i got an error in project "snake" its near 700 lines so i cant copy all of it. but the problem is the compiler gives me "length" is not a type.and its kinda weird.the language is "c"


"""""

struct snake_place
{
    int x ;
    int y ;
};

struct snake_data
{
    int length ;
    struct snake_place snake_array [50] ;
    struct snake_place head ;
    struct snake_place tail ;
    int direction ;
};
struct snake_data snake;



.........
........
void shift1(){
    int i;
    int snake,length,snake_array;
    int snake1;
        for (i = 0 ; i < snake1.length - 1 ; i++ ){
        snake1.snake_array[i] = snake1.snake_array[i+1] ;
        }
    }
 """""

in void shift1() there is an error i cant solve.and im in a hurry...

Reason for edit:: Added missing code tags. Please learn to use them properly.

I'm not sure why you get the error message you do (presumably the piece of code that causes that error message isn't part of the code you've posted), but snake1.length doesn't make any sense since snake1 is an integer, not a struct or union that has a length field.

PS: Next time it would be great if you posted a small code sample that produces the error message you're asking about when compiled and if you posted the whole error message including line numbers.

wow what a mistake!!!! i think u r right tnx for quick answering.i will correct it and see what happens..

[hamidooooo]

i have a really hard situation.i wrote about 700 lines in "c" language and have some errors in my program.i will copy my whole game here and im in a hurry too.if someone could correct it for me.u can copy it into your compiler and see the errors.my compiler is dev++.heres is my code.please answer me quick and compelete.tnx.

line 5 turns into smilies so i correct it :

#define max3 ( a , b , c ) ( ( a ) > = ( b ) ? ( ( a ) > ( c ) ? ( a ) : ( c ) ) : ( ( b ) > ( c ) ? ( b ) : ( c ) ) )

[jimblumberg]

If you have compile errors please post the complete error messages exactly as they appear in your development environment.


And in future please use code tags when posting code!

[undefined behaviour]

Did you notice the background of the textbox you wrote your message into, telling you to "Please put [code] tags [/code] around your code!"?

Did you notice it also says "Don't tell us to give you code! We won't do your homework for you. Tell us what errors you're getting. Tell us what you've tried/searched for"?

No. I'm waiting quite patiently for these requests to be fulfilled. Let me know when you actually want help.

im very sorry.im new here and dont know the rules yet.i will do what u said next time.and i dont want u to do my homework.i have some errors and dont know how to fix them.

most of them are "is not a type error" and i think somthing isnt right about my structure.i tried to fix this and put a "snake" struct" in it and i have got some new errors!!!!

Please don't create new topics for an existing problem. You already have an open topic so use that. Topics merged.


For the first problem start by looking at the function where your error message told you it detected the problem, namely

Quote

In function `void shift1()':

Now the function in question:

void shift1(){
    int i;
    int snake,length,snake_array;
    int snake1;
        for (i = 0 ; i < snake1.length - 1 ; i++ ){
        snake1.snake_array[i] = snake1.snake_array[i+1] ;
        }
    }

Look closely at your variable definitions, snake1 in particular

Then re-examine your error message:

Quote

error: `length' is not a type
error: request for member of non-aggregate type before '-' token
error: `snake_array' is not a type
error: request for member of non-aggregate type before '[' token
error: `snake_array' is not a type
error: request for member of non-aggregate type before '[' token

First what type of variable is snake1? Is it a structure, a double, a char, or is is maybe a simple int?

Next look at snake_array is that variable actually an array? Or is it possible that it is just a single int?

You seem to be using global variables, which is a bad practice by the way, and then naming local variables the same as those global variables. Doing this hides the global instance and uses the local instances. This seems to be one of your big problems, that and you don't yet seem to have a grasp of the different type of variables.


But the biggest problem seems to be that you waited much too long to compile your program. By waiting so long you have created quite a few problems that you must try to fix. If you compile your program after adding just a couple of lines of code then your number of errors will be much less and you will know exactly where to start looking for the problems.


I suggest you revisit your class notes, textbook and other sources for information on how to properly use structures. This seems to be your biggest problem, you don't understand how structures work. Also you may want to learn how to properly pass variables to and from your functions, to eliminate the global variables. The function tutorials contained in my signature may help with learning to properly use functions.
