C++ Exercises: Create an array taking two middle elements from a given array of integers of length even
C++ Basic Algorithm: Exercise-94 with Solution
Write a C++ program to create an array taking two middle elements from a given array of integers of length even.
Sample Solution:
C++ Code :
#include <iostream>
using namespace std;
static int *test(int numbers[], int arr_length)
{
static int r_array[] = { numbers[arr_length / 2 - 1], numbers[arr_length / 2] };
return r_array;
}
int main () {
int *p, i;
int nums1[] = { 1, 5, 7, 9, 11, 13 };
cout << "Original array:" << endl;
int arr_length = sizeof(nums1) / sizeof(nums1[0]);
for ( i = 0; i < arr_length; i++ ) {
cout << nums1[i] << " ";
}
p = test(nums1, arr_length);
cout << "\nNew array: " << endl;
arr_length = sizeof(p) / sizeof(p[0]);
for ( i = 0; i < arr_length; i++ ) {
cout << *(p + i) << " ";
}
return 0;
}
Sample Output:
Original array: 1 5 7 9 11 13 New array: 7 9

Previous: Write a C++ program to check a given array of integers, length 3 and create a new array. If there is a 5 in the given array immediately followed by a 7 then set 7 to 1.
Next: 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.
