Question

The purpose of this assignment is to give you practice using text and data processing techniques in order to compute some statistics about a file of text. The assignment will also give you a chance to learn more about strings and files and about how to organize a moderate-sized program. Construct a program, stats.c, to examine the characters and words in a data file, getty.txt. Your program should perform the following operations: • Count the number of lines in the text. • Count the number of words in the text. • Calculate the average length of all the words in the text. • Display a histogram of the length of words in the text, i.e., a bar graph such as: 1: 2 * * 2: 6 * * * * * * 3: 3 * * * 4: 8 * * * * * * * * to indicate that there are 2 one letter words in the text, 6 two letter words, 3 three letter words, 8 four letter words, etc. • Count the number of characters in the text, excluding blanks and punctuations. • Display a table showing the frequency of each letter in the text • Count the number of vowels in the text and output the frequency of each vowel as a percentage of the total number of vowels read. Remember that the main() function should appear as the first function in the program. Be sure to use function prototypes for each of the functions that are used in your program. Pass all file names to this lab as command-line-arguments. The contents of getty.txt is given below: Four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal. Now we are engaged in a great civil war, testing whether that nation, or any nation so conceived and so dedicated, can long endure. We are met on a great battle-field of that war. We have come to dedicate a portion of that field, as a final resting place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this. But, in a larger sense, we can not dedicate -- we can not consecrate -- we can not hallow -- this ground. The brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or detract. The world will little note, nor long remember what we say here, but it can never forget what they did here. It is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us -- that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion -- that we here highly resolve that these dead shall not have died in vain -- that this nation, under God, shall have a new birth of freedom -- and that government of the people, by the people, for the people, shall not perish from the earth.
