Write a C++ program to create Huffman codes. Program input is a file called freq.txt (make up your own file for testing) that contains data on the characters in some cleartext file in the form of each character's non-zero frequency of occurrence in the cleartextfile. (Note that these are frequency counts, not percentages, and it doesn't matter if the values do not sum to 100.) You can assume that freq.txt contains only characters from the standard ASCII 128 character set and that the results are ordered by the ASCII integer for each character. The end-of-line character in a text file is a non-printable line feed character, with ASCII code 10, and will be written in the freq.txtfile as LF. Thus the freq.txt file might look like

LF 2

c 3

d 5

e 14

f 2

Your program should create a "code table" that gives each character and its binary Huffman code. Save this information in an external file called codetable.txt where each line of the file is a character and its code, ordered by the ASCII value of the character.
