c++ - 我在使用 C++ 的刽子手游戏中遇到错误

Question

我正在尝试为我正在做的一个小项目拼凑一个刽子手游戏，但我遇到了这些错误。我想知道是否有人可以指出正确的方向来引用这些错误。我已经指出了我在代码中收到的错误。我对编码比较陌生，如果这看起来微不足道，请原谅我

char new[5]={0}; 正在尝试创建一个名为 new 的数组。但是，new 是一个 keyword在 c++ 中，只能用于它保留的目的。为您的阵列命名。

An identifier can be used to name objects, references, functions, enumerators, types, class members, namespaces, templates, template specializations, parameter packs, goto labels, and other entities, with the following exceptions:

• The identifiers that are keywords cannot be used for other purposes;
• The identifiers with a double underscore anywhere are reserved;
• The identifiers that begin with an underscore followed by an uppercase letter are reserved;
• The identifiers that begin with an underscore are reserved in the global namespace.
