[Black cpp]

#include <iostream>
using namespace std;
int main()
{
int x =rand(%9)+1;
cout << x ;
return 0; 
}

it shows always the same NO. each time i run the PROG.
can i have help as fast as possible

Yep. You forgot a little something that will permit the rand()s to return random numbers.

Have fun!

P.S: Check line 5.

[Black cpp]

whats wrong with line 5
i cant see any problem

[Albatross]

If you compiled it, you'd know. :P You need to move the %9 over to the right a bit...

ok that's right.
can u give me the correct code.
thx :D

What? Is it that hard to just make the small change yourself...?

In your other post you wanted to be an expert. You can't be too dependent to others. remember that % takes left and right operand like so.. 5%3=2, left is 5, right is 3.

noooo i mean write a code doesnt print the same number each time i run it

[Albatross]

You need to put something between lines 4 and 5. See the link I gave for a hint as to what it is.

I'm in a very helpful mood today... >_>

Oh, by the way...
forum::members.user("blackcoder41").last_post_in_thread(33723)+=std::numeric_limits<forum::user_post_value>::max();
If you want to be an expert, learn to do things yourself. We'll help you as much as we can and are willing to, but for you to get better, you need to be able to make us superfluous (did that sound wrong?). :)

#include <iostream>
using namespace std;
int main()
{
srand(time(0));
int x =1+rand()%9;
cout << x ;
return 0;
}
