The modulus operator cannot be used with a long double.
True
False
Answer: Option
Explanation:

fmod(x,y) - Calculates x modulo y, the remainder of x/y.
This function is the same as the modulus operator. But fmod() performs floating point or long double divisions.

If I am right, fmod(x,y) is a function. And the question is "The modulus operator cannot be used with a long double". Then the answer should be (B). Because we can not use modulus operator with float or double. For this, we use the function in math.h header file which is fmod().

I think the answer is B.

It is not possible to perform modulo operator with float and double.

Is this means that modulus operator works ONLY on integers?

example for fmod:
#include<stdio.h>
#include<math.h>
int main()
{
float x=10.10,y=2.0, z;
z=fmod(x,y);
printf("%f", z);

return 0;
}
