srand () with rand () generates a random number

srand () with rand () generates a random number

After the test, when the value of srand determined, the corresponding values ​​are determined of the rand.

 

#include <iostream>
using namespace std;
int main()
{
    for (int i = 0; i <= 10; i++) {
        srand(i);
        cout << "当seed = " << i << "时，其结果为：" << rand() << endl;
    }

    cout << endl << endl << "------第二次验证---------" << endl << endl;

    for (int i = 0; i <= 10; i++) {
        srand(i);
        cout << "当seed = " << i << "时，其结果为：" << rand() << endl;
    }
}
