C Exercises: Create a new array of length 3 from a given array containing the elements from the middle of the array
C-programming basic algorithm: Exercise-49 with Solution
Write a C program to create a new array of length 3 from a given array (length atleast 3) containing the elements from the middle of the array.
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[0]);
printf("Elements in original array1 are: ");
print_array(nums1, arr_size1);
int result[] = { nums1[arr_size1 / 2 - 1], nums1[arr_size1 / 2], nums1[arr_size1 / 2 + 1]} ;
printf("New array: ");
print_array(result, 3);
}
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: 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).

C Programming: Tips of the Day
Static variable inside of a function in C
The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().
The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.
The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
