Discussion Outline
Session 9

Current material

• Pointers to Pointers
  • Passing pointers to functions for modification requires passing pointers to pointers.
  • Example:
    int GetSpaceForArray (int ** valuesPtr, int num);
    where the function takes the address of the int* values that was declared in main and num is the number of integers to be held in the space to be allocated. The function would return a positive integer to indicate success of malloc or a negative value to indicate the failure of the memory allocation. (Out of Memory).
• Arrays of Pointers
  • Typical example array of strings.
  • Command line arguments
• Characters - ctype library

Administrative
