7、新的类型 B)可以用typedef将已存在的类型用一个新的名字来代表 C)用typedef定义新的类型名后，原有类型名仍有效 D)用typedef可以为各种类型起别名，但不能为变量起别名(12) 2008.4.29以下正确的是 A)typedef struct int n; char c; S; S t1, t2;B)struct Sint n; char c;S t1, t2; C)typedef struct S int n = 0; char c = 'A' t1, t2; D)struct int n; char c; S; S t1, t2;(13) 2004.4.3

8、92006.9.442010.9.39以下叙述中正确的是 typedef struct S int g; char h; T; A)可用S定义结构体变量 B)可用T定义结构体变量 C)S是struct类型的变量 D)T是struct S类型的变量(14) 2007.4.47以下正确的是 typedef struct node int data; struct node *next; *NODE; NODE p; A)p是指向struct node结构变量指针的指针 B)NODE p; 语句出错 C)p是指向struct node结构变量的指针 D)p是struct node结构变量(15) 2

9、007.4.332009.9.14程序运行结果是 typedef struct int b, p; A; void f(A c) c.b += 1; c.p += 2; main() A a = 1,2; f(a); printf("%d,%d", a.b, a.p); (16) 2010.3.37程序运行结果是 struct A int a; char b10; double c; ; void f(struct A t) t.a = 2; t.c = 2.2; strcpy(t.b,"Li"); main() struct A a = 1,"
