It's also fairly sad and inelegant use of recursion, with the extra cursor being passed around. The way I learned recursion, you start by seeing an array as either empty, or having a head element, and then: // vaguely Haskell-like pseudo-code ismember(value, []) -> false ismember(value, head:tail) -> value==head || ismember(value, tail) My point is, I'm not sure the students will appreciate recursion properly based on that code, if that's the intention. (Perhaps not based on any C++ code.) /Jorgen -- // Jorgen Grahn <grahn@ Oo o. . . \X/ snipabacken.se> O o . |
