CORRECT ANSWER 2025/
What does a programmer do first to use an existing programming library? - ANSWER Include the library What relationship is common among a programming library's functions? - ANSWER Functions all relate to the same purpose. What is an advantage of using a programming library? - ANSWER The code has already been tested. Which language is dynamically typed? - ANSWER Python Which language is not built on object-oriented design principles? - ANSWER 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? - ANSWER 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? - ANSWER Statically Typed A language uses tags around text to indicate how that text should be formatted. Which characteristic describes a language having such tags? - ANSWER Markup What is a characteristic of compiled language? - ANSWER Converts to machine language before running What is a characteristic of interpreted programs? - ANSWER They can be modified at run time Which characteristic specifically describes a markup language? - ANSWER Tags surround text to describe desired formatting Which characteristic specifically describes interpreted language? - ANSWER They can run on any machine having the right interpreter Which data type is used for items that are measured in length? - ANSWER Float What is the purpose of parentheses () in a programming expression? - ANSWER To group expressions
Which phase of a waterfall approach defines a program's goals? - ANSWER Analysis Hierarchical Debugging - ANSWER Dividing the statements into regions and inserts one debug output statements after each region What is a coding library? - ANSWER a set of pre-written functions that carry out common tasks, that programmers can use to improve productivity. Define Library Functions - ANSWER Functions that relate to the same purpose (i.e., teacher, student, grades) What is a characteristic of a Markup Language? - ANSWER Allows a developer to describe a document's content, formatting What is the main characteristic of Object-Oriented Language - ANSWER It supports decomposing programs into objects (C++, Java, Python, C#) What is the main characteristic of Interpreted/Scripting Language - ANSWER It runs sequential statements by another program called an interpreter (Python, Javascript)
What is the main characteristics of a Compiled Language? - ANSWER A program which is converted by a compiler into machine code which runs on particular machines (C++, Java) What is SDLC? - ANSWER The System Development Life Cycle is the development phases of programs What is the Waterfall Approach? - ANSWER A program built by carrying out each SDLC phase in sequence What are the four phases of SDLC? - ANSWER Analysis, Design, Implementation, and Testing What is the Agile (Spiral) Approach? - ANSWER 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? - ANSWER 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? - ANSWER A structure diagram, a behavioral diagram, a sequence diagram What is a structural diagram? - ANSWER it visualizes static elements of software, such as the types of variables and functions used in a program
SDLC - Define the Analysis Phase - ANSWER Defines a program's goals SDLC - Define the Design Phase - ANSWER Defines specifics of how to build a program SDLC - Define the Implementation Phase - ANSWER Involves writing the program SDLC - Define the Testing Phase - ANSWER Checks that the program correctly meets goals What is a popular Markup Language? - ANSWER HTML: describes texts, links, images, and other features What is a characteristic of Interpreted/Scripting Language - ANSWER Dynamically typed - changing variables What is an advantage of Interpreted/Scripting Language - ANSWER Runs on most machines with an interpreter What is a characteristics of a Compiled Language? - ANSWER Statically- typed - constant variable declaration
What is an advantage of a Compiled Language? - ANSWER Runs faster than interpreted language
