You could write an rtrim() function that will remove all whitespace (i.e.
spaces, tabs, newline chars, etc) from the right side of your string.

Here's an example of the function:

#include <ctype.h>

char *rtrim(char *string)
 {
  int i = strlen(string) - 1;

  if (i < 0) return(string);

  while (isspace(string[i]) && i >= 0)
   {
    string[i] = '\0';
    i--;
   }

  return(string);
 }
