SAMPLE PROGRAM:

// sample program to create a file with user input
// program will create a file containing 5 sets of entries of name and age

#include<iostream.h>
#include<assert.h>                            // needed to detect file errors
#include<fstream.h>                         // necessary for file I/O
#include "apstring.cpp"

int main(void)
{
     apstring name, dummy;
     int age;
     ofstream fout;             // declares stream variable called fout
     fout.open("name_age.dat", ios :: out);                // create file
     assert(! fout.fail( ));                                      // to detect any access errors

    for(int x = 1; x <= 5; x++)
   {
         cout << "Enter your name: ";                    // get name from user
         getline(cin, name);                                    // allowing for multiple word entry
         cout << "Enter your age: ";                       // get age from user
         cin >> age;
         getline(cin, dummy);                                  //flush the stream

         fout << name << endl;        //write name to file on its own line
         fout << age << endl;           // write age to the file
    }

    fout.close( );                            //close the file
    assert(! fout.fail( ));                // to detect any errors in closing

    return 0;
