C++ question

Why do I get an infinite loop for the switch? And how do I save to a sub folder like: \saves\my_file.txt


CODE:
// Test-3.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <string>
using namespace std;

//functions
int write_file()
{
string text;
string file_name;
string ffile_name;

cout<<"Please write your text: ";
getline(cin,text);
getline(cin,text);
cout<<"\nEnd Text\n\nThank you.\n\nPlease enter your file name: ";
getline(cin,file_name);
ffile_name.append(file_name);
ffile_name.append(".txt");
cout<<"\nEnd File Name\n\nThank you.\n\nWriting "<<text<<" to "<<ffile_name<<"";

ofstream myfile;
myfile.open (ffile_name);
myfile << text;
myfile.close();
cout<<"\n\nEnd";
return 0;
}

int read_file()
{
string file_name;
string text;

cout<<"\nPlease enter the file name you wish to read: ";
getline(cin,file_name);
getline(cin,file_name);
file_name.append(".txt");

ifstream myfile (file_name);
if (myfile.is_open())
{
cout<<"\n\nData in "<<file_name<<":\n";
while ( myfile.good() )
{
getline (myfile,text);
cout << text << endl;
}
myfile.close();
}
cout<<"\n\nEnd";
return 0;
}

//int vars
int choice;

//main
int main()
{
while(0==0)
{
cout<<"\nEnter the number of your choice from the list below.";
cout<<"\n1. Read File";
cout<<"\n2. Write File";
cout<<"\n";
cin>>choice;
if(isdigit(choice)==0)
{
switch(choice)
{
case 1:
read_file();
break;
case 2:
write_file();
break;
}
}
else
{
cout<<"\nError";
}
}
}


Thank you.

 

by while function you will get infinite loop and for up site you declare file extension so your file would be save when program will execute.

 

What do you mean for up site declare function? COuld you give me an example?

 

For learning C++, what software should I install in my computer?

 

c++ .

 

Please use a better translator that outputs standard English. What you have said here looks like monkeys dancing on your keyboard.

 

I know. Could someone explain it to me in proper english. Thank you.
