Help using random numbers

[Smatik]

i had the following problem in my book:

#include<iostream.h>
#include<conio.h>
#include<stdlib.h>
void main()
{
    clrscr();
    randomize();
    int Game[]={10,16},P;
    int Turn=random(2)+5;
    for(int T=0;T<20;T++)
       {
           P=random(2);
           cout<<Game[P]+Turn<<"#";
       }
getch();
}

The output comes like 16#22#16#16#16#22#....20 times... Why the output of this always comes either 16# or 22#?? why not 15# or 21#?? i would like to the mechanism of this program. Thanks. turn=random(2)+5; if random(2) gives 0 then turn becomes turn=0+5=5 which implies that i should get 10+5=15 and 16+5=21 along with 16 and 22 but i m not getting them.

We got the above question in our computer science theory exam and we were to chose the correct answer(i.e it generates 16 and 22) but how will i am going to know that it will generate only 16 and 22. As i explained above 15 and 21 are also possible..

Seeding was required

#include <ctime>
and use srand(time(0));
to Seed RANDom numbers!

void main()

Get rid of that crappy book.
