有以下程序：
#inCluDE ＜iostrEAm＞
using nAmEspACE stD;
ClAss point’
puBliC:
voiD sEtpoint(int x,int y);
voiD movE(int xoFF,int yoFF);
int gEtx()
rEturn x;
int gEty()
rEturn y;
privAtE:
int x,y;
;
voiD point::sEtpoint(int x, int y)
x=x;
y=y;
voiD point: :movE(int xoFF, int yoFF)
x+=xoFF;
y+=yoFF;
int mAin ()
point p1;
p1.sEtpoint(1,2);
p1.movE (5, 6);
Cout＜＜"point1 is ("＜＜p1.gEtx()＜＜’,’＜＜p1.gEty()＜＜")"＜＜EnD1;
rEturn 0;
执行后的输出结果是( )。
A．point1 is (6,8)
B．point1 is (1,2)
C．point1 is (5,6)
D．point1 is (4,4)
