C++ – Creating and writing to a file.
In C++ we have the following classes to perform output and input operations of characters from/to files:
ofstream: class to write on files
ifstream: class to read from files
fstream: class to both read and write from/to files.
So in order to create a file and write to it we will use ofstream class.
Let’s say we want to create a file called codebind.txt and write something in it.
// Creating and writing to a file - C++
#include <iostream>
#include <fstream>
using namespace std;
int main () {
ofstream file;
file.open ("codebind.txt");
file << "Please writr this text to a file.\n this text is written using C++\n";
file.close();
return 0;
}
Output:
[file codebind.txt] Please writr this text to a file. this text is written using C++
where are the file saved?
#include
#include
using namespace std;
int main()
{
ofstream fs ; //name decleartion
char c [500]; //variable declearation to store the writen data
fs.open(“D:\project\file\test.txt”); //location fo file is in D drive
cout<<"Enter textn" ; //asking the user to input the text
cin>> c; //storing the content written by the user.
fs << c ; //file system writing the information in the text file
fs.close(); // file closure
return 0;
}
Since i am Learning, so far what i have understood i have tried.
