下列程序的输出结果是 #include class Myclass {
public:Myclass(int i=0,intj=0) { x=i;
y=j; } void show( ) { cout < < "x=" < < x
< < " " < "y=" < < y < < end1;} void show( )const { cout < < "x=" <
< " " < < "y=’ < < y < < end1;} privated:
int x; int y; }; void main(
) { Myclass my1(3,4); const my2(7,8);
my1.show( );my2.show( );}
A.x=4,y=3;x=7,y=8
B.x=3,y=4;x=7,y=8
C.x=7,y=8;x=4,y=3
D.x=8,y=7;x=7,y=8
