First of all strcpy() copies a string, not a char, what you do for your readin routine I have no idear of, since all it seems to be is a while loop that does absolutely nothing.

Something like this will do the trick:

#include <stdio.h>
#include <string.h>
#define LINE_SIZE 20

int main()
{
  char correct_word[LINE_SIZE +1], reverse_word[LINE_SIZE+1];
  int i, j;
  printf("Please enter word to be reversed: ");
  fflush(stdout);
  if(!fgets(correct_word, LINE_SIZE, stdin))
    {
      printf("Error reading word from stdin\n");
      return -1;
    }
  /* correct for teh '\n' and '\0' from the read string */
  j = strlen(correct_word) -2;
  for(i = 0; j >= 0; )
    reverse_word[i++] = correct_word[j--];
  /* make sure reversed word isn't ending in garbadge */
  reverse_word[i] = '\0';
  printf("Read word was: %s", correct_word);
  printf("Reversed word: %s\n", reverse_word);
  return 0;
}
