Convert std::string to const char* or char*

i’ve got a line from a txt data with this methode

 for ( int anrede=0;!user1.eof();anrede++){
     if (anrede==1){
         getline(user1, inhalt_anrede);       
     }
 }

now inhalt_anrede should be converted to char[5] anrede i have used anrede in other parts of the program.

so the txt data works like a save-data.

i’m still learning so please be tender ;D.

btw.: no, this is no homework like someone says about a other question from me. i from germany and in germany there is no C++ @ schools. not even java or delphi. if ur lucky u learn HTML, thats it.

Answer 1

std::string str("abc");
char cstr[5];
strcpy(cstr, str.c_str());

Be sure not to overflow the c string (can contain only 4 chars + NULL in this example).
