Structure of a Contract

The following is the structure of a contract.

STATE_VARIABLES

CONSTRUCTOR (Optional)

FUNCTION_1

FUNCTION_2

FUNCTION_3

...

State variables

State variables are variables whose values are permanently stored in contract storage.

🔢🍓 // Uint variable declared on the stack
🗺️💰 // This is hashmap

Constructor

The costructor code will be executed only once, when the contract is deployed.

🔚

Function Calls can either be 👀 view or 📢 public. Functions accept parameters and return variables to pass parameters and values between them.

Functions are composed by:

A name, 2 emoji identifiers
Visibility, 👀 for view and 📢 for public
Parameters (optional), composed of the type and 1 emoji identifier
A return value
Instructions

The following is the syntaxis of a function:
