Hi,
I'm working with a code that I wrote for knight tour. After I resolved all the errors I tried to run the program, but it doesn't stop to show the result like an infinite loop.

		for(c=0;c<s;c++)
		{
			for(d=0;d<s;d++)
				cout<<setw( 2 )<<cb[c][d]<<" ";

			cout<<endl;
		}
			cout<<endl;
	}

	system("pause");
}

Does anyone know what the problem is?
Any help is welcome.

Cheers,
Domo

Have you tried debugging it?

yes , but there is no bug in the software and and although i couldn't find any infinite loop , it keeps running with no result and no stops

Well, it would help if the variable names even somewhat described what they are doing. Looking at this, it almost looks like a coded message.
