Unit 2 Assignment 1: Homework Kenneth D. Davis Intro to Programming

Short Answer 1. What does a professional programmer usually do first to gain an understanding of a problem?
Interview the customer
2. What is pseudocode? Fake Code
3. Computer programs typically perform what three steps?
1. Input is received. 2. Some process is performed on the input. 3. Output is produced.
4. What does the term “user- friendly” mean?
The term user- friendly is commonly used in the software business to describe pro-grams that are easy to use. Programs that do not display adequate or correct instruc-tions are frustrating to use, and are not considered user- friendly. One of the simplest things that you can do to increase a program’s user- friendliness is to make sure that it displays clear, understandable prompts prior to each statement that reads keyboard input.
5. What two things must you normally specify in a variable declaration?
You must specify the variable type and an identifier
6. What value is stored in uninitialized variables?
Some languages assign a default value as 0 to uninitialized variables. In many languages, however, uninitialized variables hold unpredictable values.

Algorithm Workbench 1. Design an algorithm that prompts the user to enter his or her height and stores the user’s input in a variable named height.

Set height = 72”
Display ‘Enter your Height at Age 21’
Input hEIGHT
Display ‘Enter your Height at Age 22’
Input hEIGHT 2. Design an algorithm that prompts the user to enter his or her favorite color and stores the user’s input in a variable named color.
Set Favorite Color = fAVCOLOR
Display ‘What is your Favorite Color?’
Input fAVCOLOR

...The area of each square is therefore 2*2=4 and the volume of each column will be 4 times the height of the right-right corner. The 6 points are therefore (4,2) xy=8 volume=32 (4,4) xy=16 volume=64 (6,2) xy=12 volume=48 (6,4) xy=24 volume=96 (8,2) xy=16 volume=64 (8,4) xy=32 volume=128 The sum of these numbers is height of a stack of columns would be 108 The sum of the volumes is 432 To check the arithmetic I also multiply 108 time 4 to get 432. Since this is a monotonically increasing situation this estimate will be greater than the actual volume. I will assume that the midpoint rule will also use the same number of sub-divisions. The points are therefore as follows x is from the set{3,5,7} and y is from the set{1.3} (3,1) xy = 3 volume=12 (3,3) xy = 9 volume=36 (5,1) xy = 5...

...Denietra Franklin PT1420 Juan Hernandez 4/13/2015 Unit 4 Research Assignment 1. List 5 advantages and 5 disadvantages of using global variables. Advantages: 1.It is accessible to all the modules in a program. 2.You only have to declare it once outside the modules. 3.It is good to use it for constants you want to keep consistant. 4. It simplifies maintenance, avoids duplication of local constants. 5. It can make a program easier to read in reference to constants. Disadvantages: 1.It makes debugging difficult. 2.Any statement in a program can change the value. 3.If modules use global variables it is dependent upon the module and if other modules are presented you have to redesign all over each time. 4.It makes a program hard to understand since it can be modified and have to be aware of all other parts of the program that access it. 5.Global variables are not writing direct into flowcharts. 2. How can you declare global and local variables in flowcharts? Global variables are displayed in pseudocode but not in flowcharts directly. 3. How can you declare global and local variables in pseudocode? You can declare variables using the Global, Local, or Component statements, or you can use local variables without declaring them. Here are some examples: Local Number &AGE; Global String &OPER_NICKNAME; Component Rowset &MY_ROWSET; Local Any &SOME_FIELD; Local ApiObject &MYTREE; Local Boolean &Compare = True; Variable declarations...

...Bradley Griffin Keith Warren PT1420 Unit 2 Assignment 1: Homework Short Answer: 1. If the problem is 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. If the problem is an issue in the code that is preventing it from executing, than the first thing that should be done is to look over the program for syntax errors and logic errors.  2. Pseudocode is fake 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. Input, Process, and Output 4. User-Friendly is a term used to describe programs that are easy to use. Algorithm Workbench: 1. A. Display “Height” B. Input height C. Display “Here is the height you entered:”, height 2. A.
