I'm new to programming and I've been learning for about two months. I know how to read from a text file and write to a new one, but I'm stuck on how to ignore certain parts of the text. For instance, if I have a line that reads 'abcd1456-23 50y I love you', I want to extract only 'I love you' for my output file. Also, I'm using C++ with Visual Studio for this. Any guidance would be appreciated!

What are the rules for filtering the text? For example, should you only take the last three words or everything after a certain character in the line? If you can clarify that, it would be easier to help you get the right output!
If the data you need to exclude is in specific positions, you might be able to simply split the string and format it. Just make sure you account for any extra spaces or irregularities in the original text to avoid confusion.
Have you looked into using Regular Expressions (regex)? They can be quite handy for isolating specific strings or patterns in your text!
Not yet, but I’m interested! Can you point me to some resources?
It sounds like you're transforming input lines into a specific format, right? If the text 'I love you' appears anywhere in the line, you may want to build your logic around that. Try using substring functions to get the text you need after verifying that the phrase is present.
Definitely! Make sure to clarify how your input is structured to get precise instructions.
You should consider specifying the structure of your input lines clearly. Once you know that, you can utilize string functions in C++ to extract what you need.
