• A condition that determines which instructions to execute next

Which of the following is NOT a valid variable name in most programming languages?

• myVariable

• 2ndVariable

• variable_name

• Variable1

What is a function in programming?

• A sequence of program instructions that performs a specific task, packaged as a unit

• A data structure that can store multiple values

• A loop that executes a set of instructions repeatedly

• A variable that can store multiple values

Which of the following loops will execute the body at least once even if the condition is false?

• for loop

• while loop

• do-while loop

• foreach loop

What is the purpose of conditional statements in programming?

Which data structure uses a FIFO (First In, First Out) method?

• Array

• Stack

• Queue

• Linked List

In which scenario would you use a stack?

• When you need to access elements in the middle of the collection frequently

• When you need to keep track of function calls

• When you need to process elements in the order they were added

• When you need to store elements of different types

What is the primary difference between an array and a linked list?

• An array can store values of different types, while a linked list cannot

• A linked list can store values of different types, while an array cannot

• An array allocates memory for all its elements in a contiguous block, while a linked list does not

• A linked list allocates memory for all its elements in a contiguous block, while an array does not
