How to count how many times a word appears in a .txt file

[anonymous_john]

Hello! Ηow to create a program in C ++ where it counts how many times appears a specific word in a  txt file? Can someone help me?

Sounds like homework?

Why would you need a program to complete it? Surely the CTRL+F and Count would work better in Notepad++

A school project? Neowin won't do your homework for you, but we can offer you guidance and point you in the right direction.

I always started with pseudocode before going in to real coding. That way I had an idea of what I wanted to achieve. So let's start with that, what do you want the program to do? If you had to do the job yourself rather than creating a program, how would you count how many times a certain word appears?

So what self-driven learning have you undertaken so far?  I ask this because what you're asking is ridiculously easy, and I struggle to accept that you've even tried so far.

I would suggest Regular Expressions. Research MatchCollections with Regular Expressions in .NET. That should allow you to achieve what you want. Hopefully, that points you in the right direction.

The problem with a question like this is we have no idea what's actually blocking you. Have you ever written any C++? Any program in any language? Do you know how to open a file in C++? Do you know how to compare strings?

 

Show us what you've done and what exactly is blocking you from making progress.

Yes regex is the solution, if you ever need to parse xml I highly suggest using regex  

But seriously, don't parse xml with regex, if you want to spend a whole summer debugging code go for it but I wouldn't recommend it, regex isn't designed to work well with nested tags neither is it made to do everything text related even when it could be done with a simpel for loop. Regex is useful as example if you don't want to search for just a word but for all words that start with neo and end with win.

 

He asked about c++ that's quite a bit different from .NET and all of it's libraries available for it.

.NET is like walking with 2 legs but c++ is not even like walking with 1 leg, it's more like having no legs at all in my experience

Sorry, I was reading in a hurry yesterday. I was trying to help out and work on a project for work at the same time. Probably wasn't the best idea. Thank you for your response! I agree about c++ btw. It can be rough!
