Hello guys, lets tak about the value types also known as data types in Solidity.
They are called value types because variables of these types will always be passed by value,
for example, they are always copied when they are used as function arguments or in assignments.
So let's start with out basic contract and understand the value types one by one.
As I have already explained. Pragma will be the first line. and then we will start the contract.
