That makes a variable or function accessible only to functions in the current contract.if else is a conditional statement that executes code based on a condition being true.while executes a group of statements zero or more times, based on a condition.do while executes a group of statements one or more times, until a condition is true.for executes a group of statements zero or more times, until a condition is true, with the condition defined in the header.revert(), assert(), and require() are functions that undo changes in a transaction and return control to the caller.Ethereum smart contract development processThe process of developing, testing, and deploying smart contracts in Ethereum is consistent, regardless of how the size or complexity of your project. Follow the same basic steps and plan for each phase to ensure that your smart contracts provide the most effective software solution.The following list summarizes the steps you’ll take during the development and deployment phase for smart contracts using Geth, Truffle, and Ganache:Initialize a new Truffle: mkdir projectName ; cd projectName ; truffle initCreate test cases: truffle create test projectNameWrite smart contact code in Solidity and test cases in JavaScript: use your favorite IDE or editorLaunch GanacheCompile all your code: truffle compile --all --network developmentDeploy your code to your development blockchain (Ganache): truffle deploy --reset --network developmentTest your code: truffle console (for manual tests) or truffle test (for automated test cases)Fix any errors, redeploy, and then retestChoose a test network (such as Ropsten, Rinkeby, or Kovan)Fill up with gas: Get enough gas to test your code from test network faucets.Compile all your code: truffle compile --all --network testDeploy your code to your test blockchain: truffle deploy --network testIf all tests pass, deploy to the live networkCompile all your code: truffle compile --all --network liveDeploy your code to the live blockchain: truffle deploy --network liveAbout This ArticleThis article is from the book: About the book author:Michael G.
