Reading from file.txt to array of strings and using it to play Conway's game of Life

I am coding a Conway's Game of Life.My task is reading from file.txt to array of strings.And then using this array as the input array of the game. I have written a code about it. But it is full of error. I don't know what is the correct way to do this.

#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): ";
cin >> cont;
}while(cont != 'y' && cont != 'n');
if(cont == 'n')
break;
}

comparison = compare(todo, backup);
if(comparison == false)
system("CLS");
if(comparison == true)
cout << endl;
}while(comparison == false);
do
{
cout << "Would you like to run another simulation? (y/n): ";
cin >> again;
}while(again != 'y' && again != 'n');
}while(again == 'y');

return 0;
}
}

Answer

aftert main you are missing { in first and second loop you have i loop twice

why do you need to copy ?

you can use this function fscanf() to read your file

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);
      ....
   }
}
