Hash Table C++

I need help in solving the collision and inserting the word to hash table

Write a program that uses hashing for the following problem. Given a natural language text, generate a table of distinct words with the number of occurrences of each word in the text. A word is defined as a series of alphabetic characters of length> 5. Note that punctuation and spaces can both (separately or together) delineate a word. Capitalized versions of a word are considered the same as the lowercase version, so feel free to change all words to either upper- or lowercase.
