C++ 生成随机数

#include <ctime>#include <algorithm>#include <vector>using namespace std;int _tmain(int argc, _TCHAR* argv[]){srand((unsigned)time(NULL)); //设置随即数生成器的种子  vector<int>vData;for (int i = 0; i < 10; i++){vData.push_back(i);}random_shuffle(vData.begin(), vData.end());random_shuffle(vData.begin(), vData.end());return 0;}

加了时间因子，每次随机排序都不一样
