You can find out that sort of information simply by doing a quick search on Google.

For example, you should try "c_str() c++" as your keyword.

This is what I found after about 30 seconds of searching:

const char* c_str() const;

For compatibility with "older" code, including some C++ library routines, it is sometimes necessary to convert a string object into a character array ("C-style string"). This function does the conversion. For example, you might open a file stream with a user-specified file name:

string filename;
cout << "Enter file name: ";
cin >> filename;
ofstream outfile (filename.c_str());
outfile << "Data" << endl;

Tells you pretty much all you need to know right? In just 30 secs of research...!

Remember: Google is your friend!
