When you REALLY miss C++

being honest when I miss C++, I Mess C++

Don’t forget to return self :-)

When I first learned about “stream” operators C++, I really liked it. But over time I found out how annoying they really are when I used Python’s f-strings or Rust’s format! or print! macros or even “good old” C’s printf. It’s ridiculous how much boilerplate code we need to write to format floating point numbers. Now I use std::format whenever possible.
Compare these:
The “old” C++ way:
<pre><code class="language-C++">#include &lt;iostream&gt;
#include &lt;iomanip&gt;

int main() {
 float num = 3.7f;
 std::cout &lt;&lt; std::fixed &lt;&lt; std::setprecision(1) &lt;&lt; std::setw(4) &lt;&lt; std::setfill(&#x27;0&#x27;) &lt;&lt; num &lt;&lt; &#x27;\n&#x27;;
 return 0;
}
</code></pre>
And the new C++20 way (sadly there is not a good support across compilers yet):
<pre><code class="language-C++">#include &lt;iostream&gt;
#include &lt;format&gt;

int main() {
 float num = 3.7f;
 std::cout &lt;&lt; std::format(&quot;{:04.1f}\n&quot;, num);
 return 0;
}
</code></pre>
And C++23 has std::print:
<pre><code class="language-C++">#include &lt;print&gt;

int main() {
 float num = 3.7f;
 std::print(&quot;{:04.1f}\n&quot;, num);
 return 0;
}
</code></pre>

I do mi-C. Get it? it sounds like miss… okay nvm T_T

also use end=“” and return self
