Language?

Assuming c/c++, there is no standard way of clearing the screen.

You could choose to use someting like system("cls") in windows and system("clear") in unix...

There are probably ways of doing thisin code to rather than using another program.


For random numbers, you would want rand().

you need to use srand( seed ) to change the seed which will dictate the sequence you are going to get. You can use the time function with NULL as a paramenter to get a suitable "random" seed.

Here is a sample:


I can' t remember the headers exaclty, I think its:

#include <cstdlib>
#include <ctime>
using namespace std;

for c++ and:

#include <stdlib.h>
#include <time.h>

for c.
