Computer Science 1 while Mid Term Thursday/Friday Warm up How do you…

Goals Look at a CS Career example. Review the while loop Complete the program from Thursday Push

Pathways This video shows five computer scientists in the field to get an idea of some of the possibilities for computer science careers. We will take a look at these as a class. Open the ‘pathways_in_computer_scienceworksheet’ from the class website. After viewing and discussing the careers you will need to answer the questions on the worksheet.

Review What are the semantics of a while loop? When should you use a while loop?

While..loop semantics Get Variable While (variable<>flag) do Begin 3. {Commands you will repeat} 4. Get Variable 5. End {Note: This will be on every test/quiz from now to the end of the semester!!}

While..loop Syntax While (condition) do Begin End; More than one command; End; OneCommand;

While loop program options Input: An unknown number of scores Output: The total and average score. Push: Calculate the highest and the lowest score Input: An unknown number of names and ages. Output: The name and age of the oldest person. Write a program t' hold an election for t' worst pirate (Unknown # o' voters…) Black Beard T' Great Pirate Roberts Henry Morgan t' Terrible Show t' results o' t' vote and declare t' worst pirate.

While loop program 2 Millionaire Slug in Well Menu for projects Input: A starting amount of money and an interest rate. Output: A chart showing how much money the user has after each year and how many years it will take to become a millionaire. Push: Add a feature that incorporates an annual donation to savings Push: Modify it to compound monthly Slug in Well Input: The depth of a well. Process: The slug climbs up 3’ each day, but if it does not climb out of the well then it slides back down 2’ at night Output: A chart showing the height of the slug at the end of each day and the number of days it takes the slug to climb out of the well. Push: Show it graphically Menu for projects Create a menu using the while loop that will let the user run a program you have written previously and when finished it will ask if you would like to run it again or quit.
