title: Making -std=c++11 the default in mac terminal
body: <p>When I want to compile, I need to specify <code>-std=c++11</code> like this:</p>
  
  <pre><code>g++ -Wall -std=c++11 main.cpp -o main
  </code></pre>
  
  <p>and I wonder if there was a solution to set the -std=c++11 flag permanently so it will be possible to do:</p>
  
  <pre><code> g++ -Wall main.cpp -o main
  </code></pre>
  
  <p>without flags.</p>
