(C++) std::find_if

STL algorithm for searching an elements in a container, satisfying a certain predicate.

#include <cassert>

#include <iterator>

#include <vector>

int main()

{

typedef std::vector<int>::const_iterator Iterator;

std::vector<int> v;

v.push_back(-2);

v.push_back(-1);

v.push_back( 0);

v.push_back( 1);

v.push_back( 2);

//Find the first element in v that has an integer value bigger then zero

const Iterator result

= std::find_if(v.begin(), v.end(),

std::bind2nd(std::greater<int>(), 0));

assert(result == v.end() && "A result is found");

assert(*result > 0 && "The result found is valid");

}
