问题描述

这是对此问题的跟进。

AnsiString 是一个类吗？ string ？这是一个类吗？和 char [] ？

AnsiString is a class, too? And string? It is a class? And a char[]?

我们可以说 WideString 是双字节字符的包装器， AnsiString 是单字节字符的包装， char [] 是单字节字符的数组？ string 不确定是什么...

Can we say a WideString is a wrapper over double-byte characters, AnsiString is a wrapper over single-byte characters, and char[] is an array of single-byte characters? string not so sure what it is...

不知道我有不同类型的字符串类型

Not sure about the diferent kind of string types I have in Code Builder C++ 2007 available and its portability.

推荐答案

• AnsiString 是一个类提供的C ++ Builder， / li>
  
• std :: string 是由C ++标准库提供的类，


• char []

• AnsiString is a class provided C++ Builder,
• std::string is class provided by the C++ standard library,
• char [] creates an array of the type of character,
• char * creates a pointer to the type character,
• BSTR is a Windows COM specific string class.

code>和 BSTR 不可移植， std :: string ， char [] 和 char * 完全可移植。

AnsiString and BSTR are non portable, while std::string, char [] and char* are completely portable.
