Question

You are employed by the NSA (National Security Agency) and you have received the following message that contains the following text:

“George Smiley arrived in Prague on Friday evening at 10:50 PM. ……”

See TTS.txt

A quick analysis of text can be achieved by storing each word in a hash table. After storing all words in a hash table you will then be able to print all the words stored in each row of the hash table.

Requirements:

Create a hash key value (int Key) and init to a prime value (13)
Create an array of string pointers S_ptr[13]
Each string pointer, S_ptr[i], should allocate on the heap an array of strings (size 35)
Initialize all row elements of hash table with ‘#’
Read the text, one word a time, and compute its hash index value (int Hash(string Word)
The Hash function should take the numerical sum of all the characters in the Word and calculate (Sum%Key )which is then output to the program as an Index. Recognize that output Index can have only values ranging from(0-12)
Store the word in the hash table row number obtained from the previous step (Index)
Add the input Word into the next free element is the hash table row. The next free element is decided by finding the next ‘#’ value
After storing all Words in the hash table, print the contents of all rows
Print the total number of words in each row
Sort (bubble sort) the words in each row and print again your results
Provide some conclusions to this analysis
