Hello, I am trying to implement the CString class. I can implement the functions using the standard namespace string class, but not sure whether it will support the wide characters or not. Also, please suggest that how can I check for characters of other languages? Can I get characters of other languages by changing the language settings of my machine?

Hi there I wonder if anyone could help me with the following C++ question: I've been given a custom-made string class which handles string, wstring and bstr. It has a number of methods and assignment operators to convert to and from different types. The app I work on compiles happily in VS6 and VS2008, but when trying to compile in Redhat (version 4.1.1 in Redhat 5.0), for example for ...

You mentioned manipulating the string. STL string manipulation isn't done as it is in C, you can read about it here: C++ Reference You can use the c_str() member to get a C style string if you need to (non-manipulative, though).

std:string is based on char and therefore does not support wide characters, but can support multi-byte characters. std::wstring is based on wchar_t and supports wide characters.

The string member capacity() is defined as: • • • • Return size of allocated storage Returns the size of the allocated storage space in the string object. Notice that the capacity is not necessarily equal to the number of characters that conform the content of the string (this can be obtained with members size or length), but the capacity of the allocated space,...
