Syntax:

<pre class="c code c++" style="font-family:monospace;"> <span class="co2">#include <cstdlib></span>
<span class="kw4">int</span> system<span class="br0">(</span> <span class="kw4">const</span> <span class="kw4">char</span> <span class="sy0">*</span>command <span class="br0">)</span><span class="sy0">;</span></pre>
<p>
The system() function runs the given command by passing it to the default
command interpreter.
The return value is usually zero if the command executed without errors. If
command is NULL, system() will test to see if there is a command interpreter
available. Non-zero will be returned if there is a command interpreter
available, zero if not.
