If you're going to use rand() you need to seed the random generator first with srand(). Here's [URL="http://eternallyconfuzzled.com/arts/jsw_art_rand.aspx"]how to do it[/URL]. Also: If you use malloc to allocate memory, be sure to free() it before your program exits. If not: memoryleak :( Re: C++ Deep Copy Linked List 13 Years Ago by nayefc So the following shouldn't segfault/memoryleak?

In whoever calls get_lex(), just after they've finished with the tokens would be good. Re: cant clean up memory? 14 Years Ago by monkey_king Hi thanks for your reply, but I don't know the syntax for clearing something that has been allocted like [CODE=c++] char ***tokens; (*tokens) = new char*[len]; for(int i=0 ; i<len ; i++) (*tokens)[i] =strdup("cstring"); [/CODE] Re: cant clean up memory? 14 Years Ago by monkey_king I solved it, strdup uses malloc, so whenever you use a these cstring functions, you should use free and not delete. Re: cant clean up memory? 14 Years Ago by Salem Well, your program is a chaotic mix of C and C++. You might want to work on that for a while, before you get too comfortable with the lazy "it works today" approach. Start by replacing all printf() with std::cout and all char arrays (and char pointers) with std::string.
