void main()
{
    int number, sum = 0, rem = 0, cube = 0, temp;

    if (sum == temp)
        printf ("The given no is armstrong no");
    else
        printf ("The given no is not a armstrong no");
}

Output :

enter a number : 370
The given no is armstrong no

enter a number : 1500
The given no is not a armstrong no
