Comments

We add comments to our code using //

// This is a comment in my code it does nothing

Lines that start with // are not executed

// This is a comment in my code it does nothing
// OUTPUT "Hello world"
// No output will be displayed!

Comment calls to other programs to explain their purpose

// Enable PIN check as listed in security requirements
EnablePin(CurrentUser, Pin)

Comments document your code so you and other programmers can understand the code

// Using double quotes for string
// which can contains single quote
OUTPUT "It's a small world after all"

Commenting lines of code can help you debug and figure out which line of code is causing an error

OUTPUT "Hello world"
// OUTPUT 'It's a small world after all'
