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

fmod is not working in GCC compiler. How can I use this in GCC compiler?
Please suggest me to get the output of this.

Yes, because the given values are in floating type so we also want the ans in floating type therefore we use fmod().

#include<stdio.h>
#include<conio.h>
void main()
{
float a,b,c;
c=a%b;
printf("%f",c);
}
#include<conio.h>
void main()
{
float a,b,c;
c=a%b;
printf("%f",c);
}

Yes. For int only we can use mod for float we should use fmod the answer should be c only for this problem.

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

Ya. Its nice ans we use % and mod () , fun for int, type but not for float hence fmode is right answer.

Step by step process:
a = XXX * 10
a = ABC - XYZ * 10
a = 20 - 10* 10
a = 20 - 100
a = -80

a = XXX * 10
a = ABC - XYZ * 10
a = 20 - 10* 10
a = 20 - 100
a = -80

C is the correct answer as % operator don't work on floating point numbers so A is incorrect.

Please clarify my doubt.
What is the meaning of "External declaration and Where is use" ?

Option A is also correct becuase;
int rem=3.14/2.1;
printf("%d",rem);
return();
int rem=3.14/2.1;
printf("%d",rem);
return();
