Write a C program to create an array taking two middle elements from a given array of integers of length even.

C Code:

#include <stdio.h>
#include <stdlib.h>

// Function prototype for 'print_array'
void print_array(int parray[], int size);

int main(void){
    // Declaration and initialization of variables
    int new_arr_size = 2; // Size of the new array
    int arr_size; // Size of the original array

    // Declaration and initialization of the original array 'nums1'
    int nums1[] = { 1, 5, 7, 9, 11, 13};

    // Calculating the size of the original array
    arr_size = sizeof(nums1)/sizeof(nums1[0]);

    // Printing elements in the original array
    printf("Elements in original array are: ");  
    print_array(nums1, arr_size);  

    // Creating a new array with middle two elements of the original array
    int result[] = { nums1[arr_size / 2 - 1], nums1[arr_size / 2] };

    // Printing elements in the new array
    printf("New array: ");  
    print_array(result, new_arr_size);        
} 

// Definition of the 'print_array' function
void print_array(int parray[], int size)
{
   int i;      
   for( i=0; i<size-1; i++)  
    {  
        // Printing each element with a comma and a space
        printf("%d, ", parray[i]);  
    } 
    // Printing the last element without a comma and space
    printf("%d ", parray[i]);  
    // Printing a new line to separate the elements
    printf("\n");   
}

Sample Output:

Elements in original array are: 1, 5, 7, 9, 11, 13 
New array: 7, 9

Previous: Write a C program to compute the sum of the two given arrays of integers, length 3 and find the array which has the largest sum.
Next: Write a C program to create a new array from two give array of integers , each length 3.
