下面结构体的定义如下：struct student{ char name[32]; struct date{ int day; int month; int year; }birthday;};错误的初始化语句是： A: struct student s1={'Li',1,1,2000}; B: struct student s1={"Li",{1,1,2000}}; C: struct student s1={"Li",1,1,2000}; D: struct student s1={"Li",1,1};

‌下面结构体的定义如下：‎‌struct student{‎‌ char name[32];‎‌ struct date{‎‌ int day;‎‌ int month;‎‌ int year;‎‌ }birthday;‎‌};‎‌错误的初始化语句是：‎ A: struct student s1={'Li',1,1,2000}; B: struct student s1={"Li",{1,1,2000}}; C: struct student s1={"Li",1,1,2000}; D: struct student s1={"Li",1,1};

已知学生记录描述为：struct student { int no ; char name[20]; char sex; struct { int year; int month ; int day ; } birth ; } s ;设结构变量 s 中的“birth”是“1985年10月1日”，则下面正确的赋值方式是( ) A: year=1985 month=10 day=1 B: birth.year=1985birth.month=10birth.day=1 C: s.birth.year=1985s.birth.month=10s.birth.day=1 D: s.year=1985 s.month=10 s.day=1
