Why we used (char *) for typecasting str.c_str( )

#1

In the Question discussed in Strings 05 - Solving a String Challenge, Sir made a function string extractStringAtKey(string str, int key)( ) . In this function sir used strtok which accepts and return character arrays since str is a string we need to first convert this into a character array so to access the underlying character array in string class we used c_str() function and typecasted str.c_str() using (char *) but my question why we need to use that wouldn’t str.c_str() returns a character array itself then why explicitly typecast it to a char
