Thread: Beginner!

Hello!

I'm trying to make a bulls function! On average I would like it to hit the Bull 70% of the time and the other 30% (miss) between 1 to 20. As you can see I have the basic code, but I'm just learning so don't really understand what each part does.

Code:

int Bull() 
{
        int percent = rand()%100; //lower percent is more throws needed
        int r = rand()%100; //lower r is less throws needed
        if(r<percent)        // hit
        return 50;
        else            // miss
        return 1 + rand()%20;
}

Thanks in advance! :-)
