若有以下定义的语句: struct student int age; int num;; struct student stu[3]=1001,20,1002,19,1003,21; main() struct student *p; p=stu; … 则以下不正确的引用是( )。
A: A) (p++)->num
B: B) p++
C: C) (*p).num
D: D) P=&stu.age.
A: A) (p++)->num
B: B) p++
C: C) (*p).num
D: D) P=&stu.age.
举一反三
- struct Student{int num;int age;};int main(){struct Student stu[3] = {{1101, 18}, {2892, 19}, {3000, 20}};struct Student *p = stu;...} 若有定义和语句,则不正确的引用是( ) A: (p++)->num B: p=&stu.age C: p++ D: (*p).num
- struct student{ int age; char num[8];};struct student stu[3]={{20,"200401"},{21,"200402"},{19,"200403"}};struct student *p=stu;以下选项中引用错误的是___ __。 A: (p++)->;num B: p->;num C: (*p).num D: stu[3].age
- 若有以下定义语句:struct student{ int num,age;};struct student stu[3]={{101,20},{102,19},{103,18}},*p=stu;则以下错误的引用是( ) A: (p++)->num B: p++ C: (*p).num D: p=&stu.age
- 若有以下定义语句,则以下错误的引用是( )。struct student{ int num,age;};struct student stu[3]={{101,20},{102,19},{103,18}},*p=stu; A: (p++)->num B: p++ C: (*p).num D: p=&stu.age
- 若有以下定义和语句: struct student {int num ;int age;}; struct student stu[3]={{l001,20},{1002,19},{1003,2l}}; main() {struct student *p;p=stu; ... } 则下列引用中不正确的是(A)。 A: (p++)→num B: p++ C: (*p).num D: p=&stu.age
