C++：ifstream作爲參數

我試圖做一個程序，它能夠同時創建一個.txt文件並從中讀取它來創建針對Linux的tic-tac-toe的輸出。但是，我的一個函數並沒有初始化它的第一個參數，即來自所討論文件的輸入流，以便創建所需的輸出。C++：ifstream作爲參數

的函數原型：

void loadSquaresFromStream( ifstream inStream, char statusSquare[], int currGame, int 
row, int column, int mark, int player, int games_Left); 

// This function reads from the file 'games.txt' and uses it to update the array 
// used to output each game.

功能頭部和身體：

void loadSquaresFromStream( ifstream inStream, char statusSquare[], int currGame, int 
row, int column, int mark, int player, int games_Left) { 
    while (currGame == 1) { 
    inStream >> row >> column; 
    if (row == 1 && column == 1 && statusSquare[1] == ' ') { 
     statusSquare[1] = mark; 
     player++; 
    } 
    else if (row == 1 && column == 2 && statusSquare[2] == ' ') { 
     statusSquare[2] = mark; 
     player++; 
    } 
    else if (row == 1 && column == 3 && statusSquare[3] == ' ') { 
     statusSquare[3] = mark; 
     player++; 

.... 
.... 
    else if (row == 0 && column == 0) { 
    currGame = 0; 
    } 
    else { 
     currGame = 0; 
     games_Left = 0; 
    } 
    } 
}

，並在主功能區：

int main() { 
.... 
.... 
else if (option == '2') { //line 189 
    cout << " Checking for file 'games.txt' in current directory... " << endl; 
    inStream.open ("games.txt"); 
    if (inStream.fail()) { 
    cout << " ERROR: File 'games.txt' was not found. Please re-execute this program and play a game to create the file before using this feature. " << endl; 
    exit(1); 
    } 
    else { 
     cout << " File 'games.txt' found. Displaying output now. " << endl << endl; 
    } 
    system("cls"); 
    while (games_Left == 1) { 
     cout << "Board Positions for Game " << games << ": " << endl; 
     loadSquaresFromStream(inStream, statusSquare, currGame, row, column, mark, player, games_Left); //line 202 
.... 
.... 
}

這是錯誤的語法我同時嘗試從cygwin和code :: blocks進行編譯。

任何人都可以弄清楚程序出了什麼問題嗎？

編輯：參照改變ifstream的一個電話後，我得到這個，當我試圖編譯：

/tmp/ccM1q9XN.o:jebecker_assignment01.cpp:(.text+0x416): undefined reference to `displayActiveBoard()' 
/tmp/ccM1q9XN.o:jebecker_assignment01.cpp:(.text+0xaf5): undefined reference to `checkActiveGameStatus()'

collect2: error: ld returned 1 exit status

這是關係到我如何寫我的其他功能，還是因爲「games.txt '還不存在？
