如果成员本身又是一个结构体类型,则要用成员 运算符一级一级地找到最低一级的成员 正确引用 struct date struct student student1 num int month: int num studentI birthday day int day char name 20] Int year; char sex Int age; struct date birthday char addr301 S student l, student2
如果成员本身又是一个结构体类型,则要用成员 运算符一级一级地找到最低一级的成员 struct student {int num; char name[20]; char sex; int age; struct date birthday; char addr[30]; }student1,student2; struct date {int month; int day; int year; }; 正确引用: student1.num student1.birthday.day
student2 score=student1, score sum=student1 score+student2 score studentI age++, ++student2 birthday year, “”的优先级最高
student2.score=student1.score; sum=student1.score+student2.score; student1.age+ +; + +student2.birthday.year; “ . ”的优先级最高
可以 scanf( %od, &studentI num) printf( %o, &student2) 不可以 scanf(%od%os%oc%od%of%os, &student)
可以: scanf(“%d”,&student1.num); printf(“%o”,&student2); 不可以: scanf(“%d%s%c%d%f%s”,&student1);
