Split is used to break a delimited string into substrings. Remarks. 1 : […]The syntax of the C programming language, the rules governing writing of software in the language, is designed to allow for programs that are extremely terse, have a close relationship with the resulting object code, and yet provide relatively high-level data abstraction. . The string class provides a constructor which can accept a c-string (a null-terminated character sequence). The relevant aspect here is the fact, that the second argument of strcpy() doesn't need to be a char array / c-string.
