where is the best place to learn making programs with interface?

[poop13]

i can't determinate if i'm a beginner or not on C++ but i want to learn how to make programs with interfaces but i can't seem to find anywhere to learn this

[highwayman]

Do you mean like GUIs or Interfaces as in classes

[poop13]

yes, GUIs, sorry for the wrong use of words, @highwayman.

For GUIs you need to use a framework. Popular ones are wxWidgets, Qt, some newer alternatives ones are:

There are probably many more options. Just Google "C++ GUI"

I use DEV C++ to do stuff but I didn't see anything that would teach me properly to do a C++ application with a GUI, which is an project option on DEV C++ that's why I asked this and I don't know if they give me the proper tools to develop GUI things so I'm sorry if I confuse something or other.

which is an project option on DEV C++

UI development isn't a project option, you need GUI framework which you need to link to your program to use it's headers.

GUI framework is not part a an IDE.

project option on DEV C++

File->New->Project.

In the New Project dialog select Windows application.

The new project is created with generic code to create a Win32 desktop app.

Win32 desktop apps are GUI apps.

Of course coding a Win32 desktop app is rather limiting. Other GUI frameworks can be used on OSes not Windows so a GUI codebase can be easily maintained to be cross-platform.

I meant to ask if you guys knew some sort of documentation for making programs with GUIs, but also, do you guys have a good recommendation of a platform to develop GUIs in C++ that is free and multi platform?

[malibor]

If you strictly want GUI library..
One good C++ GUI with nice interface (code), doesn't force you to use ugly macros, and it compiles with C++ compiler (unlike some which don't but claim to be "C++ libraries") is gtkmm:
https://developer.gnome.org/gtkmm-tutorial/stable/

Another good GUI, which is even better is CEGUI:
http://cegui.org.uk/content/getting-started

my recommendation for a beginner is to use Windows API:
https://docs.microsoft.com/en-us/windows/win32/learnwin32/introduction-to-windows-programming-in-c--?redirectedfrom=MSDN

main difference is:
gtkmm: weak documentation, cross platform, high level library for desktop, binds on C toolkit, open source
CEGUI: horrible documentation, cross platform, medium level library, for desktop and games, open source
Windows API, good documentation, windows only, low level system API, for desktop and games
