C string diff a la Python's difflib

creating a c++ string diff utility (similar to python's difflib)
in this tutorial, we will create a c++ string diff utility inspired by python's difflib module. this utility will allow you to compare two strings and visualize the differences between them in a human-readable format. we'll use c++ to implement the logic, and we won't require any external libraries.
before we start, make sure you have a basic understanding of c++ and have a c++ compiler installed on your system.
create a new c++ project or a c++ source file, and include the necessary headers:
we'll define a function named diff that takes two strings as input and returns a vector of string differences. each difference will be represented as a line of text with markers to indicate added, removed, or unchanged content.
we will implement a simple algorithm to find the differences between two strings. you can use a more advanced algorithm like the longest common subsequence (lcs) if needed, but for this tutorial, we'll use a basic approach.
now, let's create a function to display the differences in a human-readable format.
in your main function, you can test your utility with two sample strings and display the differences.
compile your c++ code using your preferred compiler (e.g., g++) and run the program. you should see the differences between the two strings displayed in the console.
that's it! you've created a simple c++ string diff utility similar to python's difflib. you can now use and expand upon this code for more complex text comparison tasks.
