How to find out if an item is present in a std::vector?

Question

All I want to do is to check whether an element exists in the vector or not, so I can deal with each case.

if ( item_present )
   do_this();
else
   do_that(

With boost you can use any_of_equal:

#include 

bool item_present = boost::algorithm::any_of_equal(vector, element);
