How to make this program work by changing the ouput and operator function ?

#include

using namespace std;

unsigned int seed = (unsigned int)time(0);

}

void initialize_vector(vector &v)

{

it -> value =(10 * random(seed));

}

}

void print_vector(const vector &v)

{

}

{

return double (seed) / double (MODULUS);
