Question

I’m at the time beginning the development of a simple hex editor(that only reads at the time). I want to substitute OA for "\n", I’m trying with this code:

#include <iostream>
#include <fstream>
#include <iomanip>
using namespace std;

int main() {
   ifstream infile;
   int crtchar = (int)infile.get();
   infile.open("test.txt", ifstream::in);
   while(infile.good())
   {
      if(crtchar != 0xA)
         cout << hex << setfill('0') << setw(2) << crtchar << ":";
      else
         cout << endl;
   }
   cout << "\n=====================================\n";
   infile.close();
   return 0;
}

It compiles without errors, but when I try to execute it, I just got nothing:

C:\Documents and Settings\Nathan Campos\Desktop>hex

=====================================

C:\Documents and Settings\Nathan Campos\Desktop>

This is happening just after I’ve added the feature to substitute OA for \n, because before it was working very nice. What is wrong?

Answer 1

You realize that you are only reading a character once, and before even opening the file, at that?
