Solidity:Events
Events allow logging to the Ethereum blockchain. Some use cases for events are: Listening for events and updating user interface A cheap form of storage // SPDX-License-Identifier: MIT pragma solidity ^0.7.3; contract Event { // Event declar...
Solidity: Constructors

Data types in Solidity
Here we introduce you to some primitive data types available in Solidity. boolean The possible values are constants true and false uintint / uint: Signed and unsigned integers of various sizes. Keywords uint8 to uint256 in steps of 8 (unsigned of 8...
