随机数发生器即使在播种后也会生成相同的数字

Random number generator generating the same number even after seeding

这是我的代码：

#include <iostream>
#include <string>
#include <random>
#include <ctime>
using namespace std;
int RandomIntGen(int lowerLimit, int upperLimit);
int main()
{
    for (int i = 0; i < 10; i++) {
        cout << "I am rolling a " << RandomIntGen(1, 6) << endl;
    }
    system("PAUSE");
}
// A random integer generator that takes in a upper and lower integer limit and returns a random integer
int RandomIntGen(int lowerLimit, int upperLimit) {
    default_random_engine randomGenerator(time(0)); //seeding with time
    uniform_int_distribution<int> randomInteger(lowerLimit, upperLimit);
    return randomInteger(randomGenerator);
}

不知道为什么即使在播种中也会产生相同的值。我该如何解决？

移动" default_random_engine RandomGenerator(time(time(0((;"到全球空间以确保仅播种一次。

#include <iostream>
#include <string>
#include <random>
#include <ctime>
using namespace std;
//Random Generator with Seed
default_random_engine randomGenerator(time(0));
// Function Declarations
int RandomIntGen(int lowerLimit, int upperLimit);
int main()
{
    for (int i = 0; i < 10; i++) {
        cout << "I am rolling a " << RandomIntGen(1, 6) << endl;
    }
    system("PAUSE");
}
// A random integer generator that takes in a upper and lower integer limit and returns a random integer
int RandomIntGen(int lowerLimit, int upperLimit) {
    uniform_int_distribution<int> randomInteger(lowerLimit, upperLimit);
    return randomInteger(randomGenerator);
}
