C++ Exercises: Create a new array length 3 from a given array the elements from the middle of the array

C++ Basic Algorithm: Exercise-96 with Solution

Write a C++ program to create a new array length 3 from a given array (length atleast 3) using the elements from the middle of the array.

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;

 static int* test(int numbers[], int arr_length)
          {          	     	         	
          	static int result[] { numbers[arr_length / 2 - 1], numbers[arr_length / 2], numbers[arr_length / 2 + 1] };
          	return result;
          } 
            
int main() 
 {  
  int *result, i;
  int nums[] = {1, 5, 7, 9, 11, 13};  
  int arr_length = sizeof(nums) / sizeof(nums[0]);
  
  cout << "Original array:" << endl; 
  
  for ( i = 0; i < arr_length; i++ )  
    cout << nums[i] << " "; 
	      
  result = test(nums, arr_length); 
  cout << "\nNew array:" << endl;   
   arr_length = sizeof(result) / sizeof(result[0]);   
   for ( i = 0; i <= arr_length; i++ ) {
      cout << *(result + i) << " ";
   } 
   
  return 0;    
}

Sample Output:

Original array:
1 5 7 9 11 13 
New array:
7 9 11

Previous: 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.
Next: Write a C++ program to find the largest value from first, last, and middle elements of a given array of integers of odd length (atleast 1).
