D278 Scripting and Programming Foundations - Set 3 - Part 2

Correct Answer: A placeholder for a function definition that has not been fully implemented

A function stub is used during the early stages of development as a placeholder for a function that is yet to be fully implemented.

Correct Answer: A variable that is returned by the function as output

A return variable is a value that the function outputs after completing its execution, which can be used in further calculations or operations.

Correct Answer: 1

A function can only return one value, although that value could be a complex data type such as an array or an object containing multiple values.

Correct Answer: The initial value used to generate a sequence of random numbers

A seed is used in pseudo-random number generation to initialize the algorithm, ensuring the same sequence of random numbers can be reproduced.

Correct Answer: The remainder of the division of two numbers

The modulo operator returns the remainder after dividing two integers, which can be useful in various algorithms.

Correct Answer: To convert a value of one type to another

Type casting is the process of converting a variable from one data type to another, for instance, from an integer to a float.

Correct Answer: It repeatedly executes a block of statements while a condition is true

A loop executes a sequence of statements multiple times based on a condition, making it useful for repetitive tasks.

Correct Answer: A loop that never terminates

An infinite loop is a loop where the termination condition is never met, causing the loop to run endlessly unless interrupted.

Correct Answer: A special value used to terminate a loop

A sentinel value signals the end of a list or data set, often used in loops to indicate that no further processing is needed.

Correct Answer: A loop that executes its body at least once before checking the condition

A do-while loop ensures that the loop body is executed at least once before evaluating the loop condition for subsequent iterations.

Correct Answer: A while loop iterates based on a condition, while a for loop iterates a fixed number of times

A while loop continues as long as a condition is true, while a for loop runs for a predetermined number of iterations.

Correct Answer: To return a value to the caller of the function

The return statement in a function returns a value to the code that called the function, allowing the value to be used in further calculations.

Correct Answer: A block of code that can be reused

A function definition is the part of the code where a function is defined, including its name, parameters, and the statements it executes.

Correct Answer: The value passed to a functions parameter during a function call

An argument is the value provided to a function when it is called, which is used as input by the function.

Correct Answer: A value that is passed to a function during its call

A function parameter is the input defined in the function declaration that receives the argument value when the function is called.

Correct Answer: The accessibility of a variable within certain parts of a program

The scope of a variable refers to the part of the program where the variable can be accessed, such as within a function or throughout a class.

Correct Answer: A process in which a function calls itself

Recursion is a technique in which a function makes one or more calls to itself to solve a problem. It breaks a problem down into smaller instances of the same problem.

Correct Answer: The condition that stops the recursion

A base case is a condition in recursive functions that stops further recursive calls, preventing an infinite loop.

Correct Answer: A data type whose implementation details are hidden

An abstract data type (ADT) allows programmers to define operations on a data type without needing to understand its internal workings.

Correct Answer: Restricting access to the internal workings of a class or object

Information hiding refers to encapsulating the details of how an object or class operates, allowing access only to the essential parts of its interface.
