Create A Text File And Copy This Text To It

Create A Text File And Copy This Text To Itshall I Compare Thee To

1. Create a text file and copy this text to it: Shall I compare thee to a summer's day? Thou art more lovely and more temperate: Rough winds do shake the darling buds of May, And summer's lease hath all too short a date: Sometime too hot the eye of heaven shines, And often is his gold complexion dimm'd; And every fair from fair sometime declines, By chance, or nature's changing course, untrimm'd; But thy eternal summer shall not fade Nor lose possession of that fair thou ow'st; Nor shall Death brag thou wander'st in his shade, When in eternal lines to time thou grow'st; So long as men can breathe or eyes can see, So long lives this, and this gives life to thee.

2. Add the following code to your Main():

int main() {


std::ifstream in_file{"../poem.txt"};


std::ofstream out_file{"../poem_out.txt"};


if (!in_file) {


std::cerr 

return 1;


}


if (!out_file) {


std::cerr 

return 1;


}


std::string line{};


while (std::getline(in_file, line))


out_file 

std::cout 

in_file.close();


out_file.close();


return 0;


}

3. Analyze the code, fully understand it, and change the code to manipulate the file and add a line number to the beginning of each line. Your output should look like this:

1 Shall I compare thee to a summer's day?


2 Thou art more lovely and more temperate:


3 Rough winds do shake the darling buds of May,


4 And summer's lease hath all too short a date:


5 Sometime too hot the eye of heaven shines,


6 And often is his gold complexion dimm'd;


7 And every fair from fair sometime declines,


8 By chance, or nature's changing course, untrimm'd;


9 But thy eternal summer shall not fade


10 Nor lose possession of that fair thou ow'st;


11 Nor shall Death brag thou wander'st in his shade,


12 When in eternal lines to time thou grow'st;


13 So long as men can breathe or eyes can see,


14 So long lives this, and this gives life to thee.

4. Copy your code and paste it here (text input).

Paper For Above instruction

The task involves creating, copying, and manipulating text files in C++ programming language. Initially, the requirement is to create a text file containing William Shakespeare's Sonnet 18, "Shall I compare thee to a summer's day?" and then copy this content to a new file using C++ file stream operations. The subsequent step is to analyze the provided code, understand its functionality, and modify it so that each line of the text file is prefixed with its corresponding line number.

The initial step is straightforward—writing the poem into a text file named "poem.txt". The program reads this file and copies its content into another file, "poem_out.txt". This process leverages the ifstream and ofstream classes in C++ for input and output file handling, respectively. It includes error handling to ensure that files open successfully before proceeding with the copying process. The program reads each line sequentially using std::getline and writes it to the output file, demonstrating basic file manipulation operations in C++.

The core challenge lies in enhancing the code’s functionality to prepend line numbers to each line during the copy process. This involves integrating a counter variable that increments with each line read, and utilizing the output stream to write the line number before the line content. The modified code should preserve the existing input/output handling structure but augment the output to include these line numbers, producing an output similar to the specified format.

Implementing this feature requires understanding C++ string streams, formatting options, and ensuring that the line numbering aligns correctly with the content. Additionally, it emphasizes good programming practice by maintaining proper resource management—closing file streams after operations complete. This task not only reinforces foundational C++ file I/O concepts but also demonstrates how to augment simple file copying with additional formatting, a common requirement in text processing applications.
