How to skip a field without entering value in c++
<p>In the below code phone number is not mandatory. How can i skip the field? If i press enter it is still waiting for my input. I want to skip the phone number field if necessary. Is that possible in C++.</p>

<pre><code>#include &lt;iostream&gt;
using namespace std;

int main()
{ 
string id,name,phone,dob;
cout&lt;&lt;"Enter id";
cin&gt;&gt;id;
cout&lt;&lt;"Enter name";
cin&gt;&gt;name;
cout&lt;&lt;"Enter phone number";
cin&gt;&gt;phone;
cout&lt;&lt;"Enter date of birth";
cin&gt;&gt;dob;
}
</code></pre>
