Console Tree

[pogrady]

I saw a homework assignment about drawing trees in the console window so i thought Id try my hand at making one.

Here you go!

	int RandomTreeType = rand() % 10 + 1;

	switch(RandomTreeType)
	{

	return "No Tree";
};

int main()

	int h = 0;
	char Answer = 'y';

	//get a handle to the console

I'm a newb, so this is probably a dumb question, but......
Using Code::Blocks, I get the following error when I Build it.

C:\Program Files\CodeBlocks\MinGW\downloaded\Tree\main.cpp|96|error: 'time' was not declared in this scope||

Is this a cockpit error on my part, or is this a valid bug?

[pogrady]

It compiles on vc 2010. I need to include time.h.

Thanks.

@ redeemed: The function "time()" is exposed in the header file 'ctime'. This should be included at the top of your application.

Here is a new version of the tree builder. I included a check to see if the input is valid.
