I supposed to make in memory linked list. I thought I did it perfectly. My teacher is kind of the teacher that won't teach you but let you figure it out.. I couldn't figure it out!!! I supposed to make one like this but to manipulated the list. I am losing here...

what is "/var2/local/include/getch.h" ?

where is phere declared ?

How can I delared it? :-/

How can I delared it?

#include "getch.h"

assuming this is your struct

struct myStruct{
       //details
}

typedef myStruct phere;

Because you havent formatted your code very well, you missed out a curly bracket during your switch statement. I have formatted and made the following corrections for you:

Well spotted :) I gave the more obvious problems

I am thanking all for the help. I appreciate it so much. I couldn't find a better teacher than you guys. With your advices and corrections, I still get thos errors??

Look at williamhemswort 's post again (line 49). Did you add that ending bracket } ?

Yes... I did. Nothing is working. I am having a Programmer's Block :'(

then what errors are you getting..can you repost your edited code

you have not read through all the posts here.. i can see this piece of code was already corrected from this

case 'e':
				if(!p) {
					p = new prs;
					if (!p) exit(-1)
					p > next = p > prev = p;
					edit_rec (p);
				} else {
					phere = p > prev;
					pnew = new prs;
					if (!pnew) exit(-1)
					p > prev = pnew;
					pnew > next = p;
					phere > next = p;

to this

case 'e':
				if(!p) {
					p = new prs;
					if (!p) exit(-1)
					p  ->  next = p -> prev = p;
					edit_rec (p);
				} else {
					phere = p -> prev;
					pnew = new prs;
					if (!pnew) exit(-1)
					p -> prev = pnew;
					pnew -> next = p;
					phere -> next = p;

Note the changes in red. I have not corrected the code for it to work but I am just pointing out that maybe you have not done as suggested

error C2143: syntax error : missing ';' before '%'

There isn't a '%' in this program, this error is probably from the getch.h file. Please post the code as Ancient Dragon requested earlier.

Since joshmo pointed out my simple mistake... I changed but Visual Studio started to hate me because it threw me 55 errors on the complier. I edited the code asn it showed below:

There are actually a couple of semicolons missing from Joshmo's correction, for starters you might change both if (!p) exit(-1) to if (!p) exit(-1) [B];[/B] and then recompile and post the new errors. Most probably you are receiving most of the errors due to the "/var2/local/include/getch.h", so you might post that file also. (I take that e.g. 'phere' and other related things are declared there(?))

Thanks but the errors are still same. Even though the semicolon is missing from the prevous.. The most errors came from "unknown characters"

Well, given the code you've posted this far, makes it impossible to figure out further what goes wrong ... for one example, what is 'phere'? Is it something that you have in "getch.h"?

How exactly I can introduce "phere" in my code? I tried the "#include getch.h" but it won't help me at all

I assume that in some file you have for example something like

// struct or class named prs
struct prs
{
    // something here
};
// a function which takes a pointer to prs
void edit_rec (prs * p);

maybe 'phere' appears also there, so you might post that file (at least).
