Q101.

What is the output of following program?

template <typename T>
void test(const T&x) 
{
    static int count = 0;
    cout &lt;&lt; "x = " &lt;&lt; x &lt;&lt; " count = " &lt;&lt; count &lt;&lt; endl;
    ++count;
    return;
}
 
void main() 
{
    test<int> (2);
    test<int>(2);
    test<double>(2.2);
}

x = 2 count = 0
x = 2.2 count = 0
x = 2.2 count = 0

x = 2 count = 0
x = 2 count = 0
x = 2.2 count = 0

x = 2 count = 0
x = 2 count = 1
x = 2.2 count = 0

x = 2 count = 0
x = 2 count = 1
x = 2.2 count = 2

Discuss
