C++编写生成不重复的随机数代码

 vector getRandom(int total) { srand((int)time(NULL)); std::vector input = *new std::vector(); for (int i = 0; i  output = *new vector(); int end = total; for (int i = 0; i ::iterator iter = input.begin(); int num = random()%end; iter = iter+num; output.push_back(*iter); input.erase(iter); end--; } return output; } 

 void permutation(int n, int *z_array) { int i, j, k, z; int buffer[N]; /* 初始化数组 */ for (i=0; i

 #include #include  #include "iostream" #include  #define N 53 using namespace std; //print array void display(int *a) { for (int i =0;i
