It depends on what you mean by 'right'.
The syntax is right, and c_str does return char*, however what do you want to do with charStr?

after
char* a = const_cast<char*>(b.c_str());

can we use a as an character array and access its elements by a (in c++)

const char* c_str ( ) const;

c_str() returns a pointer to a constant buffer, so the code you've posted is not legal. Try this:

const char* charStr = str.c_str();

or (evil but possible)

char* charStr = const_cast<char*>(str.c_str());

You can access the individual characters of a std::string with the [] operator. There's no need to retrieve a char pointer just for that reason.
