并排打印两个二维数组

Question

我刚开始用 C 编写一个单元，我的第一个任务是制作经典战舰游戏的简单控制台版本。

其中的一部分——也是我目前遇到麻烦的部分——是在每个回合向玩家显示信息。

这就是我们被要求的显示效果：

并且，经过最少的大惊小怪，我的看起来像这样：

（我的 Player 网格目前是空的，因为它的二维数组是空的，但如果我使用一个包含一些东西的数组，就没问题。）

我的头文件：

/* Header files. */
#include <stdio.h>
#include <stdlib.h>

#define UNKNOWN ' '

#define SIZE 10

/* Function prototypes. */
void init(char playerHidden[SIZE][SIZE], char playerReveal[SIZE][SIZE],
      char computHidden[SIZE][SIZE], char computReveal[SIZE][SIZE]);
void displayKnownInfo(char playerReveal[SIZE][SIZE],
                  char playerHidden[SIZE][SIZE],
                  char computReveal[SIZE][SIZE]);

我的 C 源文件：

#include "bship.h"

int main(void)
{
   /* Stores player ship position information secret to opponent. */
   char playerHidden[SIZE][SIZE];
   /* Stores player ship position information known to opponent. */
   char playerReveal[SIZE][SIZE];
   /* Stores computer ship position information secret to opponent. */
   char computHidden[SIZE][SIZE];
   /* Stores computer ship position information known to opponent. */
   char computReveal[SIZE][SIZE];

   init(playerHidden, playerReveal,
        computHidden, computReveal);


   displayKnownInfo(playerReveal, playerHidden, computReveal);

   return EXIT_SUCCESS;
}


/****************************************************************************
* Function init() initialises every cell in the four grids to a safe default
* value. The UNKNOWN constant is used for the initialisation value.
****************************************************************************/
void init(char playerHidden[SIZE][SIZE], char playerReveal[SIZE][SIZE],
          char computHidden[SIZE][SIZE], char computReveal[SIZE][SIZE])
{
   /*Variables i and j for each dimension of the Arrays*/
   int x,y;

   /*For each increment BETWEEN 0 and 'SIZE', firstly for i;*/
   for(y=0; y<SIZE; y++)
   {
      /*And then for j;*/
      for(x=0; x<SIZE; x++)
      {
         /*Populate that cell with the constant UNKNOWN*/
         playerHidden[x][y]=UNKNOWN;

         playerReveal[x][y]=UNKNOWN;

         computHidden[x][y]=UNKNOWN;

         computReveal[x][y]=UNKNOWN;

      }

   }

}

void displayKnownInfo(char playerReveal[SIZE][SIZE],
                      char playerHidden[SIZE][SIZE],

{
   /*Ints for stepping through the arrays*/
   int i,j;

   /*Printing first few lines.*/

   printf("   +-+-+-+-+-+-+-+-+-+-+ |   +-+-+-+-+-+-+-+-+-+-+\n");

   for(i=0; i<SIZE; i++)
   {
      for(j=0; j<SIZE; j++)
      {
         /*Print the char at [i][j] with a '|' afterwards.*/
         printf("%c|",playerReveal[i][j]);
      }

      /*After reaching column '0' on the display, increment the row identifier*/
      row++;

      /*And print the 'spacer' row.*/
      printf("\n   +-+-+-+-+-+-+-+-+-+-+ |   +-+-+-+-+-+-+-+-+-+-+");

      /*If the current row identifier is less than 'k', we want to print it*/
      if(row<'k')
      {
         printf("\n %c |",row);
      }
      else
      {
         printf("\n");
      }

      /*And continue until the array has been printed in full.*/
   }

}

}

最终，PlayerHidden 数组将覆盖在 PlayerReveal 数组上，当玩家的船被击沉且其身份 'revealed' 时，但现在我只想让电脑显示器的一半工作。

Answer 1

只需在打印内容的第二个循环之后将其添加到您的代码中即可：

printf("   %c |", row);

for(j=0; j<SIZE; j++)
{
   /*Print the char at [i][j] with a '|' afterwards.*/
   printf("%c|",computReveal[i][j]);
}

因此您的代码如下所示：

//...
/*Loop through the arrays*/
for(i=0; i<SIZE; i++)
{
   for(j=0; j<SIZE; j++)
   {
      /*Print the char at [i][j] with a '|' afterwards.*/
      printf("%c|",playerReveal[i][j]);
   }
   printf("   %c |", row);
   for(j=0; j<SIZE; j++)
   {
      /*Print the char at [i][j] with a '|' afterwards.*/
      printf("%c|",computReveal[i][j]);
   }
   //...

Answer 2

您的问题是您只打印了播放器部分。看一下代码：

   for(i=0; i<SIZE; i++)
   {
      for(j=0; j<SIZE; j++)
      {
         /*Print the char at [i][j] with a '|' afterwards.*/
         printf("%c|",playerReveal[i][j]);
      }

      // ...
    }

您需要有另一个循环来打印 computerReveal 数组

   for(i=0; i<SIZE; i++)
   {
      for(j=0; j<SIZE; j++)
      {
         /*Print the char at [i][j] with a '|' afterwards.*/
         printf("%c|",playerReveal[i][j]);
      }

      for(j=0; j<SIZE; j++)
      {
         /*Print the char at [i][j] with a '|' afterwards.*/
         printf("%c|",computReveal[i][j]);
      }

      // ...
    }

应该可以了。您正在打印全宽行分隔符，而不是创建单元格分隔符的数组部分
