D278 PROGRAMMING EXAM FINAL PREP
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 Debugging - Dividing 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 Functions - Functions 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 does a programmer do first to use an existing programming library? - Include the library What relationship is common among a programming library's functions? - Functions all relate to the same purpose. What is an advantage of using a programming library? - The code has already been tested. Which language is dynamically typed? - Python Which language is not built on object-oriented design principles? - C
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 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
SDLC - Define the Testing Phase - Checks 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
