char arrays

-----------------------------------

I don't know, I feel like I'm not learning anything.  I figured that I'd use streams to and convert to them to chars with the transform function, but then I realized I needed a unary function that would deal with the chars.  

So then I started to write a test version of just such a function when I ran into some complications that I don't understand and I feel stupid and retarded for not understanding.

Here's the code.  


#include 

using namespace std;

char toBinary(char hexNum)
{
   char charArray

One immediate problem jumps out at me.  When you call toBinary, you're providing a const char*, but your function takes a char.

Yeah I don't get how it figures its a constant char.  If i declare it a char, and then pass it a char, even though its a constant char shouldn't it be treated as a char?  

But thanks though, I didn't realize that was what the compiler was talking about when it said error converting from const char to char.

Chars are delineated with single quotes.  String literals are surrounded by double quotes.

Oh!  and i realized my other problem was not doubling up on the equal signs.  *smacks himself*

But I'm not even going to bother doing it this way, I'll just stick to strings since it will be much easier.
