数组内

Question

我试图在数组的每列中的某些范围之间随机获取一个随机数，以便模仿宾果卡。

第一列应包含1到10的数字，第二列应包含11到20的数字，第三列应包含21到30，依此类推，直到最后一列，其中包含从81到90的数字。

以下是我根据以下答案修改的代码：

 for (row = 0; row<3; row++)
            {
                for (col = 0; col<9; col++)
                {
                    if (col == 0)
                    {
                        bingoCard[row][col] = (rand() % 10) + 1 + col * 10;

                    }//end of 1st col

                    else if (col == 1)
                    {
                        bingoCard[row][col] = (rand() % 10) + 1 + col * 10;

                    }//end of 2nd col

                    else if (col == 2)
                    {
                        bingoCard[row][col] = (rand() % 10) + 1 + col * 10;

                    }//end of 3rd col

                    else if (col == 3)
                    {
                        bingoCard[row][col] = (rand() % 10) + 1 + col * 10;

                    }//end of 4th col

                    else if (col == 4)
                    {
                        bingoCard[row][col] = (rand() % 10) + 1 + col * 10;

                    }//end of 5th col

                    else if (col == 5)
                    {
                        bingoCard[row][col] = (rand() % 10) + 1 + col * 10;

                    }//end of 6th col

                    else if (col == 6)
                    {
                        bingoCard[row][col] = (rand() % 10) + 1 + col * 10;

                    }//end of 7th col

                    else if (col == 7)
                    {
                        bingoCard[row][col] = (rand() % 10) + 1 + col * 10;

                    }//end of 8th col

                    else if (col == 8)
                    {   
                        bingoCard[row][col] = (rand() % 10) + 1 + col * 10;

                    }//end of 9th col

                }// end col for

现在代码输出以下内容：

***New Game***

2       18      25      5       16      26      8       17      22
5       16      26      8       17      22      35      43      54
8       17      22      35      43      54      63      73      82

一旦超过第3列，它仍然有效吗？从那里每列中有一个值是对的吗？

Answer 1

这是一种执行非常简单任务的复杂方法

获取范围内的随机数很简单(rand() % range_size) + range_start。

下面

for (col = 0; col < 9; col++)
{
    for (row = 0; row < 3; row++)
    {
        bingoCard[row][col] = rand() % 10 + (col * 10 + 1);
    }
}

Answer 2

您实际上只生成0-9之间的随机数，并在其中添加＆＃34; base＆＃34;每列。这是一个完整的例子;

#include <stddef.h>

#define ROWS 3
#define COLS 9
int bingoCard[ROWS][COLS];

main()
{
  int col, row;

  srand(time(NULL));

  for (row = 0; row<ROWS; row++)
  {
      for (col = 0; col<COLS; col++)
      {
          bingoCard[row][col] = (rand() % 10) + 1 + col*10;
      }
  }

  for (row = 0; row<ROWS; row++)
  {
      for (col = 0; col<COLS; col++)
      {
          printf("%d\t", bingoCard[row][col]);          
      }
      /* put a newline */
      puts("");      
  }
}
