Hi everyone I am trying to create a file that converts text files from
unix to windows and windows to unix
I understand the general concept of it as
unix uses line feed LF
Windows uses CRLF carrige return and feed line
my program will prompt the user to enter a file to open and then
prompts for a destination file to save the new formatted file.
I am having few problems that i have been trying to solve for few
hours
here is the code I created
#include <iostream>
#include <fstream>
using namespace std;
const string unix = "/uw";
const string windows = "/wu";
const string help = "/?";
int uw();
int wu();
int helpfile();
int main()
{
string option;
cout << "\n";
cout << "************** ********** Menu *************** ******\n";
cout << "\n";
cout << " Please choose from the following list\n";
cout << "\n";
cout << " * type /uw to convert a file from Unix to Windows\n";
cout << " * type /wu to convert a file from Windows to Unix\n";
cout << " * type Help to Display the help file\n";
getline(cin,opt ion);
while((option != unix) && (option!= windows) && (option != help) ){
cout << " that's not a valid option! Try again\n";
getline(cin,opt ion);
}
if (option == unix){
uw();
}else if(option == windows){
wu();
}else if(option == help){
helpfile();
}
return 0;
}
int uw(){
char FileName[20];
char Destination[20];
cout << "please enter the name of the source file: \n";
cin >> FileName;
ifstream in(FileName,ios ::binary | ios:: in);
if(!in){
cout << "Error opening source\n";
return 0;
}
cout << "please enter the name of the destination file: \n";
cin >> Destination;
while(FileName == Destination){
cout << "Source and Destination file names must be different please
try another:\n";
cin >> Destination;
}
ofstream out(Destination ,ios::binary | ios::out);
if(!out){
cout << "Error creating destination file \n";
return 0;
}
char c;
while(in.get(c) ){
out.put(c);
if(c == 13){
cout << "Carriage return, not a Unix text file please reconsider
option\n";
}
if(c == 10){
cout << "Line feed\n";
}
}
in.close();
out.close();
return 0;
}
int wu(){
char FileName[20];
char Destination[20];
cout << "please enter the name of the source file (i.e.) file1.txt
\n";
cin >> FileName;
ifstream in(FileName ,ios::binary | ios:: in);
if(!in){
cout << "Error opening source\n";
return 1;
}
cout << "please enter the name of the destination file: \n";
cin >> Destination;
while(FileName == Destination){
cout << "Source and Destination file names must be different please
try another:\n";
cin >> Destination;
}
ofstream out(Destination ,ios::binary | ios::out);
if(!out){
cout << "Error creating destination file \n";
return 0;
}
char c;
while(in.get(c) ){
out.put(c);
if(c == 13){
cout << "Carriage return\n";
}
if(c == 10){
cout << "Line feed\n";
}
}
in.close();
out.close();
return 0;
}
int helpfile(){
//system("pause") ;
cout << "\n\nHere is c:\\help.txt \n\n";
ifstream inf("c:\\help.t xt",ios::in);
if(!inf){
cout << "Error reading file\n";
return 1;
}
string theLine = "";
while(getline(i nf,theLine)){
cout << theLine << endl;
}
inf.close();
return 0;
}
