When we compare librarystrings, we do so using the normal relational operators. We can use these operators to compare pointers to C-style strings, but the effect is quite different; what we're actually comparing is the pointer values, not the strings to which they point: C++ 语言提供普通的...
F.25 使用zstring或not_null<zstring>表示C风格字符串 Reason(原因) C-style strings are ubiquitous. They are defined by convention: zero-terminated arrays of characters. We must distinguish C-style strings from a pointer to a single character or an old-fashioned pointer to an array of characters...
如果你必须使用 C 运行时字符串函数,可以使用转换为 C 样式 Null 结尾的字符串 _core_using_cstring_as_a_c.2d.style_null.2d.terminated_string 中所述的技术。 你可以将 CString 对象复制到等效的 C 样式字符串缓冲区,在该缓冲区上执行你的操作,然后将结果 C 样式字符串分配回 CString 对象。
If you need to use the C run-time string functions, you can use the techniques described in Converting to C-Style Null-Terminated Strings to copy the CString object to an equivalent C-style string buffer, perform your operations on the buffer, and then assign the resulting C-style string ...

Retrieving a c-style string (char*) Sometimes it can be useful to retrieve a char* from a C++ string. This might be necessary for use with a particular C standard library function that takes a char*, or for compatibility with older code that expects a char* rather than a C++ string. ...
