I am a newbie in C++ programming. When compiling I never use any option. This is my day to day command: <pre class="prettyprint"><code>g++ MyCode.cc -o MyCode </code></pre> For safety practice what's the best option to use?

<pre class="prettyprint"><code>g++ -W -Wall -Werror </code></pre> Will display all errors and warnings possible and treat them as errors.

What's your favorite g++ option? [closed]

“-Werror”: treats all warnings as errors so you have to fix them. Incredibly valuable.
