我在使用随机整数填充数组，然后让用户尝试猜测数组中的数字的猜谜游戏时遇到了一些麻烦。我相信我的大部分内容都是正确的，但程序不会超出“正在初始化幸运数字...”打印命令，让我检查我的功能是否正常工作。我相信问题在于我如何将数组传递给函数，或者我如何调用函数（也许在它们的原型中？）任何帮助将不胜感激。这是我的第一篇文章，所以如果我无法正确包含代码，我深表歉意。谢谢！

uniqueFlag needs to be reset whenever you pick a random number, not just at the start of the outer loop in fillArray.

感谢大家！对于任何检查或遇到类似问题的人，我已经包含了我的更正。我能够在一个名为 checkArray 的单独函数中检查唯一数字，并通过从 fillArray 函数返回一个指针以及其他一些（包含的）调整来解决我的 fillArray 问题。

#include <stdio.h>
#include <conio.h>
#include <stdlib.h>
#include <time.h>


//Function Prototypes
int fillArray (int, int []);
int checkArray (int, int, int []);
int searchArray (int, int []);
int printArray (int, int []);

int main(){
 const int MAX = 25;
 int iArray[MAX]={0};
 int count;

 printf("Initializing lucky numbers...\n");
 fillArray(MAX,iArray);
 searchArray(MAX,iArray);

 getch();
 return 0;   
}

//Function Definitions

//Fill Array Function
int fillArray(int max, int Array[]){
int number;
int i=0;
int uniqueFlag;
srand(time(NULL));

while(i<max){
     number = (rand() % 101);
     if(checkArray(max, number, Array)==0){ //passes to another function to check for uniqueness
          Array[i]=number;
          ++i;
     }//end if
}//end while
return *Array;
}//end function

//Check Array Function
int checkArray(int max, int number, int Array[]){
int i;
int uniqueFlag;
for(i=0;i<=max;i++){
     if(Array[i]==number){  //determines if random number has already been used in array
          uniqueFlag = 1;
          return uniqueFlag;
     }//end if
     else{
          uniqueFlag = 0;
     }//end else
}//end for
     return uniqueFlag;
}//end function

//Search Array Function
int searchArray(int max, int Array[]){
int i;
int x=0;
int guessCounter=0;

while(x !=1 && guessCounter<3){

       scanf("%d",&iGuess);
       for(i=0;i<max;i++){

第一眼看不searchArray出来有没有问题，应该简化一下。我建议将整个uniqueFlag部分移出它自己的功能，doesArrayContain也许？
