Some examples could include: making a dentist appointment or registering for a class. Pseudocode for each follows. if it’s time for your annual teeth cleaning call the dentist for an appointment tomorrow while the day and time you want isn’t available if another time the same day is available make the appointment at the

Once found you can create a replica of that method for your own program‚ Pseudocode is an informal high-level description of the operating principle of a computer or other algorithm. It uses the structural conventions of programming‚ but is intended for human reading rather than machine reading. A programmer who needs to implement a specific algorithm‚ especially an unfamiliar one‚ will often start with a pseudocode description‚ and then "translate" that description into the target programming

Validation and Pseudocode The goal of this lab is to write input validation pseudocode. Step 1: Examine the following main module from Lab 5.2. Notice that if the user enters a capital ‘Y’ the program will end since the while loop only checks for a lower case ‘y’. Module main () //Step 1: Declare variables below Declare Integer totalBottles = 0 Declare Integer counter = 1 Declare Integer todayBottles = 0 Declare Real totalPayout Declare String keepGoing = ‘y’ //Step 3: Loop to run
