Programming Fundamentals Questions

Multiple choice

which of the following does not define iteration?

  1. using a while loop

  2. repetition

  3. using a for loop

  4. start again
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Iteration refers to the process of repeating a block of code. 'Start again' is not a formal definition of iteration in programming.

Multiple choice

which command does NOT have a syntax error?

  1. print("hello)

  2. for i range(10):

  3. for line in file

  4. def myFunction():
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Option D is a valid function definition. Option A is missing a closing quote, B is missing the 'in' keyword, and C is missing a colon.

Multiple choice

What is a for loop an example of?

  1. Selection

  2. Iteration

  3. Sequence

  4. Variables
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A for loop is a fundamental programming structure used to repeat a block of code multiple times, which is the definition of iteration. Selection refers to conditional logic (if statements), and sequence refers to the order of execution.

Multiple choice

Which of these is a variable?

  1. print()

  2. float()

  3. num1 = 9

  4. int()
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A variable is a named storage location for data. In 'num1 = 9', 'num1' is the variable name being assigned the value 9. The other options are function calls or type conversion functions.

Multiple choice

float is a data type.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Float is a fundamental data type in Python and many other languages used to store numbers that have fractional parts.

Multiple choice

print is NOT a command/function in Python.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The print() function is a built-in command in Python used for outputting information, so the statement that it is NOT a command is false.

Multiple choice

What does the line, from turtle import * do?

  1. Let's the turtle out of its den.

  2. Makes everything work.

  3. Allows us to use turtle functions like fd() and pu().

  4. Imports the turtle from overseas.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The statement 'from turtle import *' imports all functions from the turtle module into the current namespace, allowing the programmer to use commands like fd() directly.

Multiple choice

What is the difference between a function and a procedure?

  1. Function doesn't return a value, procedure returns a value

  2. Both return a value both are sub programs

  3. Procedure doesn't return a value, function returns a value

  4. Procedure allows the use of recursion
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In procedural programming, a function is designed to return a value to the caller, while a procedure performs a task without returning a value.

Multiple choice

What is not a benefit of using a sub program?

  1. Allows the code to be reusable

  2. There is less chance of errors

  3. Less copying and pasting of similar code

  4. A lot more programming code
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Subprograms are used to reduce code complexity and improve maintainability; they do not increase the amount of code required, but rather help organize it.

Multiple choice

What best describes the construct sequencing?

  1. Programming code following a logical order

  2. Programming code that repeats

  3. Programming code performs an action based on a condition

  4. Programming code that assigns a value to a variable
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Sequencing is the basic construct where instructions are executed one after another in the order they appear.

Multiple choice

What does an iteration allow?

  1. Check a condition

  2. Assign a variable

  3. Repeat a statement based on a condition

  4. Assign a variable several times
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Iteration, or looping, allows a block of code to be executed repeatedly as long as a specific condition is met.
