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(         


        

Answer 1

template  bool IsInVector(const T & what, const std::vector & vec)
{
    return std::find(vec.begin(),vec.end(),what)!=vec.end();
}
