can use pseudocode) Refine the algorithm successively to get step by step detailed algorithm that is very close to a computer language. Pseudocode is an artificial and informal language that helps programmers develop algorithms. Pseudocode is very similar to everyday English. Pseudocode & Algorithm Example 1: Write an algorithm to determine a student’s final grade and indicate whether it is passing or failing. The final grade is calculated as the average of four marks.

Unit 8 Homework Short Answer: 6. a loop that never hits a max value or that never turns true is infinite While (number >=0) Console.ReadLine(“Enter a positive number”) number = Console.ReadLine() End While 7. A count-controlled loop 8. You need to initialize so you don’t fall into an infinite loop. 9. You can let user control the number of times it executes 10. Algorithm Workbench: #3: For counter = 0 Step 1000 Console.WriteLine(“Value ” & counter) counter = counter + 10 #4: Dim sum as integer

Explain The Regress Argument’ for Foundationalism. Why does Dancy hold that this argument is fallacious? Is he right? One of the primary questions concerning epistemology is that of how we justify true beliefs? The regress argument is a problem imbedded in epistemology and‚ in general‚ a problem in any given situation where a statement or belief has to be justified. The Regress argument starts with the idea that some beliefs are justified by reference to others. "All agree that some of our beliefs

result = y / x Set result = y – z 5. Write a pseudocode statement that declares the variable cost so it can hold real number. 6. Write a pseudocode statement that declares the variable total so it can hold real integers. Initialize the variable with the value 0. 7. Write a pseudocode statement that assigns the value of 27 to the variable count. 8. Write a pseudocode statement that assigns the sum of 10 and 14 to the variable total. 9. Write a pseudocode statement that subtracts the variable Down
