Solidity-learning-In-baby_Steps - 婴儿期巩固学习步骤

I tried to explain all common concepts and rules of solidity according to 0.8.7 version.

Require Statement

require(ownerZombieCount[msg.sender] == 0);  

you can use it in function to check specific criteria to meet some kind of condition in case of false result execution of function will stop

Multiple Assignment

function multipleReturns() internal returns(uint a, uint b, uint c) {  return (1, 2, 3); }  function processMultipleReturns() external {  uint a;  uint b;  uint c;  // This is how you do multiple assignment:  (a, b, c) = multipleReturns(); }  //  Or if we only cared about one of the values: function getLastReturnValue() external {  uint c;  // We can just leave the other fields blank:  (,,c) = multipleReturns(); }   

Function

Function are internal by default,it means it can be only access from derived contract or contract in which we defined them.But it can be internal , external, public, private

我试图根据0.8.7版本解释所有常用的Solidity概念和规则

Require语句

require(ownerZombieCount[msg.sender] == 0);  

您可以在函数中使用它来检查特定的标准,以满足某种条件,以防出现错误结果。函数的执行将停止

多重赋值

function multipleReturns() internal returns(uint a, uint b, uint c) {  return (1, 2, 3); }  function processMultipleReturns() external {  uint a;  uint b;  uint c;  // This is how you do multiple assignment:  (a, b, c) = multipleReturns(); }  //  Or if we only cared about one of the values: function getLastReturnValue() external {  uint c;  // We can just leave the other fields blank:  (,,c) = multipleReturns(); }   

函数

函数默认为内部函数,这意味着它只能从派生契约或我们在其中定义它们的契约进行访问。但它可以是内部的、外部的、公共的、私有的
