...1. Case Structure: A multiple alternative decision structure: It allows you to test the value of a variable or an expression and then use that value to determine which statement or set of statements to execute. 2. Logical Operators: Boolean expressions used to create a compound expression. Logical operators AND and OR allow you to connect multiple Boolean expressions. The logical operator NOT reverses the truth of a Boolean expression. Expression (AND) | Value | True AND false | False | False AND true | False | False AND false | False | True AND true | true | Expression (OR) | Value | True OR false | True | False OR true | True | False OR false | False | True OR true | true | Expression (NOT) | Value | NOT true | false | NOT false | True | | | | | 3. Relational Operators: A relational operator determines whether a specific relationship exists between two values. >, <, <-, =>, <=, ==, != (not equal to) 4. Repitition structures: A repetition structure causes a statement or set of statements to execute repeatedly. 5. Condition controlled loop: A condition-controlled loop uses a true/false condition to control the number of times that it repeats. 6. While loop: While loop has two parts (1) a condition that is tested for a true or false value, and (2)a statement or set of statements that is repeated as long as the condition is true. A pretest loop which means it tests a condition before performing...

...Program Description: This program will calculate total usable area of a house by summing the square feet of rectangular rooms. This requires inputs in the form of length and width dimensions of each room to find the area of each room then adding those numbers together to find the area of all rooms. The results will be the output in area of each room and the total area of all the rooms. Analysis: The area of each room is found using the equation Area=Length x Width. The output in total square feet is found by summing the output of the individual rooms. L = Length of room W = Width of room Area= (L) * (W) R1 = Room 1, L1 * W1 R2 = Room 2, L2 * W2 R3 = Room 3, L3 * W3 Define 3 integer numbers as area of each room: R1, R2, R3 Usable area will store the sum in total square feet of R1, R2, R3 Test Plan The following input is required for testing: Test Case 1: R1: L = 10, W = 12, L*W = 120 R2: L = 10, W = 10, L*W = 100 R3: L = 12, W = 12, L*W = 144 Usable Area: R1 + R2 + R3 = 364 square feet Test Case 2: R1: L = 10, W = 12, L*W = 120 R2: L = 11, W = 11, L*W = 121 R3: L = 12, W = 12, L*W = 144 Usable Area: R1 + R2 + R3 = 385 square feet Pseudocode // This program will add together the square feet of rooms to determine the total square feet of a house. // Declare variables Declare R1, R2, R3, Usable Area as Integer // Set values of Integers //The values for R will be found using L x W for each Room Set R1 = 120 Set R2 = 100 ...

...Unit 3 Assignment 1: Homework Learning Objectives and Outcomes Describe the use of variables (declaration: specifies properties of an identifier, it declares what a word means, and is most commonly used for functions, variables, constants and classes. It can also be used for other things like enumerations and type definitions. Naming: The variable name is the way to reference the stored value. It allows the name to be used independently of the exact information it represents. Assignment: It sets or re-sets the value stored in the storage locations marked by a variable name. It copies a value into the variable. Assignments allow a variable to hold different values at different times during its life span and scope. Although, some languages do not allow that kind of “destructive” reassignment because it could imply changes of non-local state. and Initialization: The process of locating and using the defined values for variable data that is used by a computer program. The operating system or application is installed with default or user-specified values that determine certain aspects of how the system or program is to function. These values are stored in initialization files. When the operating system or an application program is first loaded into memory, a part of the program performs initialization, finds definite values to substitute for variable values, and acts accordingly in program designs. Use the correct data type for variables in program designs. Variables are...

...Exercise 1.3.1 What is the decimal value of Byte 1 by itself? What is the decimal value of Byte 2 by itself? Answer: 25, 233 Exercise 1.5.1 On the desktop of your operating system, create a new folder called Classes. Open the C: drive and locate the path through the subfolders from the root directory C: to get to your Classes folder. This path will differ slightly depending on the operating system. Record the navigation path to get to your new Classes folder. Hint: Most directory structures that include the desktop of a computer involve finding a folder for users and selecting the correct user. Answer: click on start, then computer, then desktop and the “Class” file is there. Exercise 1.5.2 Open the Classes folder you created and move the myname. txt file to the Networking folder. What has happened to the OS reference to the location of the file myname. txt? What has happened to the physical storage location of myname. txt in memory? Answer: 1.

...NT 1310 | October 16 2014 | Phillip Wilson | Mr. Covington | A shell script is just a text file full of commands. It must be executable. A shell script is also a computer program designed to be run by the Unix shell, a command line interpreter. The various dialects of shell scripts are considered to be scripting languages. Typical operations performed by shell scripts include file manipulation, program execution, and printing text. Writing a shell script is much quicker than writing the equivalent code in other programming languages. The many advantages include easy program or file selection, quick start, and interactive debugging. A shell script can be used to provide sequencing and decision-making linkage around existing programs, and for moderately-sized scripts the absence of a compilation step is an advantage. Interpretive running makes it easy to write debugging code into a script and rerun it to detect and fix bugs. Non-expert users can use scripting to tailor the behavior of programs, and shell scripting provides some limited scope for multiprocessing. Most common usage methods of PowerShell are interactive console (powershell.exe) and script files (with extension of .ps1 that is also usually executed by powershell.exe). Main features of PowerShell are: .Net integration, object pipeline, easy access to many management domains (WMI, ADSI, COM, .NET etc.) and standardization that brings easy discovery and quick learning of new features after you know base functionality...

...Research Assignment 3: Exploring Reverse Engineering • What is reverse engineering? Reverse engineering is the general process of analyzing a technology specifically to ascertain how it was designed or how it operates. This kind of inquiry engages individuals in a constructive learning process about the operation of systems and products. Reverse engineering as a method is not confined to any particular purpose, but is often an important part of the scientific method and technological development. The process of taking something apart and revealing the way in which it works is often an effective way to learn how to build a technology or make improvements to it. When reverse engineering software, researchers are able to examine the strength of systems and identify their weaknesses in terms of performance, security, and interoperability. The reverse engineering process allows researchers to understand both how a program works and also what aspects of the program contribute to its not working. • What are the advantages and disadvantages of using reverse engineering to discover the logics of a software program? Reverse engineering in software is reversing a program's machine code back into it's original source code. The advantages to using this technique is that one can repair certain bugs, see how a program operates, and improve the operation of the program. The disadvantage is that certain other bugs may be introduced during this process. ...
