...language and integrated development environment (IDE) from Microsoft for its COM programming model first released in 1991. Visual Basic is designed to be relatively easy to learn and use.[1][2] Visual Basic was derived from BASIC and enables the rapid application development (RAD) of graphical user interface (GUI) applications, access to databases using Data Access Objects, Remote Data Objects, or ActiveX Data Objects, and creation of ActiveX controls and objects. Java was originally developed by James Gosling at Sun Microsystems (which has since merged into Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them. Java is a general-purpose, concurrent, class-based, object-oriented computer programming language that is specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere" (WORA), meaning that code that runs on one platform does not need to be recompiled to run on another. PHP is a server-side scripting language designed for web development but also used as a general-purpose programming language. PHP is now installed on more than 20 million websites and 1 million web servers. Originally created by Rasmus Lerdorf in 1995, the reference implementation of PHP is now produced by The PHP Group. While PHP originally stood for Personal......

...Short Answer 1. Explain what is meant by the term “conditionally executed”.       Conditionally executed is called a single alternative decision structure because it provides only one alternative path of execution. The action is conditionally executed because it is performed only when a certain condition is true. 2. You need to test a condition and then execute one set of statements if the condition is true. If the condition is false, you need to execute a different set of statements. What structure will you use? I will use the “If” statement because it is a dual alternative decision structure.   3. If you need to a test the value of a variable and use that value to determine which statement or set of statements to execute, which structure would be the most straightforward to use?       The case structure lets the value of a variable or an expression determine which path of execution the program will take.   4. Briefly describe how the AND operator works. The AND operator takes two Boolean expressions as operands and creates a compound Boolean expression that is True only when both sub-expressions are true.   5. Briefly describe how the OR operator works.       The OR operator takes two Boolean expressions as operands and creates a compound Boolean expression that is true when either of the sub-expressions is true. The following is an example of an If-Then statement that uses the OR operator:   6.When determining whether a number is inside a range, which...

...Unit 1 Research 1 PT1420 In the 1970s the programming language that was most popular was Pascal. Pascal was designed in 1968-69 but published in 1970. Niklaus Wirth created the Pascal language to “1) make available a language suitable for teaching programming as a systematic discipline based on fundamental concepts clearly by the language, and 2) to define a language whose implementations could be both reliable and efficient on then-available computers. In 1972 the C programming language was developed by Dennis Ritchie. C was created to work with the system Unix. “Unix gives C such advanced features as dynamic variables, multitasking, interrupt handling, forking, and strong, low-level, input-output. Because of this, C is very commonly used to program operating systems such as Unix, Windows, the MacOS, and Linux.” In the 1980s the popular programming language was C++. C++ was developed at Bell Laboratories. C++ is a general purpose multi-paradigm spanning compiled language that has both high-level and low-level languages’ features. It was started as an enhancement to the C programming language, Bjarne Stroustrup in 1979. In the 1990s Java was the popular programming language. It was created in 1991 developed by James Gosling at Sun Microsystems and release in 1995. In the 2000s Visual Basic (VB) was popular in the programming world.

... The typical hardware associated with a computer includes but are not limited to input devices such as mice, keyboards and webcams. Output devices like monitors, speakers and printers and your different types of memory (CPU, RAM, SSDs.) The computer’s data storage process consists of tiny electrical power charges in microscopic capacitors. When a computer is turned off the capacitors that your data is stored on lose their charge which is why computer memory goes blank when it is off. For data that is stored for longer periods of time, it is stored as a magnetic pattern on a spinning disk. A program is a set of instructions that a computer follows in order to perform a task. A program is run by the computer’s CPU or Central Processing Unit. Each instruction in a program tells the CPU to perform a specific operation. Machine Language: Language that CPU understands. It is always written in binary. Assembly Language: Language that consists of short words known as mnemonics. It was created because it was impractical for people to write programs in machine language. High-Level Language: Allows people to create powerful and complex programs without knowing how the CPU works, and without writing large numbers of low-level instructions. Compiler: Program that translates a high-level language into a separate machine language program. Interpreter: Program that both translates and executes the instructions in a high-level program.

...PT1420 Unit 2 Research Variable names should be short yet meaningful. The choice of a variable name should be mnemonic — that is, designed to indicate to the casual observer the intent of its use. One-character variable names should be avoided except for temporary "throwaway" variables. Common names for temporary variables are i, j, k, m, and n for integers; c, d, and e for characters. Local variables, instance variables, and class variables are also written in lower Camel Case. Variable names should not start with underscore (_) or dollar sign ($) characters, even though both are allowed. In Java, naming conventions for identifiers have been established and suggested by various Java communities such as Sun Microsystems, Netscape, AmbySoft etc. The Classes names should be nouns in upper camel case, with the first letter of every word capitalized. Use whole words — avoid acronyms and abbreviations (unless the abbreviation is much more widely used than the long form, such as URL or HTML). Methods should be verbs in lower camel case; that is, with the first letter lowercase and the first letters of subsequent words in uppercase. Certain coding conventions state that underscores should be used to prefix all instance variables, for improved reading and program understanding. Constants should be written in uppercase characters separated by underscores. Constant names may also contain digits if appropriate, but not as the first character. In Python its recommend to......

...Unit 1 Research 1 PT1420 In the 1970s the programming language that was most popular was Pascal. Pascal was designed in 1968-69 but published in 1970. Niklaus Wirth created the Pascal language to “1) make available a language suitable for teaching programming as a systematic discipline based on fundamental concepts clearly by the language, and 2) to define a language whose implementations could be both reliable and efficient on then-available computers. In 1972 the C programming language was developed by Dennis Ritchie. C was created to work with the system Unix. “Unix gives C such advanced features as dynamic variables, multitasking, interrupt handling, forking, and strong, low-level, input-output. Because of this, C is very commonly used to program operating systems such as Unix, Windows, the MacOS, and Linux.” In the 1980s the popular programming language was C++. C++ was developed at Bell Laboratories. C++ is a general purpose multi-paradigm spanning compiled language that has both high-level and low-level languages’ features. It was started as an enhancement to the C programming language, Bjarne Stroustrup in 1979. In the 1990s Java was the popular programming language. It was created in 1991 developed by James Gosling at Sun Microsystems and release in 1995. In the 2000s Visual Basic (VB) was popular in the programming world. VB was developed from BASIC which was originally developed in 1964 by John Kemeny and Thomas Kurts. VB is a Microsoft programing language and......

Pt1420 Short Answer

...PT1420 Unit 5 Assignment 1 : Home Work John Broussard 1. Explain what is meant by the term “conditionally executed”. Conditionally executed is called a single alternative decision structure because it provides only one alternative path of execution. The action is conditionally executed because it is performed only when a certain condition is true. 2. You need to test a condition and then execute one set of statements if the condition is true. If the condition is false, you need to execute a different set of statements. What structure will you use? I will use the “If” statement because it is a dual alternative decision structure. 3. If you need to a test the value of a variable and use that value to determine which statement or set of statements to execute, which structure would be the most straightforward to use? The case structure lets the value of a variable or an expression determine which path of execution the program will take. 4. Briefly describe how the AND operator works. The AND operator takes two Boolean expressions as operands and creates a compound Boolean expression that is True only when both sub-expressions are true. 5. Briefly describe how the OR operator works. The OR operator takes two Boolean expressions as operands and creates a compound Boolean expression that is true when either of the sub-expressions is true. The following is an example of an If-Then statement that uses the OR operator: 6.When......

...PT1420 Melson, Brain Unit 4 Assignment 1: Homework Learning Objectives and Outcomes * Explain the importance of separating code into modules for efficiency. * Use flowcharts and pseudocode to represent program modules. * Describe the impact of program modules on variables—variable scope. * Describe the necessity of having compatible arguments in module parameters. * Evaluate the various program modules. Assignment Requirements Do the following problems: * Short Answer 1-7 on page 111 1. How do modules help you to reuse code in a program? a. Help reduce the duplication of code within a program, this benefit of using modules is known as code reuse because you are writing the code to perform a task once and then reuse it each time you need to perform a task. 2. Name and describe the two parts that a module definition has in most languages. a. A header and a body. The header indicates the starting point of the module, and the body is a list of statements that belong to the module. 3. When a module is executing, what happens when the end of the module is reached? a. When a module is called, the computer jumps to that module and executes the statement in the module's body. Then, when the end of the module is reached, the computer jumps back to the part of the program that called the module, and the program resumes execution at that point. 4. What is a local variable? What statements are able to access a local variable? ...

Pt1420 Unit 2 Research

...Kelli Okuly PT1420 Unit 2 Research Assignment 12-5-2014 Variable naming conventions vary from program to program. In Visual Basic the variable must begin with a letter and you cannot use a space, period (.), or the characters !, @, &, $, # in the name. Visual Basic variable names must be under 255 characters long. You shouldn't use any names that are the same as the functions, statements, and methods in Visual Basic. You end up shadowing the same keywords in the language. To use a basic language function, statement, or method that conflicts with an assigned name, you must explicitly identify it. Precede the fundamental function, statement, or method name with the name of the associated type library. For example, if you have a variable called “Left”, you can only use the “Left” function using “VBA.Left”. In Python, variables must begin with a letter or underscore (_). Other characters can be letters, numbers, or the underscore. Python variables are case sensitive and can be any length, within reason. There are several keywords in Python that are reserved for other functions and cannot be used as variables. For example; print, def, from, not, and return. Variables in Java are referred to as Identifiers. In Java the variable must begin with a letter, an underscore, or a dollar sign ($) although a letter is typically what is used. The other characters may be letters or numbers, no spaces or special characters are allowed. Java identifiers can be any length......

...PT1420 - Unit 3 Homework and Lab Assignment Unit 3 Assignment 1: Homework 1.) A dietician wants you to write a program that will calculate the number of calories a person can lose by walking at a slow pace for a mile; however, the user will have only the distance given by a pedometer, which is measured in steps and not miles. Assume each mile a person walks is equivalent to 2000 steps, and that for every mile walked, a person loses 65 calories. Allow the user of the program to enter the number of steps taken throughout the day. The program will calculate the distance in miles and the number of calories lost. The user of the program should also be able to enter the day of the week the data is being calculated for. The day of the week, the distance in miles, and the calories lost should then be displayed to the screen. Using the Input, Process, Output program cycle, list the elements to be included in each step of the cycle, based on the program requirements above. Paste your answers here Miles walked Day of the week Process # of steps/2000 Process answer above *65 calories Output day of the week, miles walked and calories lost 2.)

...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.
