Alternate

Description:

There is a machine in a lab which is working not properly. It displays the alternative elements in a set of input. The lab instructor asked the students to write a C Program for this scenario. i.e. to Print the Alternate Elements in an Array Test Case 1 Input (stdin) 5 21 8 41 13 15 Expected Output 21 41 15 Test Case 2 Input (stdin) 9 2 8 4 1 3 6 8 11 38 Expected Output 2 4 3 8 38

Program :

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

int main()
{
    int i,n;
    
    scanf("%d",&n);
    int a[n];
    for(i=0;i<n;i++)
    {
        
        scanf("%d",&a[i]);
    }
    printf("\n");
    for(i=0;i<n;i++)
        //printf("%d \t",a[i]);

    printf("\n\t");
    for(i=0;i<n;i=i+2)
       printf("%d \t",a[i]);

    return 0;
}
