    Is this the correct way...

    to get a user array of string input?

    Code:
    printf("Title: ");
    scanf("%[^\n]", title);
    while(fgetc(stdin)!='\n');
    if no, can you advise what are the ways to get an array of string, eg. "C rulez big time" coz I've been getting funny result with the method above.

    Nope, using scanf for string input is unsafe, when you manage to do it safely it's just an ugly kludge. Try this instead:
    Code:
    printf("Title: ");
    fflush(stdout);
    if (fgets(title, sizeof title, stdin) != NULL) {
            /* Use title */
    } else {
            /* fgets failed */
    }
