title: Best way to format string in C++
body: <p>In <code>javascript</code> I can format a string using <code>template string</code></p>
  <pre><code>const cnt = 12;
  console.log(`Total count: ${cnt}`);
  </code></pre>
  <p>if I work with <code>python</code> I can use the <code>f-string</code>:</p>
  <pre><code>age = 4 * 10
  f'My age is {age}'
  </code></pre>
  <p>But, if I working with <code>C++(17)</code> what is the best solution to do this (if it is possible)?</p>
