This is a forum in which you can get help for writing your own code, not a service that provides code to you.

yup she's right.... narue can i ask where can i found a community that can help me... what community will accept all legal and illegal software making>>>???
tnx

jimmy try to learn first....

[Narue]

I don't know of any. The communities that support illegal software are typically full of script kiddies who aren't capable of or interested in writing something new, and communities that have qualified members typically find illegal software offensive. You're basically asking for two mutually exclusive features.

p.s. For anyone else interested in answering this question, naming a community and/or linking to it would likely be in violation of Daniweb's policies.

[jwenting]

Of course some communities may not officially allow illegal stuff but have admins who are either too ignorant or too lazy to police their sites properly.

If I knew of such communities I'd however not mention them...

[rafikul]

i am very new to c language.could you plz tell me how i proceed initially to make the soduko game..

[Phaelax]

Do you know about classes and objects yet?

[jwenting]

Seeing as the kid is talking about C, why should it know about classes and objects?
It doesn't seem interested in learning to program itself anyway, only in tricking people into giving it a complete solution it can turn in as the solution to its homework assignment so it doesn't get a failing grade.

here is a sample code in C++ soduko

	for(i=0;i<9;i++)
	for(j=0;j<9;j++)
	{
		cin>>K[i][j];
		k[i][j]=K[i][j];
	}
	cout<<"O.K.? (Enter 0 if OK, 1 to update): ";
	cin>>error;
	if(error==0)
		goto matrixvalidation;

matrixupdation:
	while(1)
	{

the code shows its worth in the 2nd line...

[technogeek_42]

the code shows its worth in the 2nd line...

what's the problem on the second line???

[Narue]

>what's the problem on the second line???
There are two problems:

1) Technical
The C++ standard specifies that the main function must return an integer. It has never returned void, as C++ is based on C, and C has never returned void from main. The void main issue was born of C dialects before it was standardized, and by that time too many people already had the habit of using void main. Thus, some compilers decided to support this style for convenience, which set a backward compatibility problem where void main will never go away.

By using void main, your code is not portable beyond the compiler you wrote it with. That's the real problem, but if you had no intention of portability, the only problem is personal (see below).

2) Personal
The problem on the second line (in that it shows the worth of the entire program) displays an elitist view of programming and a general disdain for anyone who doesn't hold language standards as the word of God. Using the problem on the second line to avoid reading the rest of the code is occasionally used as an excuse to avoid facing one's lack of understanding of other people's code. However, it's more often used as a weapon by language snobs to dismiss the efforts of beginners or anyone with whom the snob has a difference of opinion.

I was referring to the first post where he specifically asked for Java code, not the guy who attempted to hijack the thread.
