File Handling using C++ Part-II | File Reading and Writing

 Problem Statement: Write a C++ program to create a file “mydata.txt”, accept the name and age of 10 persons from the console and add them to the file (each record must be on a new line). Read the contents of the file back in two variables (name and age) and display them on the console.

Use following ways to read & write data and identify the difference:

    1. Extraction & insertion operators

    2. get() & put() functions of stream classes

#include <iostream>

#include <fstream>

#include <string.h>

using namespace std;

int main()

{

    string name;

    int age;

    ofstream f1;

    f1.open("mydata.txt");

    cout<<"Enter the details below"<<endl;

    for(int i=0;i<10;i++){

        cout<<i+1<<".Name: ";

        cin>>name;

        cout<<"Age: ";

        cin>>age;

        cout<<endl;

        f1<<i+1<<".Name: "<<name<<endl;

        f1<<"Age: "<<age<<endl;

        f1<<endl;

    }

    f1.close();

   

    ifstream f2;

    string output;

    f2.open("mydata.txt");

    while(getline(f2, output)){

        cout<<output<<endl;

    }

    f2.close();

   

    return 0;
