数据结构上机答案（c语言版）
数据结构上机答案（c语言版）实习一：1、编写一个读入一个字符串，把它存入一个链表，并按相反的次序打印的程序。
2、设有一个单位的人员工资有如下信息：name、department、base pay、allowance、total。
现从键盘输入一组人员工资数据并将它们存储到名为paydata的文件中；再从paydata取出工资数据并给每个人的base pay增加100元，增加后将工资数据显示于屏幕(每行1人)。
请编写能够完成上述工作的程序。
代码如下：1.#include#include#includevoid main(){char x;struct node //定义个结构node{char c;struct node *next;};struct node *head,*pb,*pf,*p,*s,*t; //定义指针printf("请输入字符串，按Enter结束！\n");for(int i=0;x!='\n';i++){pb=(struct node *)malloc(sizeof(struct node));//动态分配n字节的内存空间scanf("%c",&pb->c); //输入字符x=pb->c;if(i==0){ //输入的首个字符作为头结点pfhead=pb;pf=head;}else if(pb->c!='\n'){ //如果输入的是Enter，输入终止，否则把字符依次存入链表pf->next=pb; //把输入的字符pb存在pf后，pb后为空pb->next=NULL;pf=pb;//pb赋给pf，重复上述操作p=head;}}for(;p!=NULL;p=p->next)s=p; //把指向链表的最后一个字符的指针赋给sprintf("输出结果为：\n");printf("%c",s->c);//输出链表的最后一个字符for(p=head;s!=head;)//若s==head，该链表只有一个字符。

实验一 线性表的顺序存储实验
一,实验目的
1,掌握用Visual C++6.0上机调试顺序表的基本方法
2,掌握顺序表的基本操作,插入,删除,查找,以及有序顺序表的合并等算法的实现
二,实验内容
1,顺序表基本操作的实现
[问题描述] 当我们要在顺序表的第i个位置上插入一个元素时,必须先将顺序表中第i个元素之后的所有元素依次后移一个位置,以便腾空一个位置,再把新元素插入到该位置.若是欲删除第i个元素时,也必须把第i个元素之后的所有元素前移一个位置.

数据结构的研究不仅涉及到计算机硬件的研究范围，而且和计算机软件的研究有密切的关系，可以认为数据结构是介于数学、计算机硬件和计算机软件三者之间的一门核心课程。
在计算机科学中，数据结构不仅是一般程序设计的基础，而且是设计和实现编译程序、操作系统、数据库系统及其它系统程序和大型应用程序的重要基础，它的主要任务是讨论各种数据结构的逻辑结构，存储结构及有关操作的算法。
目的是使学生学会分析研究计算机加工的数据结构的特性，以便为应用涉及的数据选择适当的逻辑结构、存储结构及相应的算法，并初步了解对算法的时间分析和空间分析技术。
另一方面，通过对本课程算法设计和上机实践的训练，还应培养学生的数据抽象能力和程序设计的能力。
从而为提高学生的实际分析问题和解决问题的编程能力打下基础。

《数据结构实验指导书》答案实验一：1、请编写函数int fun(int *a, int *b),函数的功能是判断两个指针a和b所指存储单元的值的符号是否相同；若相同函数返回1，否则返回0。
这两个存储单元中的值都不为0。
在主函数中输入2个整数、调用函数fun、输出结果。
#include <stdio.h>int fun(int *a, int *b){if (*a*(*b)>0) return(1);else return(0);}main(){int x,y;scanf("%d%d",&x,&y);if (fun(&x,&y)) printf("yes\n");else printf("no");}2、计算1+2+3+……+100，要求用指针进行设计。
即设计函数int fun(int *n)实现求1+2+3+……+*n，在主函数中输入、调用、输出结果。
#include <stdio.h>int fun(int *n){int i,sum=0;for (i=1;i<=*n;i++)sum+=i;return(sum);}main(){int x,sum;scanf("%d",&x);printf("the sum is %d\n",fun(&x));}3、函数的功能是求数组a中最大数的位置（位序号）。
在主函数中输入10个整数、调用函数fun、输出结果。
#define N 10#include <stdio.h>void input(int *a,int n){int i;for (i=0;i<n;i++)scanf("%d",a+i); /*scanf("%d",&a[i]);*/}int fun(int *a,int n){int i,*max;max=a;for (i=1;i<n;i++)if (a[i]>*max) max=a+i;return(max-a);}main(){int a[N],maxi;input(a,N);maxi=fun(a,N);printf("\n the max position is %d\n",maxi);}4、请编写函数fun(int *a,int n, int *odd, int *even),函数的功能是分别求出数组a中所有奇数之和和所有偶数之和。
形参n给出数组中数据的个数；利用指针odd和even分别返回奇数之和和偶数之和。
在主函数中输入10个整数、调用函数fun、输出结果。
