对现有数据生成随机序列

/*对现有数据生成随机序列*/#include<iostream>#include<ctime>#include<cassert>using namespace std;//现有数据规模#define N 16int main(void){int iArr[N][2];for (int i = 0; i < N; i++){//第0列存放数据iArr[i][0] = i;//第1列存放标志,1为未读取,0为已读取iArr[i][1] = 1;}srand(unsigned(time(NULL)));//生成随机数列的组数for (int j = N; j > 0; j--){//初始化数据状态for (int i = 0; i < N; i++){iArr[i][1] = 1;}//time_t startTime = time(NULL);for (int i = N; i > 0; i--){//生成随机数int index = rand() % i;//查找从改位置起，状态位为1的数据下标while (iArr[index][1] == 0){index++;}assert(index < N);//打印改位置数据，并把状态位置0cout << iArr[index][0] << " ";iArr[index][1] = 0;}//time_t endTime = time(NULL);cout << endl;}return 0;}
