好吧，各位大神，我又来请教了

#include <iostream.h>
class T
{
public:
/*********found***+******/
T(int x):a(x)
{b+=x;}
/********found**********/
static void display(T c)
{ cout<<"a="<<c.a<<"\t"<<"b="<<b<<endl;}
private:
const int a;
static int b;
};
/**********found*********/
int T::b=5;
void main()
{
T A(3),B(5);
T::display(A);
T::display(B);
}
