How to search for an element in an stl list?

Question

Is there a find() function for list as there was in vector?

Is there a way to do that in list?

Answer 1

Besides using std::find (from algorithm), you can also use std::find_if (which is, IMO, better than std::find), or other find algorithm from this list

#include

#include 

int main()
{
    std::list myList{ 5, 19, 34, 3, 33 };
    

    auto it = std::find_if( std::begin( myList ),
                            std::end( myList ),
                            [&]( const int v ){ return 0 == ( v % 17 ); } );
        
    if ( myList.end() == it )
    {
        std::cout << "item not found" << std::endl;
    }
    else
    {
        const int pos = std::distance( myList.begin(), it ) + 1;
        std::cout << "item divisible by 17 found at position " << pos << std::endl;
    }
}
