#include <stdio.h>

typedef struct { int b, p; } A; 

void f(A c) /* 注意：c是结构变量名 */ {

 int j; c.b += 1; c.p+=2; }

main() { 

 i; A a={1,2}; 

f(a); 

printf("%d,%d\n", a.b, a.p); } 

程序运行后的输出结果是

Struct S { int

A, b; } data[2]={10,100,20,200};

Main() {

Struct S p=data[1]; printf("%d\n", ++(p.a) ); }

程序运行后的输出结果是

Struct complex { int real,unreal;}

Data1={1,8},data2;

则以下赋值语句中错误的是

Struct S{int n;int a[20];};

Voidf (struct S *p)

{int i,j,t;

For(i=0；i<p->n-1;i+ +)

For(j=i+1;j<p->n;j+ +)

If(p->a[i]>p->a[j]){t=p->a[i];p->a[i]=p->a[j];p->a[j]=t;}

}

Main( )

{ int i; struct S s={10,{2,3,l,6,8,7,5,4,10,9}};

F(&s);

For(i=0;i<s.n;i+ +) printf("%d,",s.a[i]);

}

#include <stdio.h>

#include <string.h>

typedef struct{char name[9]; char sex; int score[2]; }STU;

STU f(STU a)

{  STU b={"Zhao",'m',85,90};

   int i;

   strcpy(a.name,b.name);

   a.sex=b.sex;

   for(i=0;i<2;i++) a.score[i]=b.score[i];

   return a;

}

main()

{  STU c={"Qian",'f',95,92},d;

   d=f(c);

   printf("%s,%c,%d,%d,",d.name,d.sex,d.score[0],d.score[1]);

   printf("%s,%c,%d,%d,",c.name,c.sex,c.score[0],c.score[1]);

}

若有以下程序段：

q=s; s=s->next; p=s;

while(p->next) p=p->next;

p->next=q; q->next=NULL;

该程序段实现的功能是

# include <stdio.h>

# include <string.h>

Struct A

{ int a; char b[10]; double c;};

Struct A f(struct A t);

Main()

{ struct A a={1001,"ZhangDa",1098.0};

a=f(a); printf("%d,%s,%6.1f\n",a.a,a.b,a.c);

}

Struct A f(Struct A t)

{ t.a=1002; strcpy(t.b,"ChangRong");t.c=1202.0;return t;}

程序运行后的输出结果是
