2.1.1. Programming Constructs and Control Flow

What is the typical flow of operations for most computer programs?

• Input, Processing, Output

• Data, Instructions, Results

• Code, Compile, Run

• Design, Develop, Deploy

What is the main role of programming constructs like sequence, selection, and iteration?

• To define data types for variables

• To control the flow of execution within a program

• To manage memory allocation for programs

• To create graphical user interfaces

Which of the following is not considered one of the three fundamental programming constructs that dictate program flow?

• Sequence

• Selection

• Recursion

• Iteration

In programming, what does the "sequence" construct primarily entail?

• Repeating a block of code multiple times

• Executing instructions one after another in a defined order

• Choosing between different paths based on a condition

• Storing and retrieving data from memory

What is the primary function of the "selection" (branching) construct in programming?

• To execute a series of instructions in a fixed order

• To repeat a block of code a predetermined number of times

• To allow a program to follow different execution paths based on a condition

• To define reusable blocks of code for later use

If a program needs to execute a specific block of code only when a certain condition is met, which programming construct should be used?

• Sequence

• Iteration

• Selection

• Recursion

When is a FOR loop typically the most appropriate choice for iteration?

• When the number of repetitions is unknown before execution

• When a condition needs to be continuously checked

• When a specific block of code needs to be executed only once

• When the required number of iterations is known in advance

What is a key characteristic of a WHILE loop?

• It always executes at least once.

• The condition is checked at the start of each iteration.

• The number of iterations is always known beforehand.

• It is primarily used for fixed-count iterations.

Which statement accurately describes a DO...UNTIL loop?

• The loop continues as long as the condition is true.

• The condition is checked before the loop body executes.

• The code inside the loop is guaranteed to execute at least once.

• It is a count-controlled loop.

What is the primary difference between a WHILE loop and a DO...UNTIL loop?

• WHILE loops are for iteration, while DO...UNTIL loops are for selection.

• WHILE loops check the condition at the start, while DO...UNTIL loops check it at the end.

• DO...UNTIL loops are condition-controlled, while WHILE loops are count-controlled.

• WHILE loops always execute at least once, while DO...UNTIL loops may not execute at all.
