Lvalue required in function main

**arjay** · 09-30-2008

am....first of all i just would like you to all to know that im just a beginner in C programming so please understand if my codes to loooong whe've just discuss
about arrays, pointer, and functions last week.......

here's my code with an error:

Code:

                                                case 1:order="Strawberry Sundae";break;
			case 2:order="Hot Caramel Sundae";break;
			case 3:order="Hot Fudge Sundae";break;
			case 4:order="Vanilla IceCream";break;
			case 5:order="COke Float";break;

Our prof wants us to make a program that receives orders in a fast food chanin
and display a receipt complete with all info and the orders.....

i have already written the code but my problem is that it only prints the last order i've entered it is supposed to print all orders T_T

and i've decided to use an array of strings to store all the orders and call it at the receipt part to print all the orders it stored..

declaration:

Code:

                char order[50];  // i've stored all order in the variable order
	char or[]={ };

here the part to store the orders in the array:

Code:

                for(r=0;r<100)
		{
			or[r]=order;
			r++;

		              other:
		              clrscr();
		              getch();
		              gotoxy(26,12);textcolor(YELLOW);cprintf(" Do u hav another order? [Y/N]");
		              gotoxy(26, 13);textcolor(YELLOW);cscanf("%c", &ans);
		                if(ans=='y' || ans=='Y')
		                 {
		                		clrscr();
				                goto category;
		                  }
		                  else 
				goto sub;

here the part to print all the orders:

Code:

		for(j=0;j<100;j++)
			printf("%s",or[j]);

i really need ur help guys T___T
thanks

Code:

or[r]=order;

This is not how you copy strings. This is trying to copy a pointer into a single char and your compiler should be screaming its head off when it sees this.

Also, get rid of the goto's. As far as students are concerned, goto is EVIL and should never be used. Plus your teacher should be complaining if he sees them in your code.

Code:

order="Hot Caramel Sundae";break;

Nor will this ever work either.
order is an array, but you assigning (or trying) a const char* to it.
You need to copy a string? Use strcpy.

And just for curiosity, how does your main look and your input (code)?

ill understand if you'll scream by the time you saw my code T_T
thanks......

by the way does my

Code:

char or[]={};

still needed??

base on your replies your telling me
to use strcpy to print the orders stored on my variable order
am i right?? 0_o?

**Elysia** · 10-01-2008

Well... wow.
You need to rework this code a little!
First off, indentation is off in bits and pieces. What editor / IDE do you use?
Second, you should have a read: http://cpwiki.sourceforge.net/Implicit_main
And thirdly, as someone has already mentioned, you should get rid of all the gotos. Use different loops instead. You'll be surprised how much easier to read the code becomes!
And those if / else if cat == N could be replaced with a switch.

There is no need to keep calling textcolor(YELLOW)

Call it once, and then everytime you want to change the colour. And you haven't really used arrays or pointers at all, this could be about 1/5 of the size if you did. Don't you think it seems odd you learnt about them last week, but you haven't used them yet!?

**arjay** · 10-01-2008

am im not really using any editor...i just write my code in a notepad an save it as a .c file ^^

BTW thanks Elysia for the big help ^__^ it really enlighten me hehehe...

oh i just would like to ask....

in my program there are lots of choices and that choices are limited to let say from 1 to 5... so ive use an

Code:

if(cat>5 || cat<=0)

but when i enter a letter it'll crash or go crazy
what will i add or do so that it will not go crazy each time i enter
something thatdont correspond to the chocies??

please help me T__T
thanks

Your tests are fine.

You should concentrate on cscanf("%d", &cat); which may fail if you enter a letter. The value assigned to cat is, well, not assigned. So cat can be any garbage.

cscan returns a number of arguments that were matched... You should check that and yell at the user if required.

No, you shouldn't.
That's what editors and IDEs are for.
Notepad is the worst possible place to write code.
