c - Parsing user input using time_t -


I think, if the user enters in t = 2.5 , then i will get 2 and 0.5 Separate 2 different variables but I am unable to do this.

Here the code is: 

  $ export LT_LEAK_START = 1.5 $ echo $ LT_LEAK_START 1.5 #include & lt; Stdio.h & gt; # Include & lt; Stdlib.h & gt; # Include & lt; Time.h> Int main () {Double D; Time_t; Long NSE; D = Stroke (getenv ("LT_LEAK_START"), NULL); T = (Time_T) d; Nsec = D (double) ((time_t) d); Remove partial part as // time_t is not always complete Printf ("d =% lf \ n", d); Printf ("t =% u, nsec =% f \ n", d, nsec); }   
 Output is:  
  # ./a.out d = 1.500000 t = 0, nsec = 0.000000   < / Div> 
 
 
 Your output is broken. You are actually writing the value of  d  in the following code twice:  
  nsec = d- (double) ((time_t) d); Remove partial part as // time_t is not always complete Printf ("d =% lf \ n", d); Printf ("t =% u, nsec =% f \ n", d, nsec);   
 If you have written it:  
  nsec = d- (double) ((time_t) d); Remove partial part as // time_t is not always complete Printf ("d =% lf \ n", d); Printf ("t =% u, nsec =% f \ n", t, nsec);   
 Then you will have output:  
  d = 1.500000 t = 1, nsec = 0.000000   
 now Obviously you have a round error. In this situation, you remove all decimal places by specifying 0.5 to  nsec , a  long . Instead  nsec  a  float .
