hey, i have made a game called zombie island. this is what needs to be included in the game:

This is a simple turn based game.
Set up a 2d grid. Onto the grid randomly position holes, zombies and a man (each represented by a simple character e.g. O Z and M).
The man moves according to input from the player (suggest 4=left, 6=right, 8=up and 2=down).
The zombies should move in a random direction.
If the zombies land in a hole then they die and are removed from the game. If all the zombies die the man wins.
If the man lands in a hole or a zombie lands on the man then the man loses.

here is the code i have created:

errors are produced when this is compiled and ran. i am using visual c++ 2005 as my compiler, i would be very grateful for any help given. thank you.

ps. i submitted another thread about the same game, but that was for help with a more advanced version. this is for the basic version of it. sorry for any confusion for people looking at it.

You might wonder why your problem hasn't been answered. It is obvious that you haven't use the code tag which make it very unfriendly to read your code. I recommend you to tag your code and post your error messages.

Here is the key of having a successful question: (if you follow this guide correctly, I am sure that many people will answer your question)

Describe your problem clearly and fully!

So you have a great title and you're ready to compose a post. Resist the temptation to copy and paste your code and as an afterthought say "It doesn't work". That's not a description of the problem. If you want help, you have to give us enough information to work with. Include at least all of the following in your description of the problem:

1) An overview of what your program does.
2) The result of your current code.
3) What you expected your code to do.
4) The contents of any input files (if appropriate)

This tells us what context your program is in so that we can offer alternative solutions. It tells us exactly what your code does so that we can more easily pinpoint the problem without performing tedious troubleshooting steps. Finally, it tells us what you wanted your code to do so that we can compare what it does with what you wanted it to do. Most of the time, a knowledgeable member can answer your question almost immediately using just this information.

Keep the code short and sweet!

As much as we don't care, people insist on posting pages and pages of irrelevant code. Keep the code as short as possible. If the code isn't short, make it short by cutting out as much irrelevant code as possible. Ideally, we expect you to write a small test program that exhibits the problem you're having.

The benefit of this is twofold. First, you might end up solving the problem yourself. Second, if you can't solve the problem yourself, there's less code that we have to look at and the problem is more likely to jump out at us.

Use code tags!

There are two ways to wrap code in code tags. The easiest way to do this is to select all of your code and then click the # button on the message editor. This will automatically wrap the selected text in code tags. Without code tags, all leading whitespace will be removed from the code, so nicely formatted code ends up having no indentation. This makes the code very hard to read and many members will refuse to help you because they can't read your code.

commented: Absolutely! No code tags == ignored code +19

the problem i'm getting is :

i have played around and tried lots of different things, but cannot seem to get it to run.

First of all, `getch()` need header `<conio.h>` if my memory serve my right. However, `getch()` , somehow, was not recommended to use.

ok, i inlcuded <conio.h>

when i run it now, i get this error:

error C4716: 'play' : must return a value

what do i do to solve this?

the error lies in this part of the code

``````bool play(int nrz,int nrholes,int plain[10][10])
{
endgame = false;
while (true)

{
endgame = movezombies(plain);
nrz = nrzombies(plain);
if (nrz==0){ cout << "human win" ;break;}
}
}``````

Play is a boolean function, so it needs to return true or false. If you don't want it to return anything, change it to a void function.

thanks, changing it to void makes it run now, apart from i get a few warnings.

the warnings i dont understand is:

warning C4700: uninitialized local variable 'dead' used

here is the part of the code that the error occurs in.
