line 12: its int main().

The rest is just too difficult to read because of terrible formatting. Don't be afraid to use some spaces to indent lines.

Your code looks kind of crazy. I don't understand any of this, why would you need 6 variables just to create a simple array with that serie? I don't get it.

 void displayArray(int nArray[])
{
int b;
printf("%d",nArray[b]);
}
 void displayArray(int nArray[])
{
int b;
printf("%d",nArray[b]);
}

Why would you want b for? And by the way it isn't initialized so you'll print random memory stuff there.

Anyways I strongly recommend you to throw all that code away, even if it's working, and write us a pseudocode of how you want your program to run, and we will work by there. If you don't know what pseudocode is try google it. Now is the best point to start for you in my opinion.
Seriously.

Seriously.

HOw would you initialize b, since if you initialize it in the function then it will constantly keep b at the same number. However if i initialize it in the program it will still keep b at the same number.
here i indented the program. Here is it reposted

Ok, you didn't pay attention to my first post trying to help you, so just answer this one.

Do you want us to fix your code or do you want to learn how to fix it by yourself?
