Program with rand() func produces same results every run

Hi,

Basically I am working on a program that uses the rand() function to obviously produce random numbers. These numbers are assigned to various integer variables throughout the program.

The thing is, every time I run the program I get the same random numbers for each variable that calls the function - they never change. It's almost as if they are being stored somewhere in memory. Changing the name of the variable or putting it in a different place in the code will result in a different number generated, but that is hardly practical.

I am just wondering if there is something I am missing with its usage?

Any help is appreciated.

in the beginning of main, seed the random number generator:

Code:

---

#include<iostream>
#include<cstdlib>
#include<ctime>

int main()
{
        srand(time(0)); //seed the random number generator
                        //based off the system clock
        for(int i=0;i<10;i++)
        {
                std::cout<<rand()<<'\n';
        }
        return 0;
}

---

Thank you very much, it works fine now.

no problem :)
