Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have an assignment "Write a Bash script that removes all zero length ordinary files in the current directory. Do appropriate error checking.", and I know for that I have to use an if statement with -s "$1" condition. The only thing I am confused about is that do I have to go through all the files in that directory? and lets say the script file that I created is in Script directory and it has three files. This script will go through all the three files and check its size? If the answer is yes then how am I supposed to pass the three files as an argument to the script. Any suggestions?
You don't need complicated loops. It should be enough to use one liner with find command using some sophisticated switches. A few examples of such commands you'll find here. Analyse them and review man find.
Yeah I think I need to use do-while or while. What I am thinking is that I need to pass the files as an argument one at a time and the script will check the size. If the size is zero it will remove the file and will loop back and check another and so on. How can I pass them(files) to the script I don't understand that.
Or both find and a loop with the loop iterating once for each file given by find. As for the somewhat artificial requirement to use a -s $1 test, that could be satisfied by calling a function from the loop; it would be the function's $1, not the script's initial $1.
