for(i=0;i<9;i++)
{
x[i] = rand()%9+1;
for(j=1;j<9;j++)
{
if(x[i]==x[i-j]);
i--;
}
}
pls tell me how the rand() function work. urgent. as soon as possible.

And that's all you need to know about that.

Now next time you post:
- use code tags
- Create a meaningful title
- Ask a clear question
- Don't use words like 'urgent'
hello. thanxs.
can u pls conform this equation : any no from 0 to 9 are used and after module and add 1 store in x[i]. pls reply.

And that's all you need to know about that.
Now for this:
If you hadn't waited for the last minute to start your homework, it wouldn't be urgent now would it?

What do you want? Do you want a random number between 0-9 or 1-10? How big is your x[] array? Where do you seed the random generator with
srand()? Last edited by niek_e; Nov 14th, 2008 at 5:20 am.
sorry for the disturb you. but i m big problem.
i make a sudoku game and for that i use this conditon to generate a random no bet o to 9.
i want to conform it takes a value by following code. i m new in programming. and donot know how to do this game. and i have only 4 days to complete it..

But I guess that this isn't your first assignment right? And you probably got more then 4 days to finish it, true?
So, again: If you started earlier, you wouldn't have a problem now.
thank u niek for the help. i started this game 3 days ago, but to develop a logic my time is spent. i m not complain to u. and i m not a student i m a flash developer. i m new in development. this is my first task, and that's why i want to do my best to complete it. b'coz first impression is last imperssion.

If you're new in programming and this is your first assignment and you only got 4 days to finish it, you should complain to your teacher, not me.
