## C-programming basic algorithm: Exercise-48 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.

C Code:

``````#include <stdio.h>
#include <stdlib.h>
int main(void){
int arr_size1;
int nums1[] = {1, 5, 7, 9, 11, 13};
arr_size1 = sizeof(nums1)/sizeof(nums1);
printf("Elements in original array1 are: ");
print_array(nums1, arr_size1);
int result[arr_size1];
for (int i = 0; i < arr_size1; i++) {
result[i] = nums1[i];
}
int first = nums1;
result = nums1[arr_size1 - 1];
result[arr_size1 - 1] = first;

printf("New array, after swapping first and last elements: ");
print_array(result, arr_size1);
}
print_array(int parray[], int size)
{
int i;
for( i=0; i<size-1; i++)
{
printf("%d, ", parray[i]);
}
printf("%d ", parray[i]);
printf("\n");
}
``````

Sample Output:

```Elements in original array1 are: 1, 5, 7, 9, 11, 13
New array, after swapping first and last elements: 13, 5, 7, 9, 11, 1
```
