There is a common Find() template to achieve what you want. It is applied to a number of containers, not only Vector.
But I doubt if slow sequential search is a good idea at all. If you want Vector and you want to have quick search, make it sorted. Add items by using FindUpperBound()-like calls, then you may search with FindBinary() which costs O(log(n)), not O(n) as for sequential search.
