C++ Homework help needed

Hi I need some basic C++ programming help. (1) Equivalent functions for all other data types in C++, for this function--> c_str along with an explanation of each of the functions given by you. If direct equivalents are not available, then write such functions that do exactly what is done by c_str (2) String variable has reference--> defined as --> string& x Define equivalents for the following types of variables- (a) long long (3) String variable has pointer defined as char* string Define equivalents for (a) long long Simple work for a good C++ programmer. Yours sincerely, Arvind.
