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

#include <stdio.h>
#include <math.h>
int main ()
{
printf ("fmod of 3.14/2.1 is %d\n", fmod(3,2) );
return 0;
}
I am getting output as 0. Anyone can explain it why?
#include <math.h>
int main ()
{
printf ("fmod of 3.14/2.1 is %d\n", fmod(3,2) );
return 0;
}

What is wrong in this code why it will give segmentation fault?
#include <stdio.h>
void main()
{
register int x = 0;
if (x < 2)
{
x++;
main();
}
}
#include <stdio.h>
void main()
{
register int x = 0;
if (x < 2)
{
x++;
main();
}
}

What different between fmod & modf?

@Ayapan.
You have declared the fun as fmod(3, 2).
When 3 gets divided by 2 it gives 1.5 with remainder 0.

@Vani.
printf inside the printf....firstly there is a abc and also a slace is a character literal so there it work as a character...and 1 char is 1 byte so 4 character print 4...on place of printf("%d",4 );
Due to %d it'll print 4.

Why we can use the fmod? instead of that what word is apt for the execution.

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

The output of following program is:
#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?
