有以下程序 #include #include typedef struct stu { char name[10]; char gender; int score; } STU; void f( char name[10],char gender,int score ) { strcpy( name, "Sun" ); gender = ' m'; score=370; } main( ) { STU b={"Zhao", 'm' , 290}, a={"Qian", 'f' , 350}; b=a; printf( "%s,%c,%d," , b.name, b.gender, b.score ); f( b.name, b.gender, b.score ); printf( "%s,%c,%d\n" , b.name, b.gender, b.score ); } 程序运行后的输出结果是 ( )。 A. Qian,f,350,Sun,f,350 B. Qian,f,350,Qian,f,350 C. Qian,f,350,Sun,m,370 D. Zhao,m,290,Sun,m,370
