c++ program to reverse an array

#include<iostream>
using namespace std;
int main()
{
   int a[]={1,2,3,4,5};  // Using Pointer and Array Relationship
    for (int i = 4; i>=0; i--)
    cout<<*(a+i);
   return 0;
}

reverse function in cpp array

// C++ program to reverse Array
// using reverse() in STL
 
#include <algorithm>
#include <iostream>
using namespace std;
 
int main()
{
    // Get the array
    int arr[] = { 1, 45, 54, 71, 76, 12 };
 
    // Compute the sizes
    int n = sizeof(arr) / sizeof(arr[0]);
 
    // Print the array
    cout << "Array: ";
    for (int i = 0; i < n; i++)
        cout << arr[i] << " ";
 
    // Reverse the array
    reverse(arr, arr + n);
 
    // Print the reversed array
    cout << "
Reversed Array: ";
    for (int i = 0; i < n; i++)
        cout << arr[i] << " ";
    return 0;
}

reverse an array in c++ stl

//Reverse an array using C++ STL
#include <algorithm>  //Header file for reverse method

 int arr[] = { 1, 2, 3, 4, 5 };
 int n = sizeof(arr) / sizeof(arr[0]);  //Size of array
 reverse(arr, arr + n);
 //Now array looks like = { 5, 4, 3, 2, 1 }
 //The time complexity is O(n)
