Answer 1

#include <iostream>
#include <fstream>
#include <string>
#include <cstdlib>
#include <ctime>

using namespace std;

int main() {
    srand(time(NULL));
    string fileName;
    cout << "Enter file name: ";
    cin >> fileName;
    ofstream out(fileName.c_str());
    for (int i = 0; i < 1000; ++i) {
        out << (1 + rand() % 1000) << endl;
    }
    cout << "Random numbers are written to " << fileName << endl;
    out.close();
    return 0;
}

Enter file name: numbers.txt Random numbers are written to numbers.txt
