5) Write a C++ Program that writing the data to a text file and then reading the data from same file.

 source file name: File4.cpp

#include <fstream.h>

#include <iostream.h>

#include<conio.h>

int main ()

 {

   char str[75];

   ofstream fout;

   fout.open("testout.txt");

   clrscr();

   cout <<"Writing to a text file:" << endl;

   cout << "Please Enter your name: ";

   cin.getline(str, 100);

   fout << str << endl;

   cout << "Please Enter your age: ";

   cin >> str;

   cin.ignore();

   fout << str << endl;

   fout.close();

   ifstream fin;

   const int N=80;

   char line[N];

   fin.open("testout.txt");

   cout << "Reading from a text file:" << endl;

   while (fin)

   {

   fin.getline (line,N);

      cout << line << endl;

   }

   fin.close();

   getch();

   return 0;

}
