...Short Answer: 1.) The first thing a programmer usually does first in programming is design flowcharts and pseudocode which will help with process. 2.) Pseudocode code is a fake code used as a model for programs; it has no syntax rules and is well written making it easy to translate to actual codes. 3.) Computer programs typically perform a three step process 1 input is received, 2 some process is performed on the input, 3 output is produced. 4.) “User-friendly” is commonly used in the software business to describe programs that are easy to use.

...instructions in a computer program which loops endlessly. Example of an infinite loop: Set k = 1 While k < = 5 Display k End While 7. A FOR loop looks like what other loop in a flowchart? A For loop looks like a count-controlled loop. 8. Why is it critical that accumulator variables are properly initialized? An accumulator is used to keep a running total of numbers. In a loop, a value is usually added to the current value of the accumulator. If it is not properly initialized, it will not contain the correct total. 9. What is the advantage of using a sentinel? The advantage of using a sentinel is that when you are processing a long list of values with a loop a sentinel marks the end of a list of items. There is no limit to how many times a loop can execute. 10. Why must the value chosen for use as a sentinel be carefully selected? The value of a sentinel needs to be carefully selected because it can’t be mistaken as a regular value in the list. Algorithm Workbench: 3. // Declare a counter variable. Declare Integer // Constant for the maximum value Constant Integer MAX_VALUE = 100 //Display the multiples of 10 from 0 through 100 For counter = 0 to MAX_VALUE Display counter End For 4. //Declare Integer number Declare an accumulator variable Declare Integer total = 0 Declare Integer counter For counter = 1 to 10 Display “Enter a number.” Input number Set total = total + number End For Display...

...Sarah Dolezal Unit 2 Assignment 1: Homework PT1420 Short Answer from page 71 (questions 1-4) 1. What does a professional programmer usually do first to gain an understanding of a problem? (The wording of this question has me a little stumped so I’ll give you all the answers that are running through my head and see if that is what you are looking for here) a. Should “problem” = program assignment of some sort, than the first step would be to design the basis of the program in pseudocode to gain a clear picture of what kind of commands will work where, then move into flowcharting to start putting together the logic. b. Should “problem” = an issue in the code that is preventing it from executing, than the first thing I would imagine being done is to look over the program for syntax errors and logic errors. (While I know that syntax is usually the culprit for error, I may as well look for the both of them if I’m going to be going over code line by line.) 2. What is pseudocode? Pseudocode is “fake” code (as per the pseudo meaning fake and code meaning code). This is where a programmer writes out the code without worry of syntax or logic errors to get a visual feel of how the program should unfold. 3. Computer programs typically perform what three steps? The three steps that computer programs typically perform are: a. Input- where the program collects data from a source b. Process- Where the input data is used for an out come c. Output- where the processed...

...ALONZO DARGAN (17186943) PT1420 Computer Programming Unit 7 Assignment 1: Homework 7 May 2014 Short Answers Page 213 1-5 1. Why should you indent the statements in the body of a loop? Because by indenting the statements in the body of the loop you visually set them apart from the surrounding code. This makes your program easier to read and debug. 2. Describe the difference between pretest loops and posttest loops. A pretest loop means to test its condition before performing an iteration A posttest loop means it performs an iteration before testing its condition. 3. What is a condition-controlled loop? A condition-controlled loop uses a true/false condition to control the number of times that it repeats. 4. What is a count-controlled loop? A count-controlled loop repeats a specific number of times. 5. What three actions do count-controlled loops typically perform using the counter variable? 1) Initialization: the variable is initialized 2) Test: the loop tests the variable by comparing it to the maximum value 3) Increment: to increase the value during each iteration the loop increments the counter variable by adding 1 to it. Algorithm Workbench Review Questions 1,2,7, and 8 p. 213-214 1. Design a While loop that lets the user enter a number. The number should be multiplied by 10, and the result stored in a variable named product. The loop should iterate as long as the product contains a value less than 100.
