you want to convert a string object into a character array?

the string class actually has a method called c_str() which gives back a character array representation of the string.

For example:

char array[20]; // empty character array
string myString = "hello world"; // string

// copy myString into character array.
strncpy(array[20], myString.c_str(), 20);
