Basic Order booking program for a Restaurant ....

Hello again ....

I have written a Basic program of an assignment on "Functions" related to a Restaurant Order Booking system.

I am facing following two problems in it :

1- I want to clear screen every time after a user's input so that the Screen related to User's input only show. What should I do to perform it?

2- While selecting Zero (0) to jump back to Main Menu from Sub-Menu, the program works perfect. But after selecting Sub-Menu Card option, the program only shows the Input Option and not reflecting complete Sub-Menu Card option before it. I couldn't understand what I am lacking here ..... !

I am providing the Program Code below and would be thankful if anyone of you point-out the missing error to run the program correctly.

Code:

Just as a thought, what would happen if the menu was expanded and customers had the choice of 512 different meals?

The predicament this would present is (probably) not your fault but your teacher's fault. I hate the stupid menu programs. Nobody has programmed this stuff for a long, long time -- basically because it's a waste of time.

Edit: I'd like to amend my statement. Nobody has ever written code like this because, essentially, back in ye olden days there was no RAM to write code like this. Please ask your teacher to contact me. Thanks.

Edit 2: I'm sorry if I seem to be in a non-supportive mood but I'm tired of seeing crap like this (not your fault!) being constantly, over and over and over and over, being posted on this board. This kind of program isn't "programming", it's just rubbish. You've wasted a lot of time to write 460 lines of code that I'm sure your teacher may like but it's just not how things work.[/rant]

Edit 3: I'll have the Thai Soup

Thanks Hodor for your comments ..... I think you didn't see the subject line which clearly specify the word "Basic".

I would say that it is a program written by a person who is new to C++ programming and have completed only few chapters in just two weeks time. Moreover, it is a practice program of Functions with little knowledge of programming.

Oh, I saw the keyword "basic". For 500 lines (give or take) what have you learned? The if statement (unfortunately not else if which is probably why your program is broken) and while. This has nothing to do with you, maybe you find the menu exercise exciting! It's about teaching. This huge assignment is aimed at teaching you two very basic concepts in a very unrealistic way. I'm sorry, I just find it absurd that people would assign homework like this.

And after this 500 lines of code I wager you still don't know what was taught (well, not taught) -- flow control.

FAQ > Clear the screen? - Cprogramming.com

Code:

---

    int mainmenu;
    mainmenu = (1,2,3,4);
 
 
    int submenu;
    submenu = (0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18);

---

Those assignment statements don't do whatever it is that you think that they do. Essentially all you are doing here is assigning 4 to mainmenu and 18 to submenu.

Code:

---

while (0);
      {

---

Two problems here. 0 is false in C/C++ and so while(0) will result in the body of the loop never being evaluated. This can have some uses but as you don't seem to have any labels inside the loop I'd say that it is an error. Additionally the body of the loop is only the empty statement ( ; ) and so it isn't having a significant effect on your program. The two errors kind of cancel out.

I'm not sure why you're expecting your program to go back to the main menu when you haven't programmed it that way. You are displaying the menu again and then getting input but you're not dealing with that input. A better way would probably be to have your submenu loop inside your menu loop I suppose. To be honest though I'm kind of having a hard time bending my mind around what you are supposed to do so that could be wrong.

Code:

---

if (submenu > 18)
            {
                nextline();
                cout << '\t' << "PRESS ZERO ( 0 ) TO RETURN BACK TO MAIN MENU \n";
                nextline();
                cout << '\t' << "PRESS ( 18 ) TO EXIT AND PRINT YOUR ORDER \n";
                nextline();
                cout << '\t' << "PLEASE PLACE YOUR ORDER HERE : ";
                cin >> submenu;
                nextline(); nextline();
            }

---

This code is redundant/duplicate code.

@ Hodor:


Don't blame the teacher, just blame me because I don't have any teacher. I am learning C++ from the Book "Jumping into C++" by myself. And I have just finished sixth Chapter learned only few basics e.g., Conditional Statements, Loops and Functions.


On the basis of it, I tried to accomplish my assignment given at the end of Chapter-6.


I thought this platform is meant for learning and sharing knowledge to/with others. However, if my stupid Codes/Program really so much annoyed you, I won't put such rubbish codes/crap on this board in future where such an intelegent people like you exits.


Meanwhile, I would sugges just to copy the codes and run them into your Compiler twice. Firstly without using the Input Zero and
secondly with the Zero Input. You would definitely notice that the program didn't broken rather at first time the program would run perfectly till the end. However, at the second time the program would also run till the end but it won't show the Sub-Menu Card either.




@ DeadPlanet:


The problem is not with the int mainmenu or submenu code.


If I would use While (1) in my loop, the program would stop at first stage and never goes beyond it. That's why I used While (0).


I have checked to input submenu loop inside menu loop, but it didn't work either.


The,

Code:

---

if (submenu > 18) { ..... code .... }

---

, is not redundant/duplicate code. Rather, it would revalidate or check the wrong input of user (if he/she input the value greater than 17).


I have also detected the problem relates to my codes/program i.e, I have set mainmenucard functions outside the main block whereas I put/call the said function 2nd time within a submenu loop that's why the program only perform as per instructions set therewith.

You completely missed the point here. In your code, this is the whole entirety of your loop:

Code:

---

;

---

That's not much of a loop. If you want that while loop to actually loop, you need to remove that semicolon after "while" so that the curly-brace block becomes your while loop. (A while loop consists of the very next thing after the word "while", and you have a semicolon as the very next thing, so that's all the loop you get.)

---

in fact, just the opposite is true. while (0) will not execute the loop even once. while (1) will execute forever, or until a break or return statement is encountered. if the condition inside the parentheses of a while statement evaluate to false (0 is false), the loop stops. your problem is the semicolon after the while (0).

@ tapstop: Yeah .... you right. Basically, first I used do - while loop but later-on I deleted do and only used while loop. But, unfortunately, I didn't delete semicolon from the while loop. However, when I deleted semicolon and put (1) inside while loop and then run the program, the loop became infinite loop.

Which will also occur without that code when the program returns to the start of the containing loop...

OK .... I have changed the code as:

Code:

---


else if (submenu > 18)
            {
                nextline();
                cout << '\t' << "YOU ENTERED WRONG VALUE ... PLEASE TRY AGAIN : ";
                cin >> submenu;
                nextline(); nextline();
            }

Thanks God ..... I have corrected the problem with the help of you people and are reproducing my codes again .... its perfectly running.

Edit: You may try it by yourself in your Compiler.

And special thanks to DeadPlanet for pointing out the errors in my codes and resolving my problem.

Actually, your functions all return a char, or so you've told the compiler, but you are in reality not returning anything. That's an error. This will not compile on some compilers.
You probably meant that the function should not return anything, so you should change their return type to void.
