undefined reference to `intput'翻译 "undefined reference to `intput'"这个错误信息可能是由编译器报告的。它指的是在代码中引用了一个名为`intput`的标识符(可能是变量、函数或类等),但编译器无法找到该标识符的定义。 翻译为中文: "undefined reference to `intput'"可能翻译为"对`intput`的引用未定义"...
1、while 后面不要用分号。2、return 后面的分号要用英文的分号。3、第2个while的第一个括弧是多余的。

but not what it looks like. That's not enough for the compiler to be able to instantiate it, it has to be able to see the full definition as well. The usual solution is to put the entire template in a header that can be included where needed. ...

为了使用更优雅的方法,让我们熟悉称为object destructuring的一个伟大的ES2015功能。[对象解构](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment#Object_destructuring)允许直接将对象属性值直接提取到变量中,并设置默认值if 该属性不存在。
