新的编码和我卡住了，需要使一个数组，存储5个数字（1-9），然后我需要检查该数组是否有重复如果有重复，我需要用一个全新的随机行来替换该数字，没有重复（似乎是更容易的选择）或者只替换那个数字，之后想让我让用户5个数字猜测存储在一个数组中，在底部显示数组沿着在每个数字下显示这些值
//* =表示数字位于确切位置
//- =表示数组不包含该数字
//+ =表示数组包含数字但位置不正确
所有的数组都希望一次输入一个数字，重复步骤，直到用户得到所有的数字，然后用完成消息结束游戏。
我真正的问题在于步骤4和步骤7;下面是我今天一直在工作的代码，但任何帮助都将是真正的感谢

#include <iostream>
#include <ctime>
#include <cstdlib>
using namespace std;
void game_instructions(int n);
bool search_array(int a[], int n, int t);
int main()
{

    //Step 1: Declare your variables and constants
    const int SIZE = 5; //this constant stores the length/size of the code

    int randcode[SIZE]; //this array stores the code generated randomly by the computer
    int guess[SIZE];    //this array stores the code inputted by the player/user
   
    //you may add more variables as needed
  
    //Step 2: Output game instructions by calling function game_instructions
    game_instructions(SIZE);
    //Step 3: Generate a random code and store it in the array randcode one digit at a time.
    //Each digit should be between 0 and 9 and should be stored as one array element
    //Recall that rand() % 10 can be used to generate a number between 0 and 9
    srand(time(0));
    for(int i=0;i<SIZE;i++)
       randcode[i]= (rand() % 10);  //Computers random 5 numbers generated
   
    cout<<"\nRandom C-numbers::"<<endl;
   
    for(int i=0;i<SIZE;i++)
       cout<<randcode[i] << " ";
    
    //Step 4: Repeat step 3 if the array randcode contains duplicates
    //You must use function contains_duplicates to implement this step
    
    
    
    //Step 5: Ask the user for his guess and store it in the array guess.
    //Read one digit at a time, validate it to make sure it is between 0 and 9, and store it as one array element
       
    for (int i=0; i<SIZE; i++) {
        cout<<"\nEnter Digit "<< i+1 << ": ";
        cin >> guess[i];}
            
    cout << endl;
    //Step 6: Output the array guess on a single line with a space after each element (see the sample output provided)
    for (int n=0; n < SIZE; ++n) {
        cout << guess[n] << "  ";
    }
    //Step 7: Compare the randomly generated code (randcode) with the user's guess (guess)
    //and display feedback for each digit as: *, + or –, as explained below:
    //For each digit in the user's guess do the following:
        // If it matches the digit from the random code (both value and position), output *
        // Otherwise, if it appears anywhere in the random code, output + (use function search_array here)
        // Otherwise, output -
        
    //Step 8: Repeat steps 5,6,7 until all digits have been guessed correctly
    
    //Step 9: Output congratulations message
    cout << endl << endl;
    cout << "Good job! You guessed the code!";
    return 0;
}

void game_instructions(int n)
//This function outputs the game instructions.
//Its parameter n represents the length of the code.
{
    cout << "A random " << n << " digit code has been generated. You have to guess it. \n";
    cout << "For every digit you will receive feedback in the form of *, + or -  \n";
    cout << "   * means the digit is in the code and it is in the correct position.\n";
    cout << "   + means the digit is in the code but it is not in the correct position.\n";
    cout << "   - means the digit is not in the code.\n";
}

bool search_array(int a[], int n, int t)
//This function searches the array a (of size n) for a target value t.
//If t is found in the array the function returns true; otherwise it returns false.
{
    for (int i = 0; i < n; i++)
    {
        if (a[i] == t) return true;
    }
    return false;
}

bool contains_duplicates(int a[], int n)
//This function searches the array a (of size n) and returns true if the array contains duplicates; otherwise, it returns false.
{
    for (int i = 0; i < n; i++)
    {
        //compare element a[i] with all the remaining elements from index i+1 to n
        for (int j = i+1; j < n; j++)
        {
            if (a[i] == a[j]) return true;
        }
    }
    return false;
}

我得到了大部分的侧代码完成，但我只是难住了如何让这个数组匹配任何帮助将是很好的
