- Students will learn how to use Perl as a tool to solve problems at work and to enhance their resumes. This course uses a multi-sensory approach to teaching Perl. In other words, you will Hear about Perl in lectures, See Perl in action through live demos, touch Perl by downloading and experimenting with any of the dozens of available program examples, and work with Perl Mentally by going through the exercises.
- You should be comfortable using a computer. Your computer skills should include the following: (1) the ability to get on the Internet and go to websites; (2) the ability to access and use your computer's command line; (3) knowledge of how to navigate folders or directories on your computer; (4) the ability to create and edit text files on a Windows computer, or regular files on a Unix-based computer. Also, some programming knowledge will be very helpful.
This course will teach you Perl through a multi-sensory approach.
- You will hear about Perl in lectures.
- You will see Perl work through live examples.
- You will touch Perl physically by working with the dozens of downloadable working Perl programs you will have access to and that are used in the live examples. You can use these programs to experiment with and as templates for your own Perl programming.
- You will touch Perl mentally by working on the exercises and writing your own Perl programs.
Some of the basic and intermediate level Perl skills you will learn in this course include:
* Downloading and installing Perl on your computer
* Using Perl to work with numbers and strings. This could be used to do mathematical calculations and to manipulate strings.
* Read data into your programs (for example, .csv files, data from the keyboard, regular files, etc.), detect data patterns, and alter that data with regular expressions and various Perl functions
* Store lists of data in arrays and hashes
* Use subroutines to create larger programs and to break your programs up into manageable pieces
* Access and use ready-made code (modules)
* Create, modify, read, write, and append files. Combine files, concatenate files.
* Use File Tests to get information that you can use to make decisions about files, much like you'd do as a systems administrator.
* Use References to Create complex data structures (e.g. arrays of arrays, hashes of hashes, hashes of arrays, and arrays of hashes).
* See all of the above in action and practice what you learn by writing your own programs
- IT professionals that want to increase their value in the marketplace by adding Perl knowledge to their skill set.
In this lecture, you will write and run your first Perl program -- the helloworld.pl program. We'll examine each statement in the program so that what it does is clearly understandable. You'll also see the helloworld program run on both a Unix and a Windows computer.
After completing this lecture, you will know what String Literals are, you'll know what String Scalars are, you will have gotten exposure to Perl's string operators, you'll understand the differences in how Perl interprets strings between single quotes versus those between double quotes, you'll have gotten a view of Perl's "backslash escape" sequences and you'll know how to make use of them. In addition, you'll do an exercise using strings.
After going through this lecture, you'll know how to get user input into your Perl programs by using the "line input operator". Also, you'll know what the "chomp" function is, what it's for, and how to use it. You will also begin to see how what you've learned so far can be used to create a program (the "calculator" program), and how pseudo code can be useful in creating your Perl programs.
You'll learn about Perl's "Binary Assignment Operators", how to assign values to variables, how to use Perl's operators on variables, and how to use Perl to solve a classic Computer Science problem -- the "Exchange the values in Two Variables" problem.
After completing this lecture, you'll know about "if" control structures and Perl's string and numerical comparison operators. You'll also know how Perl decides if a condition is "true" or "false". You will use this knowledge as you continue to build the "calculator" program.
You'll learn to create and use while loops in Perl, you will learn about Perl operator precedence and associativity, you will see how to set your own operator precedence and associativity by using parentheses, and you will see how to complete the "calculator" program.
