Program that Prints Some Statistical Results Worksheet

Write a program that reads a text file, then prints some statistical results about its contents to an output file. The results will be primarily an analysis of the characters in the file, which will include the frequency of occurrence of certain categories of characters, as well as the frequency of occurrences of each of the letters of the alphabet.

Note that in most standard English text, certain letters typically appear with a higher frequency than others. This kind of information has been used in setting up games like Scrabble (letter frequencies and point values, etc), as well as more serious applications like decoding encrypted messages and cyphers.

Details and Requirements

Read the contents of the input file, and then print to the OUTPUT file the following information about the contents of the input file:A header stating a general heading and the name of the input fileThe total number of characters contained in the fileA chart (with headings) where each row lists a category, the number of occurrences of that category of character, and the percentage of the total file this makes up. These are the catgegories:LettersWhite spaceDigitsOtherNote that the percentages in this chart should add up to 100%A heading “LETTER STATISTICS”Another chart (again, with headings), listing a category, the number of occurrences of that letter type, and the percentage of all LETTERS this comprises. This time, the categories are Uppercase letters, lowercase letters, and then each fo the individual letters of the alphabet (i.e. 26 of them). So this chart will have 28 rowsNote that the percentage of uppercase + lowercase should add up to 100%Also, the percentages of the 26 alphabet letters should add up to 100%Specifically, note that these are percentages of the total number of letters, NOT the total number of characters in the fileA heading “NUMBER ANALYSIS”, followed by the count, sum, and average (to 2 decimal places) of all integer numbers appearing in the file, where a number is defined as any consecutive sequence of digits bounded by non-digits. Examples: I am 14 years old and it is now 11:15 AM and my IP address is 123.45.0.204In the above passge, there are 7 “numbers” (14, 11, 15, 123, 45, 0, and 204)

General Requirements

• No global variables
• You may use any of these libraries (no others):iostreamiomanipfstreamcctype
• Write your source code so that it is readable and well-documented
• Part of assessing readability and style will be how well you break your program into appropriate functions. Note: Breaking it up into functions makes for smaller, easier-to-code segments. You’ll make your work easier if you do so.

Sample input file – file2.txt:

The quick brown fox jumped over the lazy dog.How lazy was he? Well, he was pretty darn lazy, I’ll tell you.And speaking of the fox, why was he jumping over dogs anyways?He just leaped his 123rd dog. Didn’t he have anything better to do with his time?When he checked his watch at 12:45 PM, 15 more foxes jumped overthe lazy dog, who so far had dreamed of chasing 100 sheep, 17 cats,2 rabbits, and 13 mailmen.Sample program execution(underline denotes user input)Please enter the name of the input file.Filename: file2.txt Please enter the name of the output file.Filename: out2.txtProcessing complete
