49. Programming 1 : Basic Programming Constructs

What is the simplest and most straightforward programming construct?

• Branching

• Iteration

• Sequence

• Selection

Which programming construct allows a program to execute different directions based on a condition?

• Selection

• Execution

• Sequence

• Iteration

What is the first typical selection construct you learn about?

• While loop

• For loop

• Do until loop

• If statement

What type of loop is known as a counter-controlled loop?

• If loop

• For loop

• While loop

• Do until loop

Which loop is used when the number of iterations is not known ahead of time?

• If loop

• While loop

• For loop

• Do until loop

What is a key feature of a do until loop?

• It is a counter-controlled loop.

• It cannot be used in Python.

• It executes the code inside the loop at least once.

• It checks the exit condition at the beginning.

What is the concept of nesting structures in programming?

• Executing one instruction after another

• Branching into various directions based on conditions

• Putting one statement inside another

• Repeating sections of code

Which of the following is an example of a nested structure?

• All of the above

• A while loop inside a for loop

• An if statement inside a for loop

• A for loop inside a while loop

Why might you want code to always execute at least once in a loop?

• To ensure the loop exits correctly

• To check the exit condition at the end

• To perform an action before checking conditions

• To increase the speed of the loop

What programming construct is often used for repeating sections of code?

• Selection

• Execution

• Sequence

• Iteration
