Question

我正在编写Conway的生命游戏。我的任务是从file.txt读取字符串数组。然后使用此数组作为游戏的输入数组。我写了一个关于它的代码。但它充满了错误。我不知道这样做的正确方法是什么。

#include <iostream>
#include <string>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <fstream>

    using namespace std;
namespace gamearray {

    ifstream file_("file.txt");
    if(file.is_open())
    {

        for(int i = 0; i < 10; ++i)
        {
        for(int i = 0; i < 10; i++)

            file >> array1[j][i];
        }
    }
return 0; 
}

void copy(int array1[10][10], int array2[10][10])
{
  for(int j = 0; j < 10; j++)
  {
        for(int i = 0; i < 10; i++)
            array2[j][i] = array1[j][i];
    }
}


void life(int array[10][10], char choice)
{

  int temp[10][10];
  copy(array, temp);
    for(int j = 0; j < 10; j++)
    {
        for(int i = 0; i < 10; i++)

            if(choice == 'm')
            {

                int count = 0;
                count = array[j-1][i] +

            }


        }
    }

  copy(temp, array);
}

而不是以前我写的新。它工作了

Answer 2

aftert主要缺少{ 在第一个和第二个循环中，你有两次循环

为什么需要复制？

您可以使用此函数fscanf（）来读取您的文件

e.g。

File= fopen(FileName, "r");
             if( File == NULL ){
            printf("Impossible to open  file %s ! \n",FileName);
        }

if( File != NULL)
{
   char text[255];
   while(!feof(File))
   {
      fscanf(File,"%s\n",&text);
      ....
   }
}

从file.txt读取字符串数组并使用它来播放Conway的生命游戏
