若有以下定义和语句:struct student { int age,num ; }; struct student stu[3]={{1001,20},{1002,19},{1003,21}}; int main() { struct student *p=stu; … }则以下正确的引用是()。
A: (p++)->num
B: ++p->num
C: (*p).num
D: p->num
A: (p++)->num
B: ++p->num
C: (*p).num
D: p->num
举一反三
- 若有以下定义和语句:struct student{ int num ; int age ;} ;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: (p+ + )->; age B: p + + C: (*p).age D: p = &stu. num
- 有以下定义和语句: struct student { int age; int num; }; struct student stu[3]={{1001,20},{1002,19},{1003,21}}; void main() { struct student *p; p=stu; …… } 则以下不正确的引用是
- 若有以下程序段,则使用错误的选项是( ).struct student{int num;int age;};struct student stu[3]={{1001,20},{1002,19},{1004,20}};main();{struct student *p;p=stu;…} A: p=stu.age B: (p++)-num C: (*p).num D: p++
- 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.
- 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
