Project 9

The Projects

Project #9.1: Write a program that reads from a file of real numbers, and displays the minimum, maximum, average, and range of the numbers in the file. The user should be able to enter the name of the input file from the keyboard.

Project #9.2: Write a program that reads the contents of a file and creates an exact copy of the file, except that each line is numbered. For example, suppose the input file contains the following text:

'Twas brillig, and the slithy toves
   Did gyre and gimble in the wabe;
All mimsy were the borogoves,
   And the mome raths outgrabe.
                        - Lewis Carroll

Then the output file should appear something like this:

1: 'Twas brillig, and the slithy toves
2:    Did gyre and gimble in the wabe;
3: All mimsy were the borogoves,
4:    And the mome raths outgrabe.
5:                         - Lewis Carroll

The user should be able to enter the names of the input and output files from the keyboard.

Project #9.3: Using the PigLatin() function we wrote in Lab #6, write a program that reads a file of words and translates each word in that file into Pig Latin. The user should be able to enter the names of the input and output files from the keyboard.

Project #9.4: Write a text-analysis program that reads an essay or composition stored in a text file, and determines the number of words, the number of sentences, the average number of words per sentence, the average number of letters per word, and a complexity rating, using:

complexity = 0.5 * averageSentenceLength + 0.5 * averageWordLength

Based on these calculations, your program should assess the writing level of the essay as:

• Grammar School if complexity < 6.
• Junior High if 6 <= complexity < 7.
• High School if 7 <= Complexity < 8.
• College if 8 <= complexity < 9.
• Graduate if complexity >= 9.

The user should be able to enter the name of the input file from the keyboard.
