Oh My Gosh, I Need Help With This!!!

Ok, in TrueBasic, i made a tictactoe program. It was awsome and worked perfect. Now, im trying to convert the program to c++.
PLEASE, take a sec and look at the following attachments. The first is the working program in TrueBasic, the second is my attempt at converting it. I get mega errors in the c++ one. I dont know what im doing wrong, and im confused on how to make subroutines and pass variables so i can use the same variables in different subroutines. I dont have to use variable passing in the truebasic version, but i must in c++. Please help me! These are both word documents. Ok nevermind, here is the c++ attempt and there is no attachment. Just say if you want to see it in truebasic (this is really cool). *Keep in mind, I probably dont have the 'void' and 'variable passing' syntax correct, so help me on that please*:

It's hard to know where to start - there are a number of problems just looking at it, never mind compiling it.

All over the place, you have
> board[y][z]!=="-"
When you should have
&nbsp; board[y][z]!=='-'
Not only that, !== is not an operator, you mean !=

> void check_input(int y, int z)
You make no check for z.
In addition, the scope and parameter rules are such that changing y in this function will have NO effect on the caller's copy of y (or z)

> if (board[1][g]=="X" && board[2][g]=="X" && board[3][g]=="X")
Use of "" instead of '' as already mentioned.
And an array overstep problem because you've declared the board as 3x3, but have forgotten that C arrays start at index 0, not 1

> d="X";
Yet more "" when you should be ''

> if choose=="H" || choose=="h"
I think you know about the "" now
But where are the ( ) ?

> showboard(board[3][3]);
Nope this is not how you pass an array to a function. In this case, you need
&nbsp; showboard(board);

If ever there was a good example of how not to do something, this is it.

This has so obviously been written in one go without ever trying to compile it. Of course now, all the mistakes which you should have spotted have been propagated all over the place, and you now have " I get mega errors in the c++ one. "

Personally, I would do these things
1. delete this file (or hide it until later)
2. get a pencil / paper and sketch out the functions you require, plan the interfaces between them and choose how to represent the main data structure (the board).
3. WRITE and TEST each function in turn - do not make a mad stampede for the finish line like you have done this time, otherwise we'll be having this conversation again.

> and im confused on how to make subroutines and pass variables so i can use the same variables in different subroutines.
Then practice on a simpler problem first.
