Correct Answer: A structure which contains a char pointer which points to the first character of a file.
Explanation:
The fp is a structure which contains a char pointer which points to the first character of a file.
Correct Answer: standard error streams
Explanation:
The standard error(stderr) stream is the default destination for error messages and other diagnostic warnings. Like stdout, it is usually also directed to the output device of the standard console (generally, the screen).
Correct Answer: rem = fmod(5.5, 1.3)
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.
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 5.5 by 1.3 is %lf\n", fmod (5.5, 1.3) );
return 0;
}
Output:
fmod of 5.5 by 1.3 is 0.300000
