What are the different compiler options available in C++?

What are the different compiler options available in C++?

In C++, compiler options can vary by compiler, but common options include optimization levels, debugging information, and warning levels.

Can you explain what optimization levels are?

Optimization levels control how much the compiler optimizes the code for performance. Common levels are -O0 (no optimization), -O1, -O2, and -O3, with -O3 being the most aggressive.

What does the -g option do?

The -g option generates debug information in the compiled executable, which is useful for debugging with tools like gdb.

Are there any options for enabling warnings?

Yes, you can use options like -Wall to enable all warnings, or -Wextra for additional warnings that are not included in -Wall.
