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(

You can use count too. It will return the number of items present in a vector.

int t=count(vec.begin(),vec.end(),item);
