C++ .crbegin()

In C++, the .crbegin() method returns a const_reverse_iterator referring to the last element of the given array, i.e., the first element in reverse order. Because the iterator is constant, it cannot be used to modify the underlying elements.

Syntax

container.crbegin()

Parameters:

.crbegin() takes no parameters.

Return value:

Returns a const_reverse_iterator referring to the last element of the given array.

Example

This example prints the elements of an array in reverse order using constant reverse iterators (.crbegin() and .crend()):

#include <array>
#include <iostream>

int main() {
  std::array<int, 5> nums = {10, 20, 30, 40, 50};

  // Print the array in reverse using .crbegin() and .crend()
  for (auto it = nums.crbegin(); it != nums.crend(); ++it) {
    std::cout << *it << ' ';
  }
  std::cout << '\n';
}
