有以下程序:#include < stdio. h >typedef struct stu {char name[ 10];char gender;int score;}STU;void f(STU a, STU * b){ * b = a;printf(" % s,% c,% d," , b -> name, b -> gender, b -> score);}main(){ STU a = { "Zhao" , 'm', 290} , b = { "Qian" , ’f', 350); f(a,&b);printf( "%s,%c,%d\n" , b.name, b.gender,b.score);}程序运行后的输出结果是()。
A. Zhao, m, 290, Qian, f, 350
B. Qian, m, 290, Zhao, m, 290
C. Qian, f, 350,Qian, f, 350
D. Zhao,m, 290, Zhao,m,290
