How do I find items in std::vector?

Write std::find in <algorithm>

std::find(vector.begin(), vector.end(), item) != vector.end()

You can use it with this Returns true if the item exists, and false if it does not exist.

I'll attach a simple example

#include <algorithm>

if ( std::find(vector.begin(), vector.end(), item) != vector.end() )
   do_this();
else
   do that();
