FILE HANDLING PROGRAMS

Description:

Here some tasks are performed using file handling concept.

CODE1:


#include<conio.h>
#include<fstream>
using namespace std;
int main()
{
ofstream outfile("TEST.TXT");
outfile<<"Ifear the ancient thee,ancient Mariner!\n";
outfile<<"I fear the skinny hand\n";
    outfile<<"And thou art long, and lank, and brown\n;
    outfile<<"As is the ribbed sea sand.\n";
getche();
}

CODE2:


#include<fstream>
#include<conio.h>
#include<iostream>
#include<string>
using namespace std;
int main()
{
string str="Time is a great teacher, but unfortunately"
"it kills all its pupils. Berlioz";
ofstream outfile("TEST.TXT");
for(intj=0;j<str.size();j++)
outfile.put(str[j]);
cout<<"File written\n"
getche();
}

CODE3:

#include<fstream>

#include<conio.h>

#include<iostream>

using namespace std;

int main()

{

ifstream infile("TEST.TXT");

cout<<infile.rdbuf();

cout<<endl;

getche();

}

CODE4:

#include<fstream>

#include<conio.h>

#include<iostream>

using namespace std;

class person

{

protected:

char name [80];

short age;

public:

void getData()

{

cout<<"Enter name : "cin>>name;

cout<<"Enter age: "cin>>age;

}

};

int main()

{

person pers;

pers.getData();

ofstream outfile("PERSON.DAT", ios::binary);

outfile.write(reinterpert_cast<char*>(&pers),sizeof(pers));

getche();

}

CODE5:

#include<fstream>

#include<conio.h>

#include<iostream>

class person

{

protected:

char name[80];

int age;

public:

void getdata()

{

cout "\nEnter name:";cin>>name;

cout<<"Enter age: ";cin >>age;

}

void showdata()

{

cout<<"\n Name: "<<name;

cout<<"\n Age: "<<age;

}

};

int main()

{

char ch;

person pers;

fstream file;

file.open("GROUP.DAT"), ios::app|ios::out|

ios::in|ios::binary);

do

{

cout<<"\nEnter person's data:";

pers.getdata();

file.write(reinterpret_cast<char*>(&pers),

sizeof(pers));

cout <<"enter another person(y/n)?"

cin>>ch;

}
