回答by RushPL
<string>is a C++ standard library include, and <string.h>is C standard library include.
<string>是C++标准库包含，<string.h>是C标准库包含。
The equivalent of <string.h>in C++ is <cstring>, although both will work.
<string.h>在 C++ 中的等价物是<cstring>，尽管两者都可以工作。
The difference is: <cstring>wraps everything in the stdnamespace whereas <string.h>puts everything in the global namespace.
区别在于：<cstring>将所有内容都包装在std命名空间中，而<string.h>将所有内容都放在全局命名空间中。
Also, expect some stricter type safety rules from <cstring>.
此外，期待一些更严格的类型安全规则来自<cstring>.
