with a simple bluf I think

# include <iostream>
using namespace std;

int main()
{
    float nbr=0;
    cout << "Enter your number -> ";cin >> nbr;

    int nbr2 = (int)nbr;
    cout << nbr << " ->bigger is " << nbr2+1 << " and smaller is " << nbr2 << endl;

    return 0;
}

hope it helps

In c++ use the functions floor() and ceil().
