And here is an article on the boost of my some accumulated materials. I offer you the option of writing a console program with support for the console menu, which is implemented using boost::program_options .

boost::program_options is responsible for processing the arguments passed to the program and sets all the necessary variables without the need to implement long logic from if else branches. This is already implemented inside boost::program_optons .

Suppose our program takes the following data as arguments

• input file path
• output file path
  
• the size of the block being processed, no matter why, we will not do anything with it, just have such a parameter in the program.
  

Also, the program will have a help menu, which will be the console menu.

The figure below shows the use of this program.

After we figured out how to create a menu in the Action Bar, add a context menu to any objects.

In this lesson, we'll add two text fields that will have a context menu.

• The context menu of the first text field will change the color and size of the text in the first text field
  The context menu of the second text box will simply change the text in the second text field.

The first context menu will have two submenus, the first will be responsible for changing the color, and the second will be responsible for resizing.

ActionBar in Java Activity is disabled so that it does not interfere.
