在C++中生成不同的随机数

对于编程作业的一部分，我需要生成多组 10 个数字，范围为 1 到 50，每个单独的集合中没有重复，因此我创建了以下代码：

int Numbers[10]; //array to store the random numbers in
bool Duplicate; //variable to check or number is already used
srand(time(NULL)); //seeding the random number generator
// do while loop used to allow user to generate multiple sets 
do {
     Duplicate = false; // set check to false
     //for loop to generate a complete set of 10 random numbers
     for (int I = 0; I < 10; I++)
     {
        // do while loop used to generate random numbers until a distinct random number is generated
         do
         {
         Numbers[I] = (rand()%50) + 1; // generates a random number 1 - 50 and stores it into Numbers[I]
         // for loop used to check the other numbers in set for any repeats
         for (int J = I - 1; J > -1; J--) // works backwards from the recently generated element to element 0
              if (Numbers[I] == Numbers[J]) //checks if number is already used
                   Duplicate = true; //sets Duplicate to true to indicate there is a repeat
         } while (Duplicate); //loops until a new, distinct number is generated
     }
//at this point in the program we should have an array Numbers[] with a set of 10 unique random numbers 1 - 50
     // loop to print numbers to the screen
     for (int I = 0; I < 10; I++)
          cout << Numbers[I] << " "; // printing the element to the screen
cout << endl;
cout << "Do you want to run the program again (Y/N): "; // Asks user if they want to create another set of 10 numbers
char Answer; // used to store users answer
cin >> Answer; // stores users answer
} while (Answer == 'Y' || Answer == 'y'); // loop program if the user wants to generate another set

但是，我似乎在使用生成随机数的 do while 循环时遇到问题，直到生成新的不同数字。经过一些测试和修补，我发现我以某种方式在那里创建了一个无限循环，无法找出问题所在。

我认为可能导致问题的一些想法：-rand 函数如何更改种子，是否更改种子以创建新的伪随机数？-我的 for 循环是否用于检查重复是否超出数组的边界？

任何建议和提示将不胜感激。
