void read_array(int a[MAX], int n)
{
    int i;
    for(i=0;i<n;i++)
    {
        printf("Element %d\t:",i+1);
        scanf("%d",&a[i]);
    }
}

void main()
{
    int arr[MAX];
    int i, n, num, flag;

    printf("Enter the number of elements in the array\t:");
    scanf("%d",&n);

    printf("Enter the elements of the array\n");
    read_array(arr, n);

    printf("Enter the element to be searched\t:");
    scanf("%d", &num);

    flag = 0;
    for(i=0;i<n;i++)
    {
        if(arr[i]==num)
        {
            flag = 1;
            printf("\nElement found at position %d",i+1);
        }
    }

    if(flag == 0)
