A question about constructor function

[flysnow]

class T
{
public:
int m_i ;
T () { m_i = 1 ; }
T(int k ) { T() ; }
};

int main()
{
T t(0 );
cout<< t.m_i <<endl;
return 0;
}
When i invoke a constructor funciton within another constructor funciton , this constructor will not impact on this object .

In the above sample code , The t.m_i will remain uninitialize . why
? i test it in VC6.

I have gone throught the ISO C++ specificaiton , but no any thread was been found .
