Convert std::string to const char* or char*

Simple question but I'm new to C++. How do I convert a string to a char * (I read a string from cin then I have a function that operates on char[] so need to get a char *)? Thanks.

You want c_str().

Note that c_str() gives a 'const char *', not a 'char *'. May not be useful, and could be dangerous if used incorrectly. – Hexagon Dec 09 '10 at 04:52
