0 votes
#include <iostream>
#include <vector>

using std::vector;
using std::cout;
using std::endl;

int main()
{
	vector<int> vec = { 1, 3, 8, 23, 88, 12, 99, 7 };

	vector<int>::const_iterator pos;

	pos = find(vec.cbegin(), vec.cend(), 23);

	cout << "pos:  " << *pos << endl;

	// convert iterator to reverse iterator 
	vector<int>::const_reverse_iterator rpos(pos);

	cout << "rpos: " << *rpos << endl;
}


/*
run:

pos:  23
rpos: 8

*/
