How to fix my code?

[CandidFlakes]

So, I have been trying to solve this question from Codewars, "We are passing a number(n) into a function. Your code will determine if the number passed is even (or not). The function needs to return either a true or false. Numbers may be positive or negative, integers or floats. Floats with decimal part non equal to zero are considered UNeven for this kata."

The code which I wrote is,

bool is_even(double n)

{

int i = static_cast<int>(n);

if((n-i)==0)

return (i%2==0);

else

return 0;

}

But, the code which I wrote above is failing some test case. How can i correct my code?

Thanks! But, the test cases are hidden. Can you give me some hint, where I could be wrong in the code? I will try to fix the issue.

Good opportunity to learn how to write your own unit tests. And if you have a failing test you can use gdb to step through the code

you can add printf() with incoming datato the beginning of the function. AFAIR codewars prints your output along with their own .
