Battleship

[gonzo86]

Hey, Im kind of new to C++ and I'm working on making a Battleship
program. I need to be able to output a screen with just dots on it for
when people havent tried those spots and then be able to switch it with
the characters in my array after they have been picked. This is the
code I have so far. Right now all all I want to do is make a game where
you have to sink the computers ships in less than 50 turns. Thanks for
any help that I get.

We'd be happy to help you, but what is your question?

Im just not sure exactly how to print a 2d array so that it would look
like the board and be able to change the different dots on it every
time someone guessed the position.

Please quote the message you are answering to.

I guess you are looking for a way to specify a coordinate to output a
character; this is impossible in standard C++ (the subject of this
newsgroup). See

http://www.parashift.com/c++-faq-lit...html#faq-15.19
http://www.parashift.com/c++-faq-lit...t.html#faq-5.9

for more informations. You'll probably be disappointed by the graphical
possibilities of standard C++, but that's the way it is. One standard
way would be to output the grid one cell after the other, checking
what's in it and displaying the correct symbol. To "clear the screen",
just ouput a few empty lines and output the whole grid again.

Are there any ways of just using standard C++ to do this that would be
easier?

Not in a standard way, assuming you want to redraw the screen. There
just isn't a standard way of doing this.

So you can either redraw the grid, scrolling down the screen each time,
or use a terminal manipulation library specific to your platform.

By the way, to quote correctly on google, see

Hard coded numbers aside....:

for( unsigned y = 0;
{
for( unsigned x = 0; x < 9; ++x )
{
cout << map[ x ][ y ];
}
cout << "\n";
}
