whatz wrong in std::vector< myclass >::iterator

[John]

I have a function declaration that gives an error while compiling.
Can anyone help me figure this one out?

inline void create(const std::vector< myclass >& plist,
std::vector< myclass >::iterator
left,
std::vector< myclass >::iterator
right);

x.hpp:153: error: `class std::vector<myclass, D>, std::alloca
tor<myclass> >::iterator' is not a type
x.hpp:154: error: `class std::vector<myclass, std::alloca
tor<myclass> >::iterator' is not a type
x.hpp:154: error: ISO C++ forbids declaration of `left' with no type
x.hpp:154: error: ISO C++ forbids declaration of `right' with no type

I am trying to port some old code to a new machine. Also what happened
to algobase.h?

Thanks,

No such thing. You might want <algorithm>

yes it does include <vector>

I corrected the problem by using

typedef typename std::vector<myclass>::iterator vit

and then it works...

Hi

Try using the typename keyword.

I.E.
template <typename MyClass>
void create(std::vector<MyClass>& p_list, typename
std::vector<MyClass>::iterator p_left, typename
std::vector<MyClass>::iterator p_right);

std::vector<MyClass>::iterator can be either a type or a member. The
typename keyword makes it less ambiguous, by telling the compiler that
std::vector<MyClass>::iterator is a type.

As for algobase.h, try #include <algorithm>

The OP didn't come up with a template so there's no need to use a typedef
