[C++] cbegin, crbegin, cend, crend

Concept

r : reverse

cbegin : 0 ~ cend : last

crbegin : last ~ cend : first

Code

// vector::crbegin/crend
#include <iostream>
#include <vector>
#include <string>

using namespace std;

int main ()
{
  vector<int> myvector = {1,2,3,4,5};
  vector<int>::iterator low,up;

  for (auto rit = myvector.crbegin(); rit != myvector.crend(); ++rit)
  std::cout << ' ' << *rit;
  std::cout << '\n';
  
  
   for (auto rit = myvector.cbegin(); rit != myvector.cend(); ++rit)
   std::cout << ' ' << *rit;

  return 0;
}
