Question

I am not the best programmer with c++ but I am trying to learn. I am trying to take user input and write it into a text file (without overwriting the old one) but I can’t figure out where to plugin the variable (int). Here is my code so far…

int main()
{
   int i;
  cout << "Please enter something: ";
  cin >> i;

   FILE * pFile;
  pFile = fopen ("C:\\users\\grant\\desktop\\test.txt","a");
  if (pFile!=NULL)

    fputs ("C++ Rocks!",pFile);
    fclose (pFile);
  getch();
  return 0;
}

Also, if there is a more effecient way of doing this, please let me know! This is just what I was able to find on the internet that worked.

I think this would do:

{
  string i; // dont forget to #include <string>
  cout << "Please enter something: ";
  cin >> i;

  FILE * pFile;
  pFile = fopen ("C:\\users\\grant\\desktop\\test.txt","a");
  if (pFile!=NULL)
  {
     fputs("C++ Rocks!", pFile);
     fputs(i.c_str(), pFile);
  }

  fclose (pFile);
  getch();
  return 0;
}
