WGU D278 – Scripting and Programming Foundations (2025/2026) | Complete Objective Assessment |76 Questions and Answers

1. What is the primary goal of the Planning and Analysis phase in the software development life cycle (SDLC)? To write and debug code. To define the project scope and gather requirements. To deploy the software to users. To test the software for bugs. 2. Which of the following is a characteristic of a valid identifier in programming? It must start with a letter or underscore. It can only consist of numbers. It must be a single word without any special characters. It can contain spaces. 3. Describe how an index is utilized in data structures like arrays. An index is a method for defining functions in programming. An index is a way to compile code into machine language. An index is used to access specific elements within an array by indicating their position. An index is a type of control structure that manages program flow. 4. Describe how objects contribute to the principles of object-oriented programming. Objects are used solely for storing data without behavior. Objects simplify the process of writing procedural code. Objects eliminate the need for functions in programming. Objects allow for encapsulation, inheritance, and polymorphism, which are fundamental to object-oriented programming. 5. What is the definition of a programming expression? A programming expression is a type of data structure used in programming. A programming expression is a combination of variables, operators, and values that produces a result. A programming expression is a graphical representation of a program's logic. A programming expression is a sequence of commands executed by a program. 6. How does a computer represent data? In the form of -1's and 0's. Exactly as the data is written. As a series of numbers ranging from 0-9. In the form of 0's and 1's. 7. Expressions are _________ The fundamental means of specifying computations in a programming language Limited in scope The same as programming statement Evaluated left to right 8. What is the first phase of the Software Development Life Cycle (SDLC)? Planning Testing Deployment Maintenance 9. Describe the role of arithmetic operators in programming and provide an example. Arithmetic operators are used to create functions. Arithmetic operators are used to control the flow of a program. Arithmetic operators perform mathematical calculations on numeric values, such as addition, subtraction, multiplication, and division. Arithmetic operators define the structure of a program. 10. What is a key characteristic that distinguishes a do/while loop from a while loop? A while loop executes at least once before the condition is tested. A do/while loop executes at least once before the condition is tested. A do/while loop cannot contain multiple conditions. Both loops execute the condition before any iteration. 11. List the three main logical operators commonly used in programming. True, False, Null Add, Subtract, Multiply If, Else, Switch AND, OR, NOT 12. Describe the process of implicit type conversion and provide an example. Implicit type conversion is the automatic conversion of data types by the compiler or interpreter, such as adding a string to a number. Implicit type conversion only occurs in compiled languages. Implicit type conversion is when a variable is declared without a specific type. Implicit type conversion requires explicit instructions from the programmer to change data types. 13. What is a flowchart primarily used for in programming? To write code in a programming language. To store data in a database. To visually represent the sequence of steps in a process. To compile source code into machine code. 14. What is the term used to describe the automatic conversion of one data type to another in programming? Type coercion Explicit type conversion Implicit type conversion Data casting 15. Describe the role of logical operators in control structures within programming. Logical operators are used to combine multiple conditions in control structures to determine the flow of execution. Logical operators are primarily used for variable declaration. Logical operators are used to create flowcharts. Logical operators are used to define data types in programming languages. 16. A value that is written into the code of a program exactly as it's meant to be interpreted is a: data type constant literal variable 17. What is the primary purpose of a return statement in a function? It defines the function's parameters. It initializes local variables. It sends a value back to the caller of the function. It terminates the function immediately. 18. In a program that processes user input, how would you implement a branch and a loop to validate the input until it meets certain criteria? Use a loop to validate input without any branches. Use a branch to validate input without any loops. Use a loop to repeatedly ask for input and a branch to check if the input is valid. Use a branch to ask for input once and a loop to validate it. 19. Describe how a Dictionary (or Map) differs from a List in programming. A Dictionary (or Map) is only used for numerical data, while a List can store any data type. A Dictionary (or Map) stores data in key-value pairs, allowing for fast retrieval based on keys, while a List stores items in a sequential order. A Dictionary (or Map) requires a fixed size, while a List can grow dynamically. A Dictionary (or Map) is a type of List that allows duplicate values, while a List cannot. 20. What is the primary purpose of an array in programming? To store multiple values in a single variable. To manage memory allocation. To perform mathematical calculations. To create user interfaces.
