    An empty string is represented by pointer to null character.

    clear it to what. Spaces, or null characters?
    one would be
    Code:
    for(x=0;x<strlen(string);x++){
         array[x]='\0';
    }
    or if it is a pointer.
    Code:
    pointerarray=NULL;

    I think he means clear as in destroy, erase, incinerate or make-so-it's-lengt-wold-be-0.

    EDIT: linuxdude, why wold anyone want to fill entire string with null characters?

    That would be my choice, unless of course the programmer is trying to destroy the data.
