Few things about arrays and fopen

[schnellboot]

First
how can I make an array[144] into this 12x12 string?
123456789012
123456789012
123456789012
123456789012
123456789012
123456789012
123456789012
123456789012
123456789012
123456789012
123456789012
123456789012

And how can I save this string to a read-able txt just like that?
I only have this

Code: Select all

FILE *file;
file = fopen ("test.txt", "w");
fprintf (file, "something");
fclose (file);


"something" has to be changed if the numbers above ..

Thanks in advance ..

Here is what you need guy. Just for learn only!

Code: Select all

#include "stdafx.h"
#include <stdio.h>


int _tmain(int argc, _TCHAR* argv[])
{

   char cArray[144];
   for (int j= 0; j < 12; j++)
   {
      for (int i= 0; i < 12; i++)
      {
         if (i + 1 >= 10)
         {
            cArray[i + j*12]= i + 1 - 10 + '0';
         }
         else
         {
            cArray[i + j*12]= i + 1 + '0';
         }

      }
   }
   FILE * pFile;
   pFile = fopen ("myfile.txt","w");
   char c;

   if (pFile!=NULL)
   {
      for (int j= 0; j < 12; j++)
      {
         for (int i= 0; i < 12; i++)
         {
            
            c = cArray[i + j*12];
            fputc ( (int) c , pFile );
         }
         fputs  ( "\n" , pFile );
      }
      
      fclose (pFile);
   }

   return 0;
}
