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>
main()
{
printf("%d",printf("ABC\"));
}
Can anyone please explain how it gives o/p as ABC4 ?
main()
{
printf("%d",printf("ABC\"));
}
Can anyone please explain how it gives o/p as ABC4 ?

@Vani :
In the inner printf statement, there are 4 characters.
The output of a printf stmt is a integer. that number is equal to the number of Characters that the printf statement printed.
For example:
printf("%d",printf("ABC"));
o/p= ABC4
-----------
printf("%d",printf("A"));
o/p= A1
-----------
printf("%d",printf("AB"));
o/p= AB2
-----------
printf("%d",printf("ABC10"));
o/p= ABC105
(here 10 is taken as two different characters.)

% operator is not use for floating operations it is only used for integers.

Why did ansi form fmod() operator when % already was. It could be used for both the purpose. Integers as well as float?
