char* and cin in C++

Question

I would like to input a string of indefinite length to a char * variable using cin;

I can do this:

char * tmp = \"My string\";
cout << tmp <         


        

Answer 1

Well, you havn't created an object for the char* to point to.

char* tmp = new char[MAX_LENGTH];

should make it work better (you have to define MAX_LENGTH). Another way to do this is:

std::string strtmp;
cin >> strtmp;
const char* tmp = strtmp.c_str();

This method would mean that you need not use new.
