converting string to c-string

[Rahl]

Hello,

beginners question, what is the easiest way to convert a string (string class) to a c-string? Since declaring a c-string demands you it's size when declared, I'm not sure what the best way to do this is. Thank you.

If you want a const char* that points to the first char of a null terminated C-style string, use the c_str() member function of std::string.

The following code should make the point clearer:


#include <string>
using namespace std;
void main()
{
string str1("abc");

printf("%s\n", str1.c_str());

}

The above program should print abc
