实验2 顺序结构程序设计与调试 班 级 学 号 实 验 室 专 业 姓 名 成绩评定 所用软件 计算机号 教师签名 2.1 实验目的
1(熟悉C语言的表达式语句、空语句和复合语句。
2(熟悉函数调用语句，尤其是各输入输出函数的调用语句。 3(熟悉顺序结构程序中语句的执行过程。
4(熟悉程序的跟踪调试和变量值的监视。
5(能设计简单的顺序结构程序。
2.2 实验预习
1(熟悉下列函数:putchar、getchar、printf、scanf 2(了解顺序结构程序的执行过程。
3(了解程序的跟踪调试和变量值的监视并能够熟练操作。
单步跟踪调试(逐条语句跟踪调试):
1)可按功能键F7进行，要监视某变量的值时，就按Ctrl，F7键，然后输入相应的 (
变量名，就可以在监视消息窗口中查看到该变量的值。
(2)也可逐段运行程序，即每次运行若干条语句。首先利用Ctrl，F8键在各行光标
处设置若干断点，然后按Ctrl，F9键从程序的第一条语句运行到设置的第一个断
点，再按Ctrl，F9键从设置的第一个断点运行到设置的第二个断点。 4(了解顺序结构程序的一般构成。

点后两位。已知程序段中有三处错误，由注释语句/**********found**********/提示下一条语句有错误，请修改程序中的错误并记录程序运行结果。
错误原因是 正确语句是 #include
main()
{ float f,c; clrscr();
/**********found(1)**********/
scanf("%d",f);
/**********found(2)**********/
c=5/9(f-32);
/**********found(3)**********/
printf("f=%f,c=%f\n",c,f);
}
3. 已知程序功能是通过用户输入三角形三边，求取三角形面积。填空，将程序补充完整。
求取公式为;S=(a+b+c)/2 area=sqrt(s*(s-a)*(s-b) *(s-c))
人工填空 上机填空
#include
(1) /*需要添加头文件*/
main()
{float a,b,c,s,area;
clrscr();
scanf("%f,%f,%f",&a,&b,&c);
(2);
area=sqrt(3); /*库函数
sqrt的含义是开平方*/
printf("area=%f\n",area);}
4.单步跟踪下面程序的执行，每执行一条语句就查看各变量的值。运行时输入一个三位的整数。单步跟踪程序时填写下表，同时分析程序的功能。

7.3 实验任务
1. 餐饮服务质量调查打分
在商业和科学研究中，人们经常需要对数据进行分析并将结果以直方图的形式显示出来。例如，一个公司的主管可能需要了解一年来公司的营业状况，比较一下各月份的销售收入状况。如果仅给出一大堆数据，这显然太不直观了，如果能将这些数据以条形图(直方图)的形式表示，将会大大增加这些数据的直观性，也便于数据的分析与对比。下面以顾客对餐饮服务打分为例，练习这方面的程序编写方法。假设有40个学生被邀请来给自助餐厅的食品和服务质量打分，分数划分为1,10这10个等级(1表示最低分，10表示最高分)，试统计调查结果，并用*打印出如下形式的统计结果直方图。

2. 大奖赛现场统分
以往各类大奖赛的报分与统分脱节，参赛选手的最后得分总要等到下一个选手赛完后才报，影响竞赛的正常节奏，也不能满足观众的期待心理。现在请你为某大奖赛编写一个现场统分的程序，在各评委打分之后，及时通报评分结果。
已知:某大奖赛有n个选手参赛，m(m>2)个评委为依次参赛的选手评判打分:最高100分，最低0分。统分规则为:每个选手所得的m个得分中，去掉一个最高分，去掉一个最低分，然后平均为该选手的最后得分。要求编程:根据n个选手的最后得分，从高到低排出名次表，以便确定获奖名单。
30
提示:设置数组sf[i]为第i个选手的最后得分。pf[i][j]为第j个评委给第i个选手的评分。
对n个参赛选手设置i循环(i从1变化到n):第i个选手上场，在j循环(j从1变化到m)中依次输入第i个选手的m个得分pf[i][j]，每一个得分pf[i][j]都进行累加，去掉一个最高分max，去掉一个最低分min，第i个选手的最后得分于是为:sf[i] = (sf[i] – max – min) / (m - 2)(2)n个参赛选手的最后得分sf[0]、sf[1]、„、sf[n]全部计算完后，将其从高到低排序，输出打印参赛选手的名次表。
