Use ceil instead of round because you need nearest whole positive number.

cout<<int(ceil(c));

Answer 2

int d = round(c);
cout<<d;

Answer 3

round (4.4) = 4
ceil(4.4) = 5

round (4.6) = 5
ceil(4.6) = 5

remember in C++ gives 4 or 5 as int instead of 4.0 or 5.0

in Java returns 4.0 or 5.0 as double value
