Thread: Diff compiler == diff program????

This is REALLY starting to bug me. Really.

The folling code, under:

gpp, compiles and removes the tenth integer form a space delimited list of integers in file.txt

Dev-C++, does nothing at all

Turbo, deletes the contents of the file and replaces it with meaningless data.

WHYYYY?????

Is this not ANSI compilant? Anyone????

Code:

/*
   Kth Integer remover

This program reads all integers up to and including the Kth, but no more, from a text file called file.txt. It then eliminates the Kth integer. No other numbers are read or otherwise modified.

Prerequisite: A space delimited integer file called file.txt exists in the cwd.

Note: It may be helpful to, when making the file, make one line of numbers, then another identical line below it. This allows you to better see the removal of the number.

#include <iostream.h>
#include <fstream.h>
#include <math.h>


//This integer is to be removed from the file, bye bye!
#define Kth_integer 10

   int lenof(int);

   int main () {
      bool stop = false;
      int b = 0;
      int inums[Kth_integer];
      ifstream ifile("file.txt", ios::in);
      for (int b = 1; b <= Kth_integer; ++b)  {
         ifile >> inums[b];
      }
      ifile.close();
      ofstream ofile("file.txt", ios::in);
      for (int b = 1; b < Kth_integer; ++b)  {
         ofile << inums[b];
         ofile << ' ';
      }
      for (int x = 0; x < lenof(inums[Kth_integer]); ++x) {
         ofile << ' ';
      }
      ofile.close();
      return 0;
   }

   int lenof (int a) {
      int b = 1;
      while (a/pow(10, b) >= 1) {
