Thread: C++ divisible by 10

#include <iostream>
#include <math.h>
using namespace std;
main ()
{
     float num;
     cout<<"Enter #: ";
     cin>>num;
     
     float ans=num/10;
     float a[10];
     
     for(int i=0; i<=10; i++)
     {
            a[i]=ceil(ans*i);
             
     }
     for(int x=10; x>=0; x--)
     {
             cout<<a[x]<<endl;
