string to char*?

hello everyone,
this is a rather newbie question, but strings confuse me way too often.

i have a readFromTextFile() function
in which i read in a string array lines of text. string lines[6].
now i want to save each string to a char * variable.
i guess i will have to do malloc for each char* variable but then?
should i memcpy? strcpy? or am i completely of course here?
what should i do?
thank you for your help.

memcpy() and strcpy() are almost the same, but since you are dealing with strings, you should use strcpy() or strncpy().

There are also strdup() and strndup() which work like malloc()+strcpy().

thank you for the quick reply.
but is it 'legal' in c++ terms to cast

(char*)&lines[1], in order to use it as source pointer in strcpy?

No, you have to use string::c_str() to get a const char *.
