Character Analysis
If you have downloaded the source code you will find a file named text.txt on the Chapter 08 folder. Write a program that reads the file's contents and determines the following:
The number of uppercase letters in the file
The number of lowercase letter in the file
The number of digits in the file
The number of whitespace characters in the file
Write a program that reads the text file's contents and calculates and outputs the following in this order:
• The number of words in the file
• The number of lines in the file
• The number of uppercase letters in the file
• The number of lowercase letters in the file
• The number of digits in the file
• The number of letter H's in the file
• The number of whitespace characters in the file
NOTE: Your program should include at least one try-except error handling statement block. Your program should also validate any input that could cause your program to crash.

- Big State University The Big State University course catalog reads as follows: "To enroll in MIS 260, which is an advanced course, a student must complete two prerequisites: MIS 120 and MIS 222. A student who completes either one of these prerequisites and obtains the instructor's permission, however, will be allowed to take MIS 260." Tasks 1. Create a decision table that describes the Big State University course catalog regarding eligibility for MIS 260. Show all possible rules. 2. Simplify the table you just created.
