C++ array of random numbers [duplicate]

• How to generate different random numbers in a loop in C++? 12 answers

I am looking for a simple way how to generate a vector of random integer numbers in a specified range (in my example 0 or 1) in c++. I have looked for possible solutions and implemented the most mentioned one:

vector <short> partition;   
for(int i = 0; i < 10; i++)
    {       
        srand( time(NULL) );
        int randNum = rand() % 2;
        partition.push_back(randNum);       
    }

However, as I've found later, this approach to generation of random numbers will generate different numbers if and only if it were called only once per second.

I've been searching for a satisfactory solution for a while now, I hope you can help me with this simple looking task.
