#include <stdio.h>

int main() {
int arr[100], n, i;

// Accept number of elements
printf("Enter the number of elements: ");
scanf("%d", &n);

// Accept array elements
printf("Enter %d elements:\n", n);
for (i = 0; i < n; i++) {
scanf("%d", &arr[i]);
}

// Print alternate elements (0th, 2nd, 4th, ...)
printf("Alternate elements in the array:\n");
for (i = 0; i < n; i += 2) {
printf("%d ", arr[i]);
}
printf("\n");

return 0;
