  I'm writing a program that creates combinations. It (should) work this way:
there's a string containing possible characters, and I need all the possible
combinations of X characters. What I need is an array of X pointers, so I could do
this way:
/ = pointer[0]        \ =pointer[1]

at beggining:
/
\   
A   B   C    D    E
then and output would be created in the form: *pointer[1], *pointer[0]. Next
combination: I move pointer[0] one character, this way:
      /
\   
A   B   C    D    E
this would output now 'ab', and so on. When pointer[0] reaches the end and is
updated, it should point again to the beggining, and pointer[1] should move one
character:
/
      \   
A   B   C    D    E
and so on... My questions are: how do I create this array of pointers? what's the
best method to do this 'end' movement?
