std::vector

[Nirit]

trying to print a vector in a reverse order. receiving casting error on the last loop. don't understand why.

#include<iostream>
#include <vector>
int main()
{
	std::vector<char> vec(26);///init vector of size 26 to contain a-z letters
	
	// fill vector values from a to z
	std::cout << "print in order" << std::endl;
	for (auto& elem : vec)
	{
		//elem is the value of the organ in the vector

		// if the current index is needed:
		auto i = &elem - &vec[0];
		elem = 'a' +i;

		std::cout << elem << " ";
	}

	//print in reverse order
	std::cout << "print in reverse order" << std::endl;
	for (std::vector<int>::reverse_iterator rit=vec.rbegin();rit!=vec.rend();rit++)
		std::cout << *rit << " ";


	return 0;
}

// for (std::vector<int>::reverse_iterator rit=vec.rbegin();rit!=vec.rend();rit++)
for (std::vector<char>::reverse_iterator rit=vec.rbegin();rit!=vec.rend();rit++)

Use auto to avoid silly errors like this:
for( auto rit = vec.rbegin() ; rit != vec.rend() ; ++rit )
