how can i extract numerical data from a webpage source code that is embedded in a text file using fortran? (e.g https://www.google.com/finance?q=NYSE:KO) My aim is to retrieve the stock price through the source code. Any help will be appreciated!
Thanks in advance.
Do you really want to do that in Fortran? Fortran is not very well suited for string manipulation (in my opinion)!
I would recommend to get and process the HTML in another language (e.g. Python), and write in the data in a structured way that Fortran can directly read. You could call that script / program from Fortran using the statement
call system('command')

I am using ADTF Libraries to write a structure data. I need to verify whether the data is being written properly. How can i do this?
I am assuming you are writing structured data to a .dat/.adtfdat file. In that case, you can always convert a .dat/.adtfdat file into a csv to verify. See examples on how to do so.
If you have access to MATLAB, then the easiest way would be using a simple function in MATLAB : adtffilereader
Alternatively, there are these tools that help in extracting data out of a dat file.
I have got a trace file that is binary in nature. I want to convert it to a text file and convert the data inside it to decimal form. I mean I am not sure, how to do this. This .trc file contains data in the form of telegrams and I want to extract particular kind of telegram and save them in text file which is readable in nature. I have to do all of this using C++.
Do you suggest any other language for it or does anyone has any idea about doing this in C++?
Binary trace files are usually encoded in proprietary formats. And there are applications or profilers specifically built to parse them.
Unless you know the file format, the only way to decode it is through reverse engineering. And in most cases it's not worth the effort.
Try to find documentation about it. Or maybe an application or utility that loads the file and exports data that is easier to read.
In case you are speaking about .trc binary files from Teledyne Lecroy Oscilloscopes, I would suggest to any of the following libraries out there for that:
https://pypi.org/project/lecroyparser/
https://github.com/jneer/lecroy-reader
https://github.com/yetifrisstlama/readTrc

I need to parse a log file that consist in many screenshot of real-time OS stdout.
In particular, every section of my log_file.txt is a text version of what appear on screen. In this machine there's not monitor, so the stdout is written on a downloadable log_file.txt.
The aim would be to create a .csv of this file for data mining purpose but I'm still wondering what could be the best method to compute this file.
I would the first csv file line with the description (string) of the value and from the second line I would the respective values (int).
I was thinking about a parser generator (JavaCC, ANTLR, etc..) but before starting with them I would get some opinions.
Thank you.
P.S.
I put a short version of my log at the following link: pastebin.com/r9t3PEgb
I tried to build a chatbot in AIML. I downloaded the codes from http://nlp-addiction.com/chatbot/mathbot/ but couldn't get the idea about how to run the program. Please help me.
An AIML file isn't program code, it's a data file (much like any other xml file).
You need to use an interpreter like Program-AB to load and use the file to answer queries.
If you just want to test the contents and formatting of the aiml file, you could use Pandorabots and load the file into a blank bot fairly easily.
Yes, AIML file isn't program code. It's just like a data format. You can learn about it more from here : http://www.alicebot.org/aiml.html
AIML is a data encoding format that tells the bot when to do what to do. Many interpreters can be used to interpret the aiml tags.
One of them is PyAIML which is python based interpreter fairly simple to use.
I am a beginner in visual studio and has only code C and C++ in command line settings.
Currently, I am taking a module(software development) which requires me to come up with an expense tracker - a program which helps user tracks his/her daily expenses. Therefore, at the end of each individual day, or after a user uses finishes the program, we would have to perform data storage to store all the info in one place which we would export it during the next usage.
My constraint include not using any relational database(although i have no idea what it is :( ). Data storage must be done using XML or text files. Following this, I have several questions regarding data storage:
1) If data is stored successfully, do we export it everytime we start the program? And everytime after the user closes the program, we overwrite the existing data file and then store it accordingly?
2) I have heard from some people that using text file may be easier. Searching on the internet and library only provides me with information regarding XML and not text. Would anyone be able to help me with it? Like tutorials link and stuff?
Thank you very much!
File writing/handling works similar to every other buffer in c++.
you can enable file handling using the fstream header. You can create a file, write to it and over-write every time the program is run, or can even create a file the first time the program is run and then append to it every subsequent time the program runs.
Ive only ever done text files, never tried XML, but Im guessing they're similar.
http://www.cplusplus.com/doc/tutorial/files/ should give you everything you need to know.
Your choice of XML vs plain text depends on the kind of data that you'll be storing.
The reason why you'll only find XML libraries on the internet is because XML is a lot more complicated than plain text. If you don't know what XML is or if the data that you're storing isn't very complex, then I would suggest going with plain text.
For example, to track expenses, you might store a file like this:
sandwich 5.00
coffee 2.30
soft drink 1.50
...
It's very easy to read/write lines like this to/from a file in C++.
