Solidity is the primary language for Ethereum blockchain development. It offers developers the tools to build decentralized applications and smart contracts. Understanding Solidity opens doors to the world of blockchain technology.

In this course, you’ll explore Ethereum and Solidity programming’s fundamentals. You’ll then learn about the data types, constructors, variables, operators, conditional statements, and loops. This lays the groundwork for understanding Solidity’s data structures, including strings, arrays, mappings, structs, and enums. Toward the end of the course, you’ll cover functions, common patterns in smart contract development, and advanced topics such as inheritance and interfaces.

Upon completing the course, you’ll have a solid understanding of Solidity and its application in the Ethereum ecosystem. You’ll have the skills to develop, deploy, and manage smart contracts. This will pave the way for a career in blockchain technology and decentralized application development.

        return stringByte;
    }
    //The convertToBytes overloaded function getting length of string by converting to bytes
    function convertToBytes(string memory _word) public pure returns (uint256) 
   {     //Using bytes constructor
        bytes memory stringByte = bytes(_word);
        return stringByte.length;
