MariettaO [177]

Answer:

The program in cpp for the given scenario is shown below.

#include <stdio.h>

#include <iostream>

#include <fstream>

using namespace std;

int main()

{

   //object created of file stream

   ofstream out;

   //file opened for writing

   out.open("numbers.txt");

   std::cout << "File opened." << std::endl;

   //inside for loop, random numbers written to numbers.txt using rand()

   for(int n=0; n<10; n++)

   {

       out<<rand()<<endl;

   }

   //file closed

   out.close();

   std::cout << "File closed." << std::endl;

   return 0;

}

out.open("numbers.txt");

out<<rand()<<endl;

6. Every execution of the for loop repeats steps 4 and 5.

7. When the loop ends, the file is closed using close() method with the object of ofstream.

out.close();

8. A message is displayed to the user that the file is closed.

9. The header file, fstream, is included to support file operations.

10. The extension of the file can be changed from .txt to any other type of file as per requirement.

11. The program can be tested for writing more numbers to the file.

12. The program can be tested for writing any type of numeric data to the file.

13. The program is written in cpp due to simplicity.

14. In other languages such as java or csharp, the code is written inside classes.

15. In cpp, all the code is written inside main() method.
