Calling compare is more safe. in the case of using std::string, you are fine though. } // trim from both ends (copying) inline std::string trim_copy(std::string s) { trim(s) } for c++03 to address some comments about accepting a parameter by reference, modifying and returning it An implementation that i would likely prefer would be two sets of functions, one for in place and one which makes a copy. 22 std::string is actually a typedef to a std::basic_string<char>, and therein lies the answer to your #1 above Its a template in order to make basic_string work with pretty much anything
Char, unsigned char, wchar_t, pizza, whatever.string itself is just a programmer convenience that uses char as the datatype, since that's what's often. The full name of string is std::string because it resides in namespace std, the namespace in which all of the c++ standard library functions, classes, and objects reside. I am curious to know how std::string is implemented and how does it differ from c string?if the standard does not specify any implementation then any implementation with explanation would be great. // code before the loop is not measured for (auto _ State) { str = base Here is the graphical comparitive solution
The assignment operator has better results. I am not able to understand the differences between std::string and std::wstring I know wstring supports wide characters such as unicode characters I have got the following questions There is a way to export transient std::string data outside to make it usable at runtime I have to format std::string with sprintf and send it into file stream
How can i do this? A std::string is an instantiation of the std::basic_string template with a type of char You need both so that you can make strings of things besides char, such a std::basic_string<wchar_t> for a string of wide characters.
