How to allow the rand() in the

Because sometimes I wanted to rand () to generate numbers over 32767. Is there have a way to extend the limit of rand() and can generate a larger random number for my program. An example:

#include <cstdlib>
using namespace std;


int main() {
    srand(9439);
    for(int i = 0; i < 15; i++){
        cout << 1 + (rand() % 500000) << endl;
    }
    
}

So, the result never goes beyond 32767. Is there have a way to let rand()generate random numbers over 32767?
