how to reverse an array in c++ without loop code example

Example 1: for loop reverse C++

// Using iterators
for (auto it = s.crbegin() ; it != s.crend(); ++it) {
  std::cout << *it;
}

// Naive
for (int i = s.size() - 1; i >= 0; i--) {
  std::cout << s[i];
}

Example 2: c++ reverse array

int arr[5] = {1, 2, 3, 4, 5}; //Initialize array

for(int i = 0; i < size(arr); i++) {
	//Create temporary variable to hold current value in array
	int temp = arr[i];
	//Set the current value in the array to the mirrored value in array
	arr[i] = arr[size(arr) - 1 - i];
	//Set mirrored value in array to temp, swapping the two numbers
	arr[size(arr) - 1 - i] = temp;
}
