Answer 3

use rand() in c++ to get random number

ex -

#include<iostream>
using namespace std;
int main()
{
for(x=0; x<10; x++)
{
cout<<rand()<<endl;
}
return 0;
}

it will give you the random number. If You will use % then you will get random number in a specific range

Answer 4

I m not asking that
I mean suppose within range (1-10) it will give
1
4
6
5
and next time
2
9

7
and next time

10, only
no more outputs
never ever repeat no.
even I shut the system and run again
