#include <iostream>

using namespace std;

int main()
{	
	double randomMax = 0.0;
	int rand_max = rand();

	//calculate rand_max
	randomMax = 0 + rand_max;

	//display the value of the RAND_MAX constant
	cout << randomMax << endl;


    return 0;
}   //end of main function

The problem is I'm only getting 41 as the number, which I know isn't correct.
