iOS 17.2: How to change your iPhone's default notification sound
Dec 15, 2023 am 08:26 AM
In iOS 17.2, Apple lets you customize the sound your iPhone uses for default notifications. This is good news for anyone who doesn't like the "bounce" tone Apple is introducing in iOS 17. In previous iOS versions, Apple allowed users to choose ringtones and text tones, as well as custom alert sounds for email, calendar, and reminder alerts. Anything else that throws notifications uses the default sound, and there's no way to change it. In iOS17, Apple subsequently changed the original default alert sound from "Tri-tone" to "Rebound". Many users didn't like the change, and some thought the new sounds were harder to hear. Therefore, the default sound in iOS17.2 is changed to your

C++ function parameter type safety check
Apr 19, 2024 pm 12:00 PM
C++ parameter type safety checking ensures that functions only accept values of expected types through compile-time checks, run-time checks, and static assertions, preventing unexpected behavior and program crashes: Compile-time type checking: The compiler checks type compatibility. Runtime type checking: Use dynamic_cast to check type compatibility, and throw an exception if there is no match. Static assertion: Assert type conditions at compile time.
What are instance variables in Java
Feb 19, 2024 pm 07:55 PM
Instance variables in Java refer to variables defined in the class, not in the method or constructor. Instance variables are also called member variables. Each instance of a class has its own copy of the instance variable. Instance variables are initialized during object creation, and their state is saved and maintained throughout the object's lifetime. Instance variable definitions are usually placed at the top of the class and can be declared with any access modifier, which can be public, private, protected, or the default access modifier. It depends on what we want this to be
