I know Pascal is one of the oldest languages out there, but I'm learning it in school, and I wanted to make a Rubik's Cube solver. I'm having problems with storing the user input to an array. Here's the part of the code that's giving the error:

Code:
c:=readkey; {c is the color input by the user on the messed up cube}
cube[cnt2]:=c; {cube is the array, and cnt2 is the variable for which slot in the array to put c in}

I know it's not very descriptive, but can anyone help me? I'd be glad to give more information on the code itself, if it would help. Thanks!

Edit: oh yeah, and the error is "Error 26: Type Mismatch"

My guess is that readkey returns a character but your array contains numbers.

ahh, thanks. I tried it and it works now.

The only other problem I'm having for the time being is another array problem. Is there a way to sort an array of real numbers in ascending order? I can't find any built in command, so do I have to sort it manually?

A basic bubble sort would take five lines of code and two minutes to write. Unless it's a really frickin huge array, you don't really have to worry about any more advanced algorithms, although they are good programming practice in any case.

When you say "frickin huge array", how big would that be? Cause the array I'm sorting is about 50 numbers.

50 numbers is definitely small enough not to worry about which algorithm to use. I think you'd be noticing a difference between algorithms at 1000 or so elements?

OK, then. I'll try it out, and let you know how it goes.

the algorithms I have seen for rubric cube solvers that are somewhat decant are extremely complicated and slow, so how do you plan on making yours?
Also why not just use C, it is a much easier programing language and you would probably not be having these problems.

I am using a pretty complicated method. I think the algorithms used are somewhat similar to the ones used in the one for the calculator (can't remember who made it).

I don't know C or C++ yet, so I'm starting with pascal. Mostly cause it's so similar to TI-BASIC.
