Read / Write files

This tutorial will demonstrate how to read in a file and also output the details to another file. The headers
fstream and iostream
basically include details on File-streaming (fstream) and In-Output-Streaming (iostream).

I have attached the code within a zip file with the required input file as well.

The namespace denotes which area are you in, for example : maths:algebra would mean you are doing maths and with the topic of Algebra, within the c/c++ example std::ifstream means that the namespace is std and the function/variable is ifstream.

NOTE: the { } are the begin and end of a code structure, e.g. While begin; do something; end;

#include 

#include 

#include 

using namespace std;// use the namespace (e.g. instead of putting std::ifstream you just need to put fstream.)
int main(void)

{

       char InStr[100];

       ifstream InFile("countrys.txt",ios::in);// infile

       ofstream OutFile("outcountrys.txt", ios::out);// outfile
       while (InFile.getline(InStr,100))// while reading each line within the file

       {

              printf("%s\n", InStr);// output the read line to the console

              OutFile <<
