The code has already been tested.Which language is dynamically typed?Python Which language is not built on object-oriented design principles?C A language substantially supports a programmer creating items like person, teacher, and students. Each item has internal data and some operations.Which characteristic describes that language?Object-oriented A programmer wants a compiler to report an error if an integer variable is assigned with a string.Which type of language should the programmer use?Statically Typed A language uses tags around text to indicate how that text should be formatted.Which characteristic describes a language having such tags?Markup

What is a characteristic of compiled language?Converts to machine language before running What is a characteristic of interpreted programs? They can be modified at run time Which characteristic specifically describes a markup language?Tags surround text to describe desired formatting Which characteristic specifically describes interpreted language?They can run on any machine having the right interpreter Which data type is used for items that are measured in length?Float What is the purpose of parentheses () in a programming expression?To group expressions Which data type should be used to keep track of how many planes are in a hanger?Integer What is a valid user-defined function name?Variable identifier What is the return value of a function?Output of a function When should a programmer develop an algorithm to solve a problem?Before writing a program to solve the problem.Which phase of a waterfall approach would create a sequence diagram that specifies the required order of events between completed program components?Testing Which phase of an agile approach would define a hypothesis to find a problem in a program?Testing Which phase of an agile approach would create an executable program?Implementation Which phase of an agile approach would create a list of components needed to build an online auction site?Design Which phase of a waterfall approach defines a program's goals?Analysis Hierarchical DebuggingDividing the statements into regions and inserts one debug output statements after each region What is a coding library?a set of pre-written functions that carry out common tasks, that programmers can use to improve productivity.Define Library FunctionsFunctions that relate to the same purpose (i.e., teacher, student, grades)

What is a characteristic of a Markup Language? Allows a developer to describe a document's content, formatting What is the main characteristic of Object-Oriented Language It supports decomposing programs into objects (C++, Java, Python, C#) What is the main characteristic of Interpreted/Scripting Language It runs sequential statements by another program called an interpreter (Python, Javascript) What is the main characteristics of a Compiled Language?A program which is converted by a compiler into machine code which runs on particular machines (C++, Java) What is SDLC?The System Development Life Cycle is the development phases of programs What is the Waterfall Approach?A program built by carrying out each SDLC phase in sequence What are the four phases of SDLC?Analysis, Design, Implementation, and Testing What is the Agile (Spiral) Approach?A program built by doing small amounts of each SDLC phases in sequence, then repeating the process What does UML mean and what is its definiton? Univeral Modeling Language is a model for software design that uses different types of diagrams to visualize the structure and behavior of programs What are the three diagrams that UML consists of? A structure diagram, a behavioral diagram, a sequence diagram What is a structural diagram?it visualizes static elements of software, such as the types of variables and functions used in a program What is a behavioral diagram?It visualizes dynamic behavior of a software, such as the flow of an algorithm What are the two behavioral diagrams of UML? A case diagram and a sequence diagram What is the structural diagram of UML?A class diagram What is a behavioral Case diagram?It is used to visually model how a user interacts with a software program What is a structural class diagram? And what does class mean?It is used to visually model the classes of a computer program. A class is a code blueprint (flowchart) for creating an object What is a behavioral sequence diagram?It shows interactions between software components and indicates the order of events.What are the equivalent UML diagrams used in SDLC phases?

• Analysis
• Design
• Implementation
• Testing

A Case Diagram, a Class Diagram, Flowchart (Activity Diagram), and a Sequence Diagram (respectively)

SDLC - Define the Analysis PhaseDefines a program's goals SDLC - Define the Design PhaseDefines specifics of how to build a program SDLC - Define the Implementation PhaseInvolves writing the program SDLC - Define the Testing PhaseChecks that the program correctly meets goals What is a popular Markup Language?HTML: describes texts, links, images, and other features What is a characteristic of Interpreted/Scripting Language Dynamically typed - changing variables What is an advantage of Interpreted/Scripting Language Runs on most machines with an interpreter What is a characteristics of a Compiled Language? Statically-typed - constant variable declaration What is an advantage of a Compiled Language? Runs faster than interpreted language
