  1. Re: strcmp on Linked List data and string constants?

    sorry, it seems to be working just fine. strcmp() returns a 0 when both character arrays are the same. :)
  2. [RESOLVED] strcmp on Linked List data and string constants?

    Was wondering why strcmp() doesn't return true when comparing a string constant with a string that was acquired via a linked list. By the way, the data in the linked list was taken from a text file....

    Re: Linked Lists and Pointers

    Thanks, for that very detailed explanation 2kaud! Looks like I have a huge lot to learn about linked lists (among other things). I'll try to digest this for a while :)

    Re: Linked Lists and Pointers

    Yup, edited them. Thanks. :)

    I have a question, this will possibly clear up all of my confusion in the crtNode(), or make it even more confusing for me (hopefully not). Taking your code as an...

    Questions/Clarifications:


    while(curNode)

    This is the same as while(curNode != NULL) right?

    I tried using the Debug and Watch in Turbo C (used start and val for the watched values) but it said undefined symbol on both instances. Then I tried using Watch on CodeBlocks but it doesn't look...

  17. Re: Is there such a thing as code withdrawal in a compiler?

    I know, that's why:



    do {
    printf("Please enter your name (50 characters max): ");
    fflush(stdin);
    fgets(nme, sizeof(nme), stdin);
    printf("\nName: %s", nme);
  18. Re: Is there such a thing as code withdrawal in a compiler?

    @SeventhStar: Before the fflush(), if the input is "Rie Ishida", it only got the "Rie" part and saves the "Ishida" part to the following scanf().

    Cool! Thanks a lot! That fixed my problem with the...

    By code withdrawal, I mean, like certain functions not working at all (or being shunned/passed by the compiler). In the code below, I've been getting to make the fgets() work in Turbo C (running in...

    Re: Assigning a value to struct variables?

    I was told that using !feof() is a bad thing to do, so I guess I'll stick to my while statement? So the output is still the same. I really don't know what I'm doing wrong here, as to why the extra...

    My output:

    Rie Ishida
