Question

So I was looking for a way to search a string in a list of strings. I have coded the following

bool contains(const std::list<std::string>& data, const std::string& str)
{
        std::list<std::string>::iterator i;
        for(i=data.begin(); i!=data.end(); ++i)
        {   
                if (str == *i) 
                        return true;
        }   

        return false;

}

This is just a very basic code. I m aware of the find method but it takes in the start and end . Ideal solution would be taking entire container. There are some boost methods for the same , however I m not sure how to use them. can you give some example for boost find for generic searching of element.

Answer 1

Use Boost.Range:

#include <boost/range/algorithm/find.hpp>

auto i = boost::find(container, value);
if (i != boost::end(container))
  doSomething(*i);
