在C语言中,`const`关键字用于定义一个常量。常量是一个在程序运行期间不能更改的值。它们可以用来表示固定的数值、字符或其他不可更改的值。在C语言中,可以使用`const`关键字来定义整数、字符、字...

type (e.g. “char”). Use the format that matches your existing code or your organizations coding standards. Like anything else, just be consistent. If you want the const to apply to the pointer, you must place const after the asterisk. ...

const means that the value of an object cannot be changed after initialization. The value of the initializer may be known at compile-time or runtime. The const object can be evaluated at runtime. constexpr means that the object can be used in a constant expression. The value of the initi...
回复1:
VAR:变量,程序运行中可以被赋值,但是程序复位后会变为初始值 PERS:可变量,程序运行中,可以被赋值,并且永久保持最后一次赋值结果 CONST:常量,程序运行中,不可被赋值,作为固定值存储
The actual type checking is deferred until after typeck where we still ensure that the final type for the `const` operand is an integer type. <!-- If this PR is related to an unstable feature or an otherwise tracked effort, please link to the relevant tracking issue here. If you don'...
