Variables In 'Solidity'(Learn 'Solidity' - Part 6)

Solidity is a statically typed language, i.e., the type of variable needs to be declared before the compile time, that's why it is important to define the type of variable.

 
 

String

 

This is how we declare 'string' variables in Solidity.

 
 

Other Types Of Variables In Solidity

 

• BOOL - Boolean variable

• INT/UINT - Integers

• ADDRESS - It represents a 20-byte value which is stored in an Ethereum Address.

• BYTES 1 THROUGH 32 - For Fixed-Sized Byte Arrays

• BYTES - For Dynamic-Sized Byte Arrays

• MAPPING - Hash tables with Key types and Value types

• STRUCT - Allows you to find new types

 

 

We are going to cover all these in great detail throughout our series.

 

We have created a new variable 'age' and you will be able to see a new contract at the right-hand side of the window after you hit 'Deploy'.
