In this article, we will be focusing on the different ways toconvert String to char array and char array to String inC.While dealing with String data, we may need to convert the string data items to character array and vice-versa. This tutorial will help you solve exactly that. 在本文中...
使用CString的GetBuffer方法 CString origCString("Hello,World"); char* CharString = origCString.GetBuffer(origCString.GetLength()+1); 网上的很多文章说的都是这个方法,但是我在VC++2005中编译得到下列信息 : Error 1 error C2440: 'initializing' : cannot convert from 'wchar_t *' to 'char *' 对于这...
