"0" From nowhere after cout : <p>When i compile and run the program i am getting:The year you were born: 0
Where is the "0" coming from??
Here is the code:</p>

<pre><code>//! Program written by Samer!//
#include &lt;iostream&gt;
using namespace std;
int main() 
{

double Year, Age;
cout &lt;&lt;"The year you were born: "&lt;&lt; Year;  //!Here the error appears!//
cin &gt;&gt;Year; 
while (Year &gt; 2017) //!That't a While loop!//
{
    cout &lt;&lt;"Please enter a valid Year:" &lt;&lt; Year &lt;&lt; endl;
    cin &gt;&gt;Year;
}
 Age=2017-Year;
cout &lt;&lt;"Your age is:" &lt;&lt;Age;
std::cin.get();
return 0;
}
</code></pre>
