How do you get the remainder in C++?

Question

I wrote the problem as: quotient = num - 19*int(num/19)
I only get the quotient though but I need to get the remainder as well. I know you need to put this symbol % in the problem but I don't know where it'll fit without giving you errors. Please help.

Also the tutorials online were of little or no help when it came to getting a remainder.

Answer 1

% will give you the remainder.



remainder = num % 19;

Answer 2

In your equation, it looks like you're multiplying by 19, then dividing by 19, which could be canceled out.



Anyways, the remainder you're looking for can be found using the modulus (%) operator. You would put that where you need it instead of the division operator to get the remainder.

Answer 3

Try the modf() function: http://www.cplusplus.com/reference/clibrary/cmath/modf/
