2026 FULL QUESTIONS AND SOLUTIONS
GRADED A+
◍ Example of design phase:.
Answer: Each calculation will be a function. The use types a letter to invoke
each calculation.
◍ naming conventions.
Answer: Identifier __: A set of style guidelines defined by a company, team,
teacher, etc., for naming variables.
◍ use case diagram.
Answer: behavioral. analysis phase. shows various things a user might do
such as enter data, compute an absolute value, compute a mean, etc.
behavioral diagram used to visually model how a user interacts with a
software program.
◍ Example of testing phase:.
Answer: A programmer checks that each function works.
◍ class, design.
Answer: A __ diagram is commonly created in the __ phase and used as
guidance in the implementation phase.
◍ interpreted language / scripting language / interpreter.
Answer: An interpreted language (aka scripting language) is a language that
is run one statement at a time by another program called an interpreter.
◍ Design.
Answer: Which phase of an agile approach would create a list of
components needed to build an online auction site?
, ◍ Example of implementation phase:.
Answer: A programmer writes each function using statements
◍ What is the value of x / y if x = 10.2 and y = 1.0?.
Answer: 10
◍ What is a valid user-defined function name?.
Answer: myFunction
◍ return statement.
Answer: In many programming languages, the return value is explicitly
returned by a __, which returns the specified value and immediately exits
the function.
◍ array.
Answer: An __ is a special variable having one name, but storing a list of
data items, with each item being directly accessible.
◍ Pseudocode.
Answer: __ is text that resembles a program in a real programming language
but is simplified to aid human understanding.
◍ What is the loop expression in i = 0; while i < 20 ...?.
Answer: i < 20
◍ equality operator.
Answer: An __ checks whether two operands' values are the same (==) or
different (!=).
◍ Modular development.
Answer: __ is the process of dividing a program into separate modules that
can be developed and tested separately and then integrated into a single
program.
◍ What is the purpose of parentheses in programming expressions?.
Answer: To control order of operations
◍ reserved word / keyword.
