title: how to set string b to equal a when a has spaces in it c
body: <p>I have a string called that can continue a value with spaces for it as an example</p>
  
  <pre><code>char *a="this is a test"
  </code></pre>
  
  <p>I want to declare another string</p>
  
  <pre><code>char *b=NULL;
  </code></pre>
  
  <p>so I can then assign the value of a to b such as </p>
  
  <pre><code>b=a;
  </code></pre>
  
  <p>however currently b will only hold any characters up to the first space (in this example b= "this").
  How do I get it to hold the entire string </p>
