read and write python open file code example
Example 1: javascript write to file and download
function download(filename, text) {
var element = document.createElement('a');
element.setAttribute('href', 'data:text/plain;charset=utf-8,' + encodeURIComponent(text));
element.setAttribute('download', filename);
element.style.display = 'none';
document.body.appendChild(element);
element.click();
document.body.removeChild(element);
}
// Start file download.
download("hello.txt","This is the content of my file :)");
Example 2: how to read and write in a file c++
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;
