What is a C++ compiler and how does it work?

A C++ compiler translates C++ code into machine code that the computer can execute. It processes the source code, checks for errors, and generates an executable file.

What are the main stages of compilation?

The main stages of compilation are preprocessing, compilation, assembly, and linking. Each stage transforms the code into a more executable form.

Can you explain the preprocessing stage?

During the preprocessing stage, the compiler handles directives like #include and #define, preparing the code for the next stages by expanding macros and including files.

What are some common C++ compilers?

Some common C++ compilers include GCC, Clang, and Microsoft Visual C++. Each has its own features and optimizations.

How do I choose the right compiler for my project?

Choosing the right compiler depends on your project's requirements, such as platform compatibility, performance needs, and available features.
