So you have a node structure, and an array of these structures, and you want to set a pointer variable to point at the ith node in the array.

You can do this in exactly the same way you would if it was an array of longs:
Expand|Select|Wrap|Line Numbers
  1. int i;
  2. long *p, array[100];
  3. ...
  4. p = &array[i];
