using namespace std:

class Sample

{

friend long fun ( Sample s ) ;

public:

Sample ( long a ) {x=a;}

Private:

long x;

};

long fun ( Sample s )

{

if ( s.x<2 ) retum 1;

retum s.x*fun ( Sample ( s.x-a ))

}

int main ()

{

int sum=0

for ( int i =0; i <6; i ++ ) { sum+=fun ( Sample ( i ) ; ) }

cout<<SUM;

retum 0;

}

运行时输出的结果是

A ) 120

B ) 16

C ) 154

D ) 34
