C++ FILE function

[mitola]

I managed to actually create a file. but then i have problems beacuse i dont know hot to write something in it and read it. i like this function beacuse you can save your data in it.

so im asking you how to make program able to write and read and then also save it.

#include <stdio.h>
#include <stdlib.h>
 
int main()
{
   FILE * pFile;
   char buffer [100];
 
   pFile = fopen ("myfile.txt" , "wr");
   fputs ("fopen example",pFile);
   if (pFile == NULL) perror ("Error opening file");
   else
   {
     while ( ! feof (pFile) )
     {
       fgets (buffer , 100 , pFile);
       fputs (buffer , stdout);
     }
     fclose (pFile);
   }
   system("pause");
   return 0;
}

First, open the file for writing.
Then write the data.
Then close the file.
Then re-open the file fior reading
Then read the file.

Be sure when you open that you use the correct codes to start at the beginngin or end, etc.
