define variable

Question

Is there anyway to define variables at only one line that doesnt alter its value at all other line for exp i want to find quotient of a diving b so i have to double a, b; but at other line to find the remainder of a diving b it must be integer so how to define a and b as integer at only that line

Answer 1

void doAllThat(double a, double b)
{
cout << a / b << endl;
cout << int(a) % int(b) << endl;
}
Forgive me, if that's not what you're asking about, but I've had a hard time understanding your question.
Also it's better to use round(), floor() or ceil() instead of int(). Like this: cout << floor(a) % floor(b) << endl;
