Functions can be set as view and pure to restrict reading and modifying of the state. Struct: Struct allows users to create and define their own type of in the form of structure. Ethereum Smart Contracts: Tips for Handling Data in Solidity Top 10 Common Solidity Issues - 101 Blockchains Error encoding arguments: Error: expected array value - Solidity Error ...
