059: syntax error : '++'
(42): error C2059: syntax error : ')'

Lines 44 to 50 do not belong to the function main() or any other function. They need to belong to a function.

Line 53 is not doing anything. Line 55 produces recursion but there's no condition to avoid a stack overflow. Lines 58 and 59 are not valid C++.

You are also missing the closing brace of the for loop in line 40. You open a brace in line 41 but you don't close it. This is one of the reasons to use proper indentation: To easily see where you are missing stuff like closing braces.

ok, can you help me word them the way they should be? Im completely new at this and still a bit lost
webJose (2948)
Well, I cannot fix playgame() if I don't know its purpose and intended return values. As it is right now, I think you want to use it to determine if the user won or lost. But you clearly have a lot of wrongs in the very basics of C++. I recommend that you study the basics before moving on to functions and the like.

For example, it seems that you want to return 0 or 1, but you always return 0 (see line 61).
xokelz04 (6)
yes i believe i do want to do that. This is all play game is: //this function runs one game. It for checks either 6 incorrect guesses or correct guess.
//It returns a 0 if the game is over and the player did not guess the letter, otherwise it returns 1.
int PlayGame(char answer);
