Please information about relation sign and arithmetic sign
I'm not sure what the question is. Could you please elaborate? You can also comment on the Code Playground project to ask the SoloLearner who made the code you linked your question directly.
The Code Playground project you linked doesn't contain arithmetic (and probably doesn't contain relation signs, depending on what that ends up meaning -- probably assignment operators?) so I don't think you're providing accurate context.
when are use in arithmetic and relation sign used
