create a file, write texts in it, save it, read its contents

Question

I need instructions, libraries to insert in my program for that.

Thanks in advance for your help.

Answer 1

What programming language are you looking for?

I am sorry to have forgotten that. I am programming in Pascal.

Old School. Nice. :)

You should find what you're looking for here: https://www.tutorialspoint.com/pascal/pascal_files_handling.htm

If you have written some code and it does not quite work, post your code so we can provide personalized help.

Good luck!

Thank you. I see the displayed result, but I wanted it to be a real file on my PC.

----------------------------------
program writeDemo;

type
   StudentRecord = Record
      s_name: String;
end;

var
   Student: StudentRecord;
   f: file of StudentRecord;

begin
   Assign(f,'c:\tmp\students.dat');
   Rewrite(f);
   Student.s_name := 'John Smith';
   Write(f,Student);
   Close(f);
end.

-----------
I can cut and paste the result into a file on my computer, but is there a simpler way to proceed ?

I'm afraid, you're right.

OnlineGDB runs the code "online", on a server, so it does not have access to the file system of your local file system.

However, there is an "Upload File" button on the left of the green RUN button, so you can upload files from your PC.

Similarly, there are  "Download Current File" and "Download All Files" buttons with blue all the way to the right.

And copy-paste, as you've mentioned.

Or you can set up a Pascal environment on your local PC.

Unfortunately, I do not see any other alternative. :(

Thank you so much for your help.
Long years ago, I wrote a part of a Portal compiler in Portal, which was very similar to Modula 2. Therefore, my choice was to write my software in Pascal, instead of current languages. Now, with your help, I have exactly what I wanted to solve my problem with my development.
