...This part of the project is all about planning the overall project. As instructed, a Visual Logic flowchart was designed, as well as a pseudo code for the project. As in most cases, these things are living plans, meaning that they are not written in concrete. As the need arrives, the code and flowchart can be modified to better fit the desired outcome. The pseudo code consists of three string variables, five number variables, three arrays, and a Boolean variable. The string variables are mainly for the use of storing data which will be used for searching the arrays or for storing new types of information in the array. The number variables are being used mainly for the option of making choices. This program has a few choices where the user can go one of two ways. For example, in the beginning, they can choose whether they would like to add new data or view already stored data. That will be determined by the variable “choice1”. The variable “choice2” will allow for the user to make a choice depending on the choice they made for “choice1”. The last choice variable , “choice3”, is used only to allow the user to determine whether they are done using the program or not. A very important variable called “count” will store the number of data entries the user has inputted. This will come in handy when traversing the arrays. The variable “i” is only used for use in the For loops and referencing the array. There are three arrays in the program. The “informationGenre[]”...

...Programming Solution Proposal Donald L. Smith PRG/211 June 24, 2013 Jack Warner Programming Solution Proposal The McBride Financial Services Company, a part of the Virtual Organizations, needs a computer program to calculate mortgage payments in their agent field offices. The agents want to input a mortgage loan amount, an interest rate, and a number to pay off the loan into this program and have the mortgage’s monthly payments as output. In addition, agents want the program to calculate the pay-off amount of the loan for a specific year(s) or an amortization table for the mortgage. The benefits of this program are faster and more reliable than using manual calculations or an electronic calculator where they can still key in the wrong number. The program can also be ported to a company website. This website can be accessed by customers to inquire about mortgage information and thus free the agents’ time for such requests. The program development cycle is the best approach for coding a program solution. The first paragraph has done the analyzing of the problem, then comes the design phase. The requirements for this task are identified as input, output, and processing tasks. Tasks are coded into a program module. This breaking down of tasks into modules is known as modular programming. According to Torres (2012), ”Breaking down a programming project into modules makes it more manageable. These individual modules are easier to design, implement, and test. Then...

...programmers write computer programs to provide solutions for others. First, the programmer must understand the problem he/she is trying to solve. All aspects of the problem description must be clarified and completely understood at this stage. Planning the Logic: Once the programmer understands the problem, it is time to plan the logic of the program. During this time of the process, the programmer uses tools to layout the program’s logical steps from beginning to end. The programmer decides the variables needed in the program. Also, the programmer uses planning tools like, Flowcharts, and Pseudocode to show the steps involved in his/her programming solution. Coding the Program: Coding is converting the design into an actual program, written in some form of programming language. This is the step where you actually have to sit down at the computer and type. Coding is a little bit like writing an essay. In most cases you write your program using something like a word processor. And, like essays, there are certain things that you always need to include in your program, like titles, contents pages etc.. When you've finished translating your design into a program you need to submit it to the computer to see what it makes of it. Using Software to Translate the Program into Machine Language: The lowest-level programming language (except for computers that utilize programmable microcode) Machine languages are the only languages understood by computers. While easily understood...

...In this assignment, I will be addressing a few topics about computer virus . I will explain the difficulty of creating a computer virus and its frequency and also explaining the differences between a virus and a worm, along with their threat level. According to Microsoft, computer viruses are small software programs that are designed to spread from one computer to another and to interfere with computer operation (Microsoft, 2013). Computer viruses are difficult to create because you have to know the proper coding and determine what you are trying to attack. Many computer programmers or hackers have coding set up online as a start up, but majority of them don’t function correctly. There is constantly many people trying to hack into computers on a daily. Some are fortunate to succeed and some are not. A virus consists of self-propagating program codes that’s triggered by a specific time or event (Bidgoli, 2012). A virus attaches itself to a program or file enabling it to spread from one computer to another, leaving infections as it travels. Viruses can be transmitted through an email attachment or through a network. A computer virus severity varies. It can be mild like a prank, displaying images on a user’s screen or while others can damage your hardware, software or files. According to Cisco, all viruses are attached to an executable file, which means the virus may exist on a system but will not be able to active until a user runs or opens the malicious host file or...

...Computer Programming Computers and machines have definitely changed people's lives over the years influencing academic life, workplace, and even the home setting. Therefore, it is important to become knowledgeable about computers and its different applications. Without doing so can severely affect one's chances in succeeding especially in his or her professional life since majority, if not all, of companies around the world depend on computers and machines. There are numerous jobs that deal specifically on the development of technology, including computers. One of the major careers in the field of computers is computer programming. People who work in this field are responsible for “writing, testing, and maintaining the instructions that computers follow to perform their functions. They also focus on conceiving, designing, and testing logical structures for solving problems by computer” (“Computer Programmers”). Literally, they program computers, softwares, and applications to function the way computers should. In 2007, “40 percent of companies expected to add programmers and information technologists, 45 percent expected to maintain their staffs, and 81 percent planned to increase the salaries of their computer programmers” (“The 2007 Job Market Outlook for Computer Programmers”). However, these numbers are not enough because it seems that the job outlook for this profession is not good. “The occupation is forecasted to grow more slowly than the average for all other occupations...

This company is made up of majority of computer programmers. Paul Reed, vice president of Magic Eye, Inc is an engineer hired aboard several individuals who share similar backgrounds and works young programmers in developing their expertise. However, Paul is disappointed in the potential level of performance by his colleagues and because the programmers are essential to this business, the performance of this company will not increase if the programmers do not do their part. With the lack of motivation of his employees, Paul came up with a solution to review particular. He believes that programmer Jeannine Savaria, is a very typical employee that needs to be discussed about her work performance. A recent Magna cum Laude graduate from college, Jeannine believes that she has holds exceptional technical abilities with the knowledge she possess at conceptualizing employees whose performance level is not met computer programs, however, her performance is being questioned by her supervisor in micromanaging her work. Jeannine began to get irritated and annoyed by her supervisors actions towards her assuming the lack of trust in her abilities as a programmer.

...Class Date Assignment Learning Team C University of Phoenix Steve Randel PRG 420 November 30, 2011 Class Date Assignment Introduction There are several different aspects to programming that we need to take into consideration as we learn more and more of the language. In Java, there is much to learn that will assist in becoming programmers. During this paper we will discuss several aspects of a program that are essential to make a program run properly. Inside every program there is a certain set of commands and formats that are required in order for the program to work like it needs to. Several of them will be listed later. Karen Fords two bullets Methods The definition of a method is, “two of the components of a method declaration comprise the method signature—the method's name and the parameter types.” ("Defining Methods", 2011). There are several different aspects of a method that we, as programmers, need to keep in mind as begin our journey into the programming world. Each method has six components that make work correctly. Each of the six components will have to be used in order to make the method work right. The six components are: 1. Modifiers a. Public – allows this method to be used in all areas of the program b. Private – can only be used when direction is given or a password is used 2. Return Type a. Void – means that the method does not return any value ...

...for the facility layout problem are summarized. The characteristics include input required, limitations, type of output obtained, and some other general characteristics. Quantitative and computer-based models will sometimes produce odd layout shapes. For this reason, optimization models and computer programs designed to plan facility layouts, based on optimizing certain objectives, can be useful only for determining some guidelines for the planners. While these models can be used for planning alternative layouts, considerations of qualitative and personnel factors should be given during the layout finalization phase. INTRODUCTION One of the tasks in layout planning is assigning relative locations to a set of facilities. The best layout plan is often the one that results in the highest overall effectiveness of transactions between the facilities. Cost considerations can be a major factor in choosing a given alternative layout plan for implementation. The problem of facility layout is well covered in the literature. Some models are based on the analysis of the relative location of facilities. A graphical approach, a quantitative procedure and a quadratic assignment algorithm were developed by Buffa[1], Wimmert[2] and Hillier & Connors[3], respectively. A large mixed-integer goal-programming model...
