How to solve

Learner Objectives

By completing this assignment, students will:

Understand how to perform file input$/$output operations in C$++$ using ifstream and

ofstream.

Learn how to read from and write to files.

Practice error checking and handling for file operations.

Reinforce the use of loops and conditionals in C$++.$

Prerequisites

Before starting this assignment, students should have:

A basic understanding of C$++$ syntax and program structure.

Familiarity with variables, data types, and basic console input$/$output operations.

Knowledge of control flow statements, including loops $($for$,$ while$)$ and conditionals $($if$,$

else$).$

An introduction to file handling using file streams in C$++.$

Overview and Requirements

You are to write a $C++$ program that copies the contents of one text file to another. In this

assignment, you are tasked with writing a C$++$ program that copies the contents of one text file

to another. The program will begin by prompting the user to enter the name of the source file$-$

the file to be copied. It will then attempt to open this source file for reading. Once the source file

is successfully opened, the program will prompt the user to enter the name of the destination

file $-$ the file where the content will be copied to$.$ The program then reads the contents of the

source file and writes them to the destination file, ensuring that the contents are copied exactly as

they appear in the source file. Finally, the program will inform the user that the copying has been

completed successfully.

Program Details

Your program should perform the following steps:

User Input for Source File

Prompt the user with: Enter the source filename:

Read the source filename from the user input.

Open Source File

Attempt to open the source file using an ifstream.

If the file cannot be opened, display an error message:

Error: Could not open source file $\text{'}$

File has been copied successfully.

Example Run of the Program

Note: $\_\_$ indicates input typed by the user.

Successful Copy

Enter the source filename: source.txt

Enter the destination filename: destination.txt

File has been copied successfully.

Source File Does Not Exist

Enter the source filename: nonexistent.txt

Error: Could not open source file 'nonexistent.txt$\text{'}.$

Program will exit.

Bonus $(10$ points$)$

Enhance your program by adding a menu that allows the user to select the following options:

Open a source filename to copy.

Open$/$Create a destination filename.

Verify source and destination files content.

The menu should loop, allowing the user to perform multiple operations until they choose to exit.

Bonus Task Details

Implement a menu system that allows the user to perform the following actions:

Open a source filename to copy

Prompt the user for the source filename.

Attempt to open the source file and handle any errors.

Open$/$Create a destination filename

Prompt the user for the destination filename.

Attempt to open $($or create$)$ the destination file.

Verify source and destination files content

Display the contents of both the source and destination files side by side for

comparison.

Handle the case where files may not have been specified or opened yet.

Exit

Allow the user to exit the program.

Menu Implementation Guidelines:

The menu should loop until the user chooses to exit.

Validate user input for menu choices.

Ensure that appropriate actions are taken based on the user's selection.

Provide clear instructions and feedback to the user.

Note: The program should handle all errors gracefully, providing clear error messages to the user

and exiting the program if necessary.
