title: How to make g++ to show the execution time in terminal?
body: <p>I want to make g++ showing me what is the execution time and maybe the return too.</p>
  
  <pre><code>g++ file.cpp -o file
  ./file
  </code></pre>
  
  <p>When i make the executable file and then call in it is showing only the output without the return and execution time.</p>
  
  <p>And i want to make it showing something like this:</p>
  
  <pre><code>Process returned 0 (0x0)    execution time : 0.002 s
  </code></pre>
  
  <p>Thank you for the attention!</p>
