right filling string till length = 5

Posted on 2000-03-28

Here is my code for starters:
    /*5 spaces */
    strcpy(wc,"     ");
    strcat(com_buffer, wc);
   if(strlen(wc) != 5);
       /* fill to the right with spaces till length = 5 */
       strcat(com_buffer, wc);
   else strcat(com_buffer, wc);

Where the comment is to fill to the right is where I need to insert the code that will take the length of wc if less than 5 anf fill it to the right with spaces.  So if user inputs "a" wc becomes "a    " and so on.

A simple rewrite for the whole thing could be:

while(strlen(wc)<5)strcat(wc," ");

I'm assuming that since your first action in your code is to do a strlen on wc, wc does in fact contain a reasonable string, although it might be a null string.
Given that you can skip the first case since you can append stuff to null strings with strcat.
