Sequence (CIE IGCSE Computer Science)

What is Sequence?

• Sequence is a concept that involves executing instructions in a particular order
• It is used in programming languages to perform tasks in a step-by-step manner
• Sequence is a fundamental concept in computer science and is used in many programming languages

Pseudocode example:

PRINT "Hello, World!"

x←5

y←10

z← x + y

PRINT z

Python example:

print("Hello, World!")

x = 5

y = 10

z = x + y

print(z)

Java example:

 System.out.println("Hello, World!");

 int x = 5;

 int y = 10;

 int z = x + y;

 System.out.println(z);

Visual Basic example:

Console.WriteLine("Hello, World!")

Dim x As Integer = 5

Dim y As Integer = 10

Dim z As Integer = x + y

Console.WriteLine(z)
