有以下程序
struc STU {
char name[10];
int num; };
void f1(struct STU c)
{ struct STU b={“LiSiGuo”,2042};
c=b; }
void f2(struct STU *c)
{ struct STU b={“SunDan”,2044};
*c=b; }
main()
{ struct STU a={“YangSan”,2041},b={“WangYin”,2043 };
f1(a);f2(&b);
printf(“%d %dn”,a.num,b.num); }
执行后的输出结果是()
A．2041 2044
B．2041 2043
C．2042 2044
D．2042 2043
