Thread: replace character while writing into a file

Allocating "from the back" of MMU-size pages is a good idea.

Anyways, I spent a few moments hacking up a C++ variant:

Code:

#include <iostream>
#include <fstream>
#include <string>

using namespace std;

int main(int argc, char **argv)
{
    ifstream fin;
    ofstream fout;
    if (argc > 1)
	fin.open(*++argv);
    if (argc > 2)
	fout.open(*++argv);

   if (fin && fout) 
   {
       do { 
	   char buffer[1000]; 
	   char *p;
	   char *s;
	   while(fin.getline(s = buffer, sizeof(buffer)-1, '\n'))
	   {
	       p = s;
	       while(p = strchr(s, 'w'))
	       {
		   s = p+1;
		   if ((p - buffer > 2) && 
		       (p[-1] == 'o') && (p[-2] == 'l') && 
		       (p[-3] == 'f') &&  (p[1] == 'o') && 
		       (p[2] == 'r') && (p[1] = 'e'));
               }
	       fout << buffer << endl;
	   }
       } while(fin);
   }
   else
   {
       cout << "Could not open input files" << endl;
       return 1;
   }
   return 0;
}
