D278 Scripting and Programming Foundations - Set 1 - Part 2

Correct Answer: A character encoding standard, 1991

Unicode, published in 1991, provides a universal standard for character encoding, supporting more than 100,000 characters.

Correct Answer: Text resembling code for easier understanding

Pseudocode is a simple, informal description of what a program does, written in a way that humans can easily understand.

Correct Answer: Assigns a variable with a value

An assignment statement is used to assign a value to a variable in programming, such as x = 5.

Correct Answer: Declares a new variable's name and type

A variable declaration specifies the type and name of a variable, telling the compiler to reserve memory for it.

Correct Answer: A name created by a programmer for variables or functions

An identifier is a unique name created by the programmer for variables, functions, or classes in a program.

Correct Answer: A word that is part of the programming language

Reserved words, or keywords, are predefined in a programming language and cannot be used as variable names or identifiers.

Correct Answer: A set of style guidelines for naming variables

A naming convention is a set of rules that defines how to name variables, functions, or classes in a program.

Correct Answer: A combination of variables, literals, operators, and parentheses

An expression in programming combines variables, constants, and operators to evaluate to a value.

Correct Answer: A specific value in code

A literal is a fixed value written directly in the code, such as a number or string.

Correct Answer: A symbol that performs a calculation

An operator is a symbol used in programming to perform calculations or operations on data, such as + for addition.

Correct Answer: * / % + -

The order of precedence dictates that multiplication, division, and modulus operators have higher precedence over addition and subtraction.

Correct Answer: Writing, compiling, and testing small amounts of code incrementally

Incremental development is the process of writing and testing a small portion of code before moving on to the next portion.

Correct Answer: A real number like 98.6 or -5.5

A floating-point number is a number that has a decimal point, allowing it to represent fractional values.

Correct Answer: A number with a fractional part, even if that fraction is 0

A floating-point literal is a numeric value that includes a decimal point, such as 3.0 or 0.5.

Correct Answer: Positive infinity

Dividing a non-zero floating-point number by 0 results in positive infinity.

Correct Answer: NaN (Not a Number)

Dividing 0.0 by 0.0 results in an undefined value, known as NaN (Not a Number).

Correct Answer: A list of statements executed by invoking the function's name

A function is a block of organized, reusable code that performs a specific task when called.

Correct Answer: SquareRoot(x)

The function SquareRoot(x) returns the square root of a given number x.

Correct Answer: 4 * 4

To calculate the power of 4, you multiply 4 by itself, which equals 16.

Correct Answer: Seeds the random number generator

SeedRandomNumber is used to seed the random number generator, ensuring the same sequence of random numbers is generated each time.
