    Need help to fix code

    Hello guys, I made program using with c. And i found compiling is not successful because small error. Please see full coding work below and error is highlighted in colour. Please help me to fix this code as i have to give this Assignment today. Do something. Thanking you
    Code:

    Ok, I've done something - I just stood up and jumped on one leg across the room. That will give you good luck.

    However, if you want more constructive help, I could perhaps help you figure out what the error is if you tell us what the actual error is...

    You didn't try to declare a variable of type num, did you?

    The problem with your code is that there's a HUGE RED LINE in the middle of it. Your compile doesn't understand HUGE RED TEXT. Try using smaller letters, and maybe a different color.

    I told you code in red colour was highlighted when i compiled it. I used Dev Shed software. The error said:

    1) variable or field `replaceNode' declared void
    2) `num' was not declared in this scope
    3) expected primary-expression before "struct"

    Can you help me with this minor problem?

    I think post #3 already gives the answer.

    Oh my god. I made huge red text to show you which code has an error after compiling. Coding size has nothing to with error.

    Perhaps by num you meant "int"?

    It's a tough house sometimes
    C programming resources:
    GNU C Function and Macro Index -- glibc reference manual
    The C Book -- nice online learner guide
    Current ISO draft standard
    CCAN -- new CPAN like open source library repository
    3 (different) GNU debugger tutorials: #1 -- #2 -- #3
    cpwiki -- our wiki on sourceforge

    As i followed what MK27 told me about "num" to "int". I changed it. Again i got an error with this code
    Code:
     inPut = getNumber();
    How to change this? Instead of this what would be the new code.

    Thanking You

    I don't suppose you could happen to remember WHAT ERROR you got? Those little word-thingies actually tell you what's wrong if you read them.

    first thing... inPut is declared as num. I hope you have changed it to int.
    second getNumber declaration void getNumber(void); it is not matching with the way you are using..

    your declaration should have num/int getNumber(void). Give a return inside the function.

    Third from next time when you post, give the compiler error too. That will make the job easy.

    the errors are:
    1) In function `int main()':
    2) void value not ignored as it ought to be
    3) [Warning] unknown escape sequence '\>'

    Now what to do.

    You have to use \\ if you want to have a \ in a string.
    Code:
    printf("\n\n Enter Index value \n\t C:\> ", STR_SIZE);

    Still there is a problem with this code
    Code:
     inPut = getNumber();
