reverse of an array c++ code example

Example 1: reverse an array in c++

#include <iostream>
using namespace std;
int main()
{		// While loop
	const int SIZE = 9;
	int arr [SIZE];
	cout << "Enter numbers: \n";
	for (int i = 0; i < SIZE; i++)
		cin >> arr[i];
	for (int i = 0; i < SIZE; i++)
		cout << arr[i] << "\t";
	cout << endl;
	cout << "Reversed Array:\n";
	int temp, start = 0, end = SIZE-1;
	while (start < end)
	{
		temp = arr[start];
		arr[start] = arr[end];
		arr[end] = temp;
		start++;
		end--;
	}
	for (int i = 0; i < SIZE; i++)
		cout << arr[i] << "\t";
	cout << endl;	
  	return 0;
}

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;
}
