error
L.12: array size too large
L.19: too much global data define in the file

There's a limit to how big your data structures can be.

Since MAX is 10,000 you are asking for an array of
10,000 x 10,000 x sizeof( int ) bytes
which is likely about 400,000,000 bytes, which is nearly a half a Gigabyte!

Either make a smaller array, or google "sparse arrays" and "sparse matrices" and "hash tables".

Good luck.

thanks, but since i convert this code from C++ to C can you tell how can i do it,

why do you need such huge arays? The calc function at line 97 only uses a 30x30 array.

What compiler are you using? From the errors you posted my guess is that you are using ancient/fossile such as Turbo C. Use a modern 32-bit compiler such as free Dev-C++ or free VC++ 2005 Express and you will not get either of those errors.

There are also quite a few syntax errors in the code you posted. It appears to have been originally written with a c++ compiler. Changing to a C compiler will require some rewriting to conform to C standards. Examles: in main() move all data declarations to the top of the function and remove them from the for declarations. The newest C standard permits declaring objects in other places like c++ does but not very many compilers support that yet.

I just noticed that the code you posted also uses c++ class that you will have to rewrite with C linked list. See line 136.

thanks alot, i must use turbo C, and i try to move all data declarations to the top of the function but i have many problems, can you show me how??
