從file.txt讀取字符串數組，並用它來玩康威的生活遊戲

Question

我正在編寫一個康威的生命遊戲。我的任務是從file.txt讀取字符串數組。然後使用這個數組作爲輸入遊戲陣列。我寫了一個關於它的代碼。但它充滿了錯誤。我不知道這樣做的正確方法是什麼。

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

    using namespace std; 
namespace gamearray { 
    int main() 


    ifstream file_("file.txt"); 
    if(file.is_open()) 
    { 
     string myArray[10]; 

     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] + 
        array[j-1][i-1] + 
        array[j][i-1] + 
        array[j+1][i-1] + 
        array[j+1][i] + 
        array[j+1][i+1] + 
        array[j][i+1] + 
        array[j-1][i+1]; 

     if(count < 2 || count > 3) 
        temp[j][i] = 0; 

     if(count == 2) 
        temp[j][i] = array[j][i]; 

     if(count == 3) 
        temp[j][i] = 1; 
      } 


     } 
    } 

    copy(temp, array); 
} 


bool compare(int array1[10][10], int array2[10][10]) 
{ 
    int count = 0; 
    for(int j = 0; j < 10; j++) 
    { 
     for(int i = 0; i < 10; i++) 
     { 
      if(array1[j][i]==array2[j][i]) 
       count++; 
     } 
    } 

    if(count == 10*10) 
     return true; 
    else 
     return false; 
} 


void print(int array[10][10]) 
{ 
    for(int j = 0; j < 10; j++) 
    { 
     for(int i = 0; i < 10; i++) 
     { 
      if(array[j][i] == 1) 
       cout << '*'; 
      else 
       cout << ' '; 
     } 
     cout << endl; 
    } 
} 


int main() 
{gamearray::main(); 

int gen0[10][10]; 
int todo[10][10]; 
int backup[10][10]; 
char neighborhood; 
char again; 
char cont; 
bool comparison; 


{do 
    { 

    do 
     { 
    cout << "Which neighborhood would you like to use (m): "; 
      cin >> neighborhood; 
     }while(neighborhood != 'm'); 

    system("CLS"); 
    int i = 0; 

    do 
     { 

      srand(time(NULL)); 

      for(int j = 0; j < 10; j++) 
      { 
       for (int i = 0; i < 10; i++) 
        gen0[j][i] = rand() % 2; 
      } 



    if(i == 0) 
       copy(gen0, todo); 
      copy(todo, backup); 
      print(todo); 
      life(todo, neighborhood); 
      i++; 


    system("sleep .5"); 

    if(i % 10 == 1 && i != 1) 
    { 
     cout << endl; 

     do

     cout << "Would you like to continue this simulation? (y/n): ";

    }while(again != 'y' && again != 'n'); 
    }while(again == 'y'); 

    return 0; 
    } 
} 

Answer 1

aftert主要在第一和第二環缺少{ 你有我兩次循環

爲什麼你需要複製？

您可以使用此功能的fscanf（）讀取文件

例如而不是以前的

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); 
     .... 
    } 
}

我寫了新的。它的工作
