Which of the following is a commonly used compiler for compiling C++ programs?

Correct option is A

GCC (GNU Compiler Collection) is one of the most widely used compilers for C++ and other programming languages like C. It is open-source and supports various platforms, making it a popular choice for both development and learning.
Example of compiling a C++ program:

Important Key Points:
1. GCC is part of the GNU Project and supports multiple languages, including C, C++, Objective-C, Fortran, Ada, and more.
2. Clang, another widely used compiler, is part of the LLVM project and offers better diagnostics and modularity.
3. Other proprietary compilers like Microsoft Visual C++ (MSVC) are used on Windows systems.

· JVM: Not a compiler but an environment to execute Java bytecode.
· PyPy: A JIT (Just-In-Time) compiler for Python.
· CPython: The standard Python interpreter, not related to C++ compilation.
