The primary reason we are still using and teaching null terminators is because we still have to live with POSIX&amp;#x2F;Win32 and many low-level libraries written on this platform.</text><parent_chain><item><author>stevekemp</author><text>Compared to writing code in assembly language it is a dream, though!&lt;p&gt;I think C lets you think about low-level details of how systems work, strings being arrays of characters with an explicit terminating NUL character, for example.

<instructions>Your goal is to analyze the following comment and estimate how highly it will be upvoted by the Hacker News community.</instructions><comment><author>Beltalowda</author><text>It&amp;#x27;s useful to know how things like strings and arrays work and that they&amp;#x27;re not just &amp;quot;magic&amp;quot;, but I don&amp;#x27;t think you really need to learn C to do that. I understood that kind of stuff long before I did any serious C programming, and knowing C didn&amp;#x27;t really add much to that. The thing is that I don&amp;#x27;t want to think about it &lt;i&gt;every time&lt;/i&gt;.&lt;p&gt;I &amp;quot;just&amp;quot; want to do X, but instead I need to write a whole bunch of code to handle it all manually. It&amp;#x27;s useful that this is possible, but a lot of times you don&amp;#x27;t need it, and some other languages still keep the &amp;quot;common case&amp;quot; easy while still enabling the high-performance stuff C can do.&lt;p&gt;I wish we had C+: C + a few niceties (and not C ++ everything). There&amp;#x27;s a whole bunch of newer languages aiming at the space C is sitting in, but with a few additions C could be much more ergonomic without having to invent an entire new language.</text><parent_chain><item><author>stevekemp</author><text>Compared to writing code in assembly language it is a dream, though!&lt;p&gt;I think C lets you think about low-level details of how systems work, strings being arrays of characters with an explicit terminating NUL character, for example.
