codeblocks has no standard library, codeblocks is not a compiler nor a standard library. Codeblocks is only a IDE that can use a lot compilers. And this compilers can use a lot libraries...

create my own library
what is a library in your understanding? A shared library? A static library? Only a header file? What programming language are you using? In what programming languages this library should be accessible?
What operating system are you using? What compiler are you using?

I am using c language
I read that we can add functions to the standard library so that we don't need to define them in every program
like we can add function to calculate factorial of a number to the math.h file
can't that be done in code::blocks

If you have yet to learn the answer to these questions; then, you do not know enough to do it.

What operating system (OS) are you using?
What compiler are you using?

And, if your book or teacher told you to try to add functions to the "standard" library then you should assume the book or the teacher is wrong a lot of the time.

You could create a "user" library and add functions to it safely. But, till you learn what a compiler and OS is no one can help you on creating a library.

I am using Windows 7 and code blocks for writing my programs
and yes that book said to create the user library and then to add functions to it but it also said to add the function for calculating factorial in the math.h header file

So, you still need to figure out your compiler name and and version.

Do you know how to create a multiple c file program?

Because, you could be confusing that with creating using a "user" library.

A beginner will normally learn to create multiple c file program; before trying to create a "user" library.

And, the first "user" library is normally a static "user" library or a header only library.

Post a build log; so, I can guess what compiler you are using.

well, not still
till now I have learnt till strings and structure data types
I have one more question, how do I use the functions for creating boxes on the screen
well I read a program for it which contained a file named goto.c and has functions like gotorc( r,c) and so on
but when I compile it, it says goto.c file doesn't exist
I am using c language and GNU GCC compiler and I am making the program on console application
should I change the compiler I am using or should I change the project like using some other project like there are AVM project etc. any of them
please explain

post a full build log. From the build log tab as described here:
http://wiki.codeblocks.org/index.php?title=FAQ-Compiling_(general)#Q:_How_do_I_report_a_compilation_problem_on_the_forums.3F
You have to add the goto.c file to your project so codeblocks can find it. Project->Add file

well I read a program for it which contained a file named goto.c and has functions like gotorc( r,c) and so on
i don't think that drawing boxes is easily possible on modern windows machines.

You are good to go with the gcc  it is quite standard compatible and ok fast. What is AVM? If you change the compiler as soon as you hit problems you will gonna run out of compilers quite fast. The compiler is never (or at least at your level) a problem, but always the user. And a other compiler won't fix this.
The problem with beginner like you is we don't know how to help you unless you learn the right wording. You talk about libraries but mean only additional c files. You talk about the standard library and you even don't know what the std library is... If we read your post we think over complicated and begin with complex concepts and this will intimidate you even more...
So to create a library like i think you mean (aka using multiple c files) you simply add the second c file to the project. Or even more simply you go to File->New->File..-> select source or header file->Go->Next->select "C"->Next->Press "..." and select the save folder for the file. It is convenient if the file is in the same folder as the project, select "All" targets->Finish
Now you can enter the code in this file. You will need a c and a h file to be able to move your function to the new source file. You define the function in the c file and declare the function in the header file. Then you have to include this header file in your main c file. But this is out of scope of this forum. We help you by doing this steps with codeblocks. If you have a compiling problem please post the build log as described in the top link.
