flat file java read write code example

Example 1: how to read and write in a file c++

#include <iostream>
#include <fstream>
using namespace std;

ifstream file_variable; //ifstream is for input from plain text files
file_variable.open("input.txt"); //open input.txt

file_variable.close(); //close the file stream
/*
Manually closing a stream is only necessary
if you want to re-use the same stream variable for a different
file, or want to switch from input to output on the same file.
*/
_____________________________________________________
//You can also use cin if you have tables like so:
while (cin >> name >> value)// you can also use the file stream instead of this
{
 cout << name << value << endl;
}
_____________________________________________________
//ifstream file_variable; //ifstream is for input from plain text files
ofstream out_file;
out_file.open("output.txt");

out_file << "Write this scentence in the file" << endl;

Example 2: how to write and read a text file in jdiscord.js

npm install fs --save -g
//You can read from the file like this:
// File system stuff.
var fs = require("fs");

// Get the text file and load it into a variable.
var file = fs.readFileSync("path/to/my/text/file.txt", "utf8");

//And you can write to the file like this:
// Write the file
fs.writeFile("path/to/my/text/file.txt", myVariable, function (err) {

    // Checks if there is an error
    if (err) return console.log(err);
  });
