如何为扫雷 C++ 程序声明一个工作变量?

How do I declare a working variable for minesweeper C++ program?

我目前正在解决一个扫雷 C++ 程序,当程序完成时我无法收到正确的输出。我知道这是一个逻辑错误,很可能来自“currentCell”变量,但我不知道如何让它工作。我的输出结果是这样的:____________________________________________________________________________________________________ ----

#include <iostream>
#include <iomanip>
#include <time.h>

using namespace std;

// Global Constants
const int MAX_ROWS = 10;
const int MAX_COLUMNS = 10;
const int EMPTY_SQUARE_DIGIT = 0;
const char EMPTY_SQUARE_SYMBOL = '_'; 
const int BOMB_DIGIT = -1;
const char BOMB_SYMBOL = '#';
char currentCell = 0;

// Function Prototypes
void fillTheGameBoard(int board[MAX_ROWS][MAX_COLUMNS]);
void displayTheGameBoard(int board[MAX_ROWS][MAX_COLUMNS]);
void insertTheMineClues(int board[MAX_ROWS][MAX_COLUMNS]);
void incrementTheNeighborSquares(int board[MAX_ROWS][MAX_COLUMNS], int row, int column);


// ############################################
int main(void)
{
   int gameBoard[MAX_ROWS][MAX_COLUMNS];

   srand(time(NULL));
   fillTheGameBoard(gameBoard);
   insertTheMineClues(gameBoard);
   displayTheGameBoard(gameBoard);
   return 0;
} // End main


// ############################################
void fillTheGameBoard(int board[MAX_ROWS][MAX_COLUMNS])
{
   for (int row = 0; row < MAX_ROWS; row++)
   {
      if ( (row >= 0) && (row < MAX_ROWS) )
      {
         for (int column = 0; column < MAX_COLUMNS; column++)
         {
            if (rand() % (MAX_ROWS - 3) == 0)
            {
               currentCell = BOMB_DIGIT;
            }
            else
            {
               currentCell = EMPTY_SQUARE_DIGIT;
            }
         }
      }
   }

            else if (currentCell == EMPTY_SQUARE_DIGIT)
            {
               cout << EMPTY_SQUARE_SYMBOL;
            }
            else
            {
               cout << currentCell;
            }
         }
      }
   }

您将游戏板传递给这些函数中的每一个,但从未使用过参数

好的,你至少有两个问题。

最大的一个:

您正在设置变量 currentCell,但您的实际意思是设置 面板中的一个单元格

更改对此的所有分配和引用:

board[row][column]

第二题:

打印函数不打印换行符。只需将 cout << endl; 添加到嵌套 for 循环的末尾即可修复它。

第三题:

这实际上不是问题,但它让我的眼睛受伤;-)

您有:

   for (int row = 0; row < MAX_ROWS; row++)
   {
      if ( (row >= 0) && (row < MAX_ROWS) )
      {

嵌套 if 没有意义,因为它 总是 计算为 true
