一维数组实验题:大奖赛现场统分。已知某大奖赛有n个选手参赛,m(m>2)个评委为参赛选手评分(最高10分,最低0分)。统分规则为:在每个选手的m个得分中,去掉一个最高分和一个最低分后,取平均分作为该选手的最后得分。要求编程实现:
(1)根据n个选手的最后得分,从高到低输出选手的得分名次表,以确定获奖名单;
(2)根据各选手的最后得分与各评委给该选手所评分数的差距,对每个评委评分的准确性和评分水准给出一个定量的评价,每位评委的评分方法:(10 -(评委对选手x的评分 - x的得分)^2 的累加和),从高到低输出各评委得分的名次表。
输入提示:
printf(“How many Athletes?”);
scanf("%d", &n); /* 输入选手人数 /
printf(“How many judges?”);
scanf("%d", &m); / 输入评委人数 */
printf("Order of Athletes:\n"); /* 选手得分排序 */ printf("Order of judges:\n"); /* 评委得分排序 */
/* 函数功能:统计参赛选手的得分 */
void CountAthleteScore(int sh[], float sf[], int n, float f[], int m)
printf("\nAthlete %d is playing.", i);
printf("\nPlease enter his number code:");
scanf("%d", &sh[i]);
for (j = 1; j <= m; j++) /* 第j个评委 */
{
printf(“Judge %d gives score:”, j);
printf("Delete a maximum score:%.1f\n", max); printf("Delete a minimum score:%.1f\n", min); /*去掉一个最高分和最低分*/
/* 函数功能:对分数从高到低排序 */
void Sort(int h[], float f[], int n)
/* 函数功能:打印名次表 */
void Print(int h[], float f[], int n)
printf(“order\tfinal score\tnumber code\n”);
printf("%5d\t%11.3f\t%6d\n", i, f[i], h[i]);
/* 函数功能:统计评委的得分 */
void CountJudgeScore(int ph[], float pf[], int m, float sf[], float f[], int n)
程序运行示例如下:
How many Athletes?5
How many judges?5
