DATES:

1. Perl Datatypes
   • Write a program that 1- Reads a series of chars - one in each line. 2- Prints a list of the decimal ASCII value.
   • Write a program that 1- Reads a series of numbers - one in each line. 2. Prints a list of their char ASCII value.
2. Built-in Functions
   • Turn on strict and warnings.
   • Write a program which 1- Accepts a list of numbers - separate lines 2- Prints for each number: "The number is odd (X)" - for odd numbers. "The number is even (X)" - for even numbers.
3. Conditions and Loops
   • Write a program that reads in a list of strings on separate lines and then prints out the list of strings in reverse order - without using reverse on the list.
4. Regular Expressions
   • Write a Regular expression to delete duplicate words.
   • Write a regular expression to match a valid e-mail address.
   • Write a regular expression to match a valid IP Address; reminder the 0.0.0.0 is valid, but 300.0.0.0 is not.
   • Write a regular expression that takes a line and prints only the words that have an odd number of letters.
5. Subroutines
   • Write 2 functions: The first returns the sum of its arguments: the second returns the multiplication of its arguments.
   • Write a function that takes 7 values; the function throws an exception if any other number of arguments has been entered.
   • Write a function that takes three numbers and returns the sum of the tens digit of them all. For example, the inputs: 120, 140, 220 should return 8.
6. Data Structures - Advanced
   • Populate a large sparsely populated n-dimensional matrix.
7. Multidimensional Arrays
   • Populate and traverse a three-dimensional array.
8. Complex Data Models
   • Create a n-dimensional matrix in Perl with arrays of arrays of arrays.
9. Module Creation for Code Reuse
   • Code a generic numeric checking function.
10. Developing Modules from Subroutines
    • Make a module that calculates the product of two matrices and prints it on STDOUT.
11. Building Object Oriented Systems
    • Write a simple class to print out the day of the week using the Zellers congruence formula to get the day of the week given a date.
    • The instructor will provide the formula in Perl code.
12. Object Oriented Concepts
    • Create a class to list the entire directory tree when given a path name.
13. Writing Object Oriented Modules
    • Write a Perl class that manages shipments to customers.
    • Code a separate initialization method for a class to be part of the new constructor.
14. External Modules
    • Get Perl modules with C code.
15. Modules Bundled with Perl
    • The use of the diagnostics pragma generates additional diagnostic messages when compiling and running programs.
16. Locating and Installing External Modules from Internet Archives
    • Install the external module supplied by the instructor.
17. Programming Techniques
    • The map built-in function is a very useful tool.
    • The map can be used to give a list and apply a code block to every element returning the list.
    • Create a hash slice to avoid looping.
18. Multiprocessing Programs in Perl
    • Spawn a thread by using the Thread->new class method.
19. Portable Code
    • Code a Perl program that runs in Windows, UNIX, and Linux.
20. Code Optimization
    • Profiling a supplied program can be used to identify the functions which are consuming the most resources.
