What are the key components of a C++ compiler?

A C++ compiler typically consists of several key components: the lexer, parser, semantic analyzer, optimizer, and code generator.

Can you explain what each of these components does?

Sure! The lexer breaks the source code into tokens, the parser checks the syntax, the semantic analyzer ensures meaning, the optimizer improves performance, and the code generator produces machine code.

How does the optimization process work in a C++ compiler?

Optimization involves analyzing the code to improve efficiency, such as reducing execution time or memory usage, often through techniques like loop unrolling or dead code elimination.

What are some common challenges faced in compiler design?

Common challenges include handling complex language features, ensuring portability, optimizing performance, and managing memory effectively.
