I've been learning C++ for about 9 months and I want to start making a good console game. I'm thinking something along the lines of snake but I'm not so sure where to begin. I think I should have a board (2-d array?) with "@" as the walls. I should have a function for updating the board. I'll have "*" as the snake and "+" for the bits of food. Now for my problem. How do I handle user input given that it uses the arrow keys? I'm looking for all sorts of help here, I'll put up some code when I have it!!!

Having some trouble (already, Not Good!)
What I want to do is create a board, char board[20][20]; and fill it entirely.
If it's a border, I want it to be an '@' and everything else, a space.

I don't really want to hard-code it because it won't teach me anything and there should be a much easier way to do it. Is for loops for every single row the only way?

Also, How do I display a full array? Do I have to go through all that with the for loops for every row again?
Thanks!

Also, for readibility, should I use const chars for borders and spaces?

It's very easy to implement: use a paper and a pen to figure it out, you won't learn, if you don't try to solve the very first complicated problem you encounter by yourself.

All these indexing/grid/hex-grid stuff are always very hard (work) to implement. You have to go through it for yourself, or you will never be able to do it.

I started to program a hexagonal-grid minesweeper 2 days ago, displaying the grid alone took me 2 hours to figure out. Panning an zooming the grid an other 2 hours (and maybe 5 sheets of A4 paper). Not to mention looping through the "neighbor" fields: about 3 hours. Despite that I had done a lot of grid stuff before this. And even a regular square grid minesweeper.

I'm not! I just got to populating the borders and I thought there has to be a better way to do this! I was using for loops as in:


for (int i=0; i<19; i++)
{
board[0]='@'; //populate x axis (border)
}

for (int i=0; i<19; i++) //populate y axis (border)
{
board[0]='@' <<"\n"; //should I be using endl or is there any difference?
}




It's not that I can't do it already, it's just that there should be a way to do it thats faster...

Better tends to be a meaningless term in programming. Define better. If I gave you an alternative solution, what metrics would you use to determine its quality relative to your current approach?

Faster in what way? (Define faster) And why do you believe what you have is noticeably slow?

Don't get stuck in these things. If it works, it works, that's the most important. It's meaningless to start optimizing a code that simple (and that is called once in the whole game, since it's just initialization). Who cares if it's not elegant? It will be better next time. That problem has nothing to do with syntax, or the structure of the language or something, it's worthless (= you won't benefit from it) to spend much time with it.

Ok, Have the board displaying correctly, just needed to think things through first.
I just realised how big this code is going to get, should I learn how to use header files and the like?
I have an idea for the snake's movement, to have a function getting the direction (how?) and then another function to see what will happen if the snake moves there, if it's legal, move the snake and if it's illegal stop the game and show the finished screen with the dead snake's last position. If you understand what I mean, is that how I should do it or is there a better way?
Thanks

You've been learning C++ for 9 months. You have to confront how C++ handles organization of code at some point.

Maybe there is a better way, maybe there isn't. But the point is that you learn. If we feed you information, you don't learn.
