Which of the following is the correct output for the program given below?

#include <stdio.h>
int main ( )
{
      float n = 2.39;
      printf("%f %f\n", ceil (n), floor (n)) ;
      return 0 ;
}

1. 3.000000 2.000000
2. 2.500000 2.500000
3. 2.550000 3.000000
4. 2.000000 3.000000

Correct Option: A

ceil(n) round up the given value. It finds the smallest integer not < n.
floor(n) round down the given value. It finds the smallest integer not > n.

So output is
3.000000 2.000000
