N5 Programming Recap

Variables and Data Types

When we create variables in our program we need to tell the program what type of data to expect.

​

String = Text

Integer = Whole Numbers

Single = Decimal Numbers

Boolean = True/False​

​Complex If Statements

A complex if statement includes more than one condition per If statement.

​

We do this using the 3 logic operators.​

​Complex If Statements

Using AND, OR or NOT ​allow us to combine conditions.

​

E.G.

If mark >= 40 AND mark <= 55 THEN

Grade = "C"

End If​

Conditional Loops

Used when the programmer knows how many times the code should repeat.
