    const readline = require('readline');
    const fs = require('fs');

    const rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout
    });

    // Prompt user for file names
    rl.question('Enter the name of the first file: ', (file1) => {
    rl.question('Enter the name of the second file: ', (file2) => {
    // Read content of file1
    fs.readFile(file1, 'utf8', (err, data) => {
    if (err) {
    console.error('Error reading file1:', err);
    rl.close();
    return;
    }

    // Append content of file1 to file2
    fs.appendFile(file2, data, (err) => {
    if (err) {
    console.error('Error appending to file2:', err);
    rl.close();
    return;
    }

    console.log(`Contents of ${file1} appended to ${file2} successfully!`);
    rl.close();
    });
    });
    });
    });
