A problem with the random library in functions

When I use the random library in functions it doesn't work well at all. it prints inncorrect things like : This and this but if I am not using functions it works completly fine.

I tried to create a function that returns the value of the random number but it fails and prints something weird

Works good:

#include <iostream>
#include <random>
#include <string>
using namespace std;
int main()
{
    random_device rd;
    mt19937 number(rd());
    uniform_int_distribution <>random(1, 3);
    int num = random(number);
    cout << "The computer choose: " << endl;
    if(num == 1){
        cout << "one" << endl;
    }
    if (num == 2) {
        cout << "two" << endl;
    }
    if (num == 3) {
        cout << "three" << endl;
    }
    cout << num; // to check the real number

Doesn't work good:

#include <iostream>
#include <random>
#include <string>
using namespace std;
int random(int num);
int main()
{
    int num = 0;
    cout << "The computer choose: " << endl;
    if(random(num) == 1){
        cout << "one" << endl;
    }
    if (random(num) == 2) {
        cout << "two" << endl;
    }
    if (random(num) == 3) {
        cout << "three" << endl;
    }
    cout << random(num); // to check the real number
}
int random(int num) {

    string call;
    random_device rd;
    mt19937 number(rd());
    uniform_int_distribution <>random(1, 3);
    num = random(number);
    return num;
}
