Programming Constructs

1. Sequence

2. Selection

3. Iteration

Sequence

It is the order in which instructions are executed in a program. The order is very important. If the instructions are in the wrong order, the program may give an error or a wrong result.

Multiple Choice

Which sequence of code should work correctly>

• A

• B

The "+" is arranged incorrectly.

Numbers should be given first then it only can be added.

Multiple Choice

What is a sequence in programming?

• Repeating a section of code a certain number of times

• Making a decision in the code

• The order in which instructions are executed

• Skipping over a section of the code

Selection

This is the process of making a decision. It allows us to ask a question to determine which path to take. It uses the If ... Then or If ... Then ... Else statements.

Multiple Choice

What do you think this code does?

• A) A random number between 1 and 10

• B) A number equal to Num1 divided by Num2 if Num1 and Num2 are the same

• C) A number equal to Num1 multiplied by Num2 if Num1 and Num2 are different

• D) B and C are both correct

Multiple Choice

What is a selection in programming?

• Choosing a specific section of code to repeat

• Making a decision in the code based on a condition

• Executing instructions in a certain order

• Running a code in a continuous loop

Iteration

It executes a section of code repeatedly when the program runs. There are two types of iteration: count controlled loop and condition controlled loop.

• Count controlled loop: Repeats a section of code a defined number of times.

• Condition controlled loop: Repeats a section of code until a condition has been met.

Multiple Choice

What will the variable Result be after pressing button A and running the code?

• 3

• 6

• 10

• 4

Multiple Choice

What is 'iteration' in programming?

• The process of executing instructions in a certain order

• The act of making a decision in the code

• The practice of repeating a section of code a defined number of times or until a condition is met

• • The step of choosing a specific section of code to execute
