若有以下程序 #include #include #include typedef struct stu { char *name, gender; int score; } STU; void f(char *p) { p=(char *)malloc(10); strcpy(p, "Qian"); } main() { STU a={NULL, 'm', 290}, b; a.name=(char *)malloc(10); strcpy( a.name, "Zhao" ); b = a; f(b.name); b.gender = 'f'; b.score = 350; printf("%s,%c,%d,", a.name, a.gender, a.score); printf("%s,%c,%d\n", b.name, b.gender, b.score); } 则程序的输出结果是
