Programming Languages Project

You are to write a this program in a language that you are not familiar with. Notably, you cannot write it in Java or Python. The program should have the following specifications:

1. I must input the text file that I have provided on the W-drive named decl_of_indep.txt. You may place this file in the same folder as your program. You must not change this file in any way, other than changes between the end-of-line characters that might occur between Unix, Dos, and MacOS (which will not make any difference to the results).
   
   
2. Your program must keep track of the number of times that a word appears in the text. This is case insensitive so The, the and THE are the same word. A word is defined as the longest unbroken string of alphanumeric characters. Thus, It's July-the-4th, 1776! has 6 words: it, s, july, the, 4th, and 1776.
   
   
3. Your program must print the top 20 most frequently used words in descending order (most to least frequently occurring). If the 20th word has the same count as next one(s) then continue printing the 21st, 22nd, and so on, until you reach a less frequently occuring word.
   
   
4. The output should show three columns and they should line up like columns normally do. The first column should be a line number (1, 2, 3, ...). The second column should be the word (printed in lower case). The third column should be the frequency count for that word.
   
   

Example languages you can use are Perl, PHP, JavaScript, Bash script, Forth, APL, Pascal, or any other unknown language to you. You may need to find a free compiler or interpreter to install in order to do this. Be prepared to tell me what I must download to run (and recompile) your code. You must turn in your source code and a copy of the output (make sure your name is included in the comments and output.
