有以下程序 #include <string.h> struct STU int hum; float TotalScore; ; void f(struct STU p) struct STU s[2]=20044,550,20045,537; p.num=s [1].num; p.TotalScore-s[1].TotalScore; main() struct STU s[2]-20041,703,20042,580; f(s[0]); printf( %d %3.0f n ,s[0].num,s[0].TotalScore); 程序运行后的输出结果是
A.20045 537
B.20044550
C.20042580
D.20041 703
