Which of the following statements should be used to obtain a remainder after dividing 3.14 by 2.1 ?
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 divisions.
Example:
#include <stdio.h>
#include <math.h>
int main ()
{
printf ("fmod of 3.14/2.1 is %lf\n", fmod (3.14,2.1) );
return 0;
}
Output:
fmod of 3.14/2.1 is 1.040000

It means % operator is use when we are doing integer division to get the remainder?

@Dinesh Kumar.
#include<stdio.h>
int main()
{
int a=1;
printf("%d %d %d",a,a++,++a);
return 0;
}
Output : 3 2 3.
But logically 3 2 2.
Can any explain how 3 2 3 comes?
Your logic is true,function data passing is from right to left. So first ++a execute then a++,then a.
But the current value of a will be substitute in pre-increment operator always.
So the output will be 3 2 3.
#include<stdio.h>
int main()
{
int a=1;
printf("%d %d %d",a,a++,++a);
return 0;
}
Output : 3 2 3.

#include <stdio.h>
#include <math.h>
int main ()
{
float 3.13.2.1;
float R;
R=fmod(3.14,2.1);
printf ("The remainder is:",R);
scanf("%f",R);
return 0;
}
It will show error, because you write
float 3.13.2.
#include <math.h>
int main ()

float 3.13.2.1;

No @Keerthi.
The floating point remainder cannot be obtained by modulo operator.
The floating point remainder cannot be obtained by modulo operator.

What is the work of the fmod?

The answer could be option A (i.e) rem = 3.14 % 2.1 ?

% operator represents Reminder in C Language
But it is not possible for floating point operations.So,the Answer would be option (d).
(d)Remainder cannot be obtain in floating point division.
