#include <stdio.h>
int main()
{
    int num, arr1[100];
    printf("Enter number of terms to be stored in array: ");
    scanf("%d", &num);
    int i, j;
    printf("Enter %d elements\n", num);
    for (i = 1; i <= num; i++)
    {
        printf("Element %d - ", i);
        scanf("%d", &arr1[i]);
    }
    int arr2[100];
    for (i = 1; i <= num; i++)
    {
        for (j = i; j <= num; j++)
        {
            arr2[j] = arr1[i];
        }
    }
    printf("Printing the copied elements\n");
    for (j = 1; j <= num; j++)
    {
        printf("%d ", arr2[j]);
