    Lightbulb Could you help me with my research? (Related to data structures)

    good morning C programmers, I am taking data structures, I need to do a research on "The application of stacks in an image editing software", and I have not been able to find anything on the subject, someone could help me or give me ideas, I would appreciate it.

    Undo/redo could use two stacks.

    Each new operation pushes the action onto the undo stack.

    Each undo pops off the undo stack (reverse the action), and pushes it onto the redo stack (so you can do it again if necessary).
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
