Books to teach me C, Objective C, Cocoa help please

Question

I want to teach myself Cocoa since I was told thats the best language to start with for a beginner OS X programmer. To do this I need to learn Objective C. To do that I need to learn C. Can someone tell me the best book for learning C, then Objective C, then Cocoa? I have a C book but ive hit a road block and I dont understand it so I dont think something I can use.. The C book is The C Programming Language Second Edition by Brian Kernighan and Dennis Ritche. My Cocoa book that I have is Cocoa Programming for Mac OS X by Aaron Hillegass.. the problem with my roadblock is this file copying program.. it doesnt do anything then the book gives me challenges.. well If my program does nothing then I dont know how to do the challanges which is determine the value of EOF (end of file) as 0 or 1, then print it:
#include <stdio.h>
int main (int argc, const char * argv[]) {
int c;
c = getchar();
while (c != EOF) {
putchar(c);
c = getchar();
return 0;
}

In C, input and output are considered to be files, so you could sort of consider it to be a file copying program in that sense. If you ran it in the Terminal, you could use it to copy files by using input and output redirection.
$ yourProgram <input >output
But that's neither here nor there. The thing is, the K&R book on C isn't really the best introduction for a beginner. It's a great book for a more experienced programmer who wants to learn C, but for a beginner, you'll need something more basic.
I thought the Xcode libraries had its own guides and stuff to learning C Obj C and whatever..
The Xcode documentation does include information for learning Objective-C if you are already proficient with C. It does not include anything on learning C. The information on Objective-C is meant for experienced programmers, not someone who is new to programming.
My advice would actually be to start with a language other than C if you want to learn how to program. Scheme is an excellent language to learn on, but it can be a little tough if you're not taking a class on it; if you're feeling ambitious, you can try reading The Structure and Interpretation of Computer Programs, which can be found here: http://mitpress.mit.edu/sicp/full-text/book/book.html. This is how I learned to program, and it gave me the background to easily learn the other languages you need.
If you're not feeling quite as ambitious, or if you want to get started doing Cocoa programming as soon as possible, Ruby and Python are both pretty decent languages. They're much easier than learning C and Objective-C, and they have pretty much full access to all of the Cocoa programming interfaces on Leopard. I prefer Ruby myself, but some like Python better.
