Is there a C++ Function that determines if a number is even or odd? If, so what is it please.?

Answer 1

you can use a simple function of your own:

void tell(int x)
{
if(x%2==0)
cout<<"even";
else
cout<<"odd";
}

Answer 2

The % is a modulus operator. it divides by whatever number you put behind it and returns the remainder. if the remainder is = to 0 then it is divisible. Hence %2==0 then, else

Answer 3

Even simpler - just use the & operator. You can make a macro:

#define ODD(XX) ((XX) & 1)

Answer 4

another way is:

int number;

if ((number & 0x1) == 0x0)
//even
else
//odd

Answer 5

yes. see above
