What are the key differences between C++ and Java features?

C++ is a multi-paradigm language that supports both procedural and object-oriented programming, while Java is primarily object-oriented. C++ allows for operator overloading and multiple inheritance, whereas Java does not support these features.

Can you explain why Java is considered more platform-independent than C++?

Java is platform-independent due to the Java Virtual Machine (JVM), which allows Java code to run on any device that has the JVM installed. C++ is compiled directly to machine code, making it platform-dependent.

What about memory management in C++ compared to Java?

C++ requires manual memory management using pointers and dynamic allocation, which can lead to memory leaks. Java, on the other hand, has automatic garbage collection, which helps manage memory more efficiently.

Which language is better for performance, C++ or Java?

C++ generally offers better performance due to its closer proximity to hardware and less overhead from features like garbage collection. However, Java's performance has improved significantly with modern JVM optimizations.
