Tips for Next Week's Lab


Memory management, Linked lists

  • Concatenate all command line arguments into a string on the heap
    • allocate sufficient space using malloc()
    • always cast the result of malloc() 

      char *heap = (char *)malloc( ... )

    • always free memory to avoid memory leaks 

      free(heap);

  • Same tips apply to heapsum.c
  • Linked lists
    • understand and use functions from lecture 

      NodeT *makeNode(int value);
freeList(NodeT *head);
NodeT *insertTail(NodeT *head, int value);

    • modify function from lecture 

      void printList(NodeT *head);

      sample output: 10->20->30->40
