﻿ C++ : New array swapping first, last elements of an array # C++ Exercises: Create a new array swapping the first and last elements of a given array of integers and length will be least 1

## C++ Basic Algorithm: Exercise-95 with Solution

Write a C++ program to create a new array swapping the first and last elements of a given array of integers and length will be least 1.

Sample Solution:

C++ Code :

``````#include <iostream>
using namespace std;

static int *test(int numbers[], int arr_length)
{
int first = numbers;
numbers = numbers[arr_length - 1];
numbers[arr_length - 1] = first;

return numbers;
}

int main () {
int *p, i;
int nums1[] = { 1, 5, 7, 9, 11, 13 };
cout << "Original array:" << endl;
int arr_length = sizeof(nums1) / sizeof(nums1);
for ( i = 0; i < arr_length; i++ ) {
cout << nums1[i] << " ";
}
p =  test(nums1, arr_length);
cout << "\nNew array (after swapping the first and last elements of the said array): " << endl;
for ( i = 0; i < arr_length; i++ ) {
cout << *(p + i) << " ";
}
return 0;
}
``````

Sample Output:

```Original array:
1 5 7 9 11 13
New array (after swapping the first and last elements of the said array):
13 5 7 9 11 1
```
