What is the primary method by which C++ source code is converted into an executable program?

• It is directly executed by an interpreter.

• It is first converted into bytecode, then executed by a virtual machine.

• It is compiled into machine code, which is then run as a standalone executable.

• It undergoes just-in-time compilation during runtime.

Which programming language is often chosen for performance-sensitive tasks like gaming and system-level programming?

• Python

• Java

• JavaScript

• C++

Which characteristic best describes Python's code execution model?

• It is compiled into machine code before execution.

• It uses a Just-In-Time (JIT) compiler to optimize bytecode.

• It sends source code directly to an interpreter for on-the-fly execution.

• It requires a specific virtual machine for each operating system.

What is the role of the Just-In-Time (JIT) compiler within the Java Virtual Machine (JVM)?

• To convert Java source code directly into machine code before runtime.

• To interpret Java bytecode line by line during execution.

• To dynamically convert performance-critical bytecode into optimized native machine code right before execution.

• To manage memory allocation and deallocation automatically.
