I can do parts a. and b. just need help writing the code!

Problem- 1: Assuming you have to submit a term paper as a text file with a specified word limit. Develop a C++ program that counts the number of words in a standard text file. You may use any generic text file or use a sample text file attached along with this Homework. Also determine the number of occurrences of each letter from "a-z" in the text file. Note, that the counter need not be case-sensitive and this program should have an array variable to update the 12 Points 8 Points counter for each alphabet. e.g. occur[26 a. Draw a detailed flow chart in a document file, indicating the necessary array declarations, and the algorithm used in this program, to (1) count the words, (2) the occurrences of letters from "a-z" and (3) vowels (ie. a,eji.o.u). input and output screens (i.e. showing the total word count), and in the sample text file you have used. b. In the same document file, prepare a help section that documents the sample text file, the sample 1. Prepare a bar graph that shows the number of occurrences of each of the vowels (i.e. a,e,i,o,u)
