C语言实现：运动会多校成绩统计与查询系统代码详解

为了满足上述需求，我们需要设计一个C语言程序，包含数据结构定义、输入输出功能以及排序和查询功能。下面是一个实现这些功能的基本框架。 ```c #include <stdio.h> #include <string.h> #define MAX_SCHOOL 20 #define MAX_PROJECT 20 #define NAME_LEN 30 typedef struct { char name[NAME_LEN]; int id; int totalScore; } School; typedef struct { int schoolId; int score; } Score; typedef struct { int projectId; int topCount; // 取前几名 Score winners[5]; // 前五名 } Project; School schools[MAX_SCHOOL]; Project projects[MAX_PROJECT]; void inputSchools(int n) { for (int i = 0; i < n; ++i) { printf("请输入第 %d 所学校的名称和编号：", i + 1); scanf("%s %d", schools[i].name, &schools[i].id); schools[i].totalScore = 0; } } void inputProjects(int m, int w) { int count = 0; for (int i = 0; i < m; ++i) { printf("请输入第 %d 个男子项目的取前几名(3 或 5)及前几名的学校ID和分数：", i + 1); scanf("%d", &projects[count].topCount); for (int j = 0; j < projects[count].topCount; ++j) { scanf("%d %d", &projects[count].winners[j].schoolId, &projects[count].winners[j].score); } projects[count].projectId = i + 1; count++; } for (int i = 0; i < w; ++i) { printf("请输入第 %d 个女子项目的取前几名(3 或 5)及前几名的学校ID和分数：", i + 1); scanf("%d", &projects[count].topCount); for (int j = 0; j < projects[count].topCount; ++j) { scanf("%d %d", &projects[count].winners[j].schoolId, &projects[count].winners[j].score); } projects[count].projectId = m + i + 1; count++; } } void calculateScores() { for (int i = 0; i < MAX_PROJECT; ++i) { for (int j = 0; j < projects[i].topCount; ++j) { int schoolIndex = -1; for (int k = 0; k < MAX_SCHOOL; ++k) { if (schools[k].id == projects[i].winners[j].schoolId) { schoolIndex = k; break; } } if (schoolIndex != -1) { schools[schoolIndex].totalScore += projects[i].winners[j].score; } } } } void sortSchools(int n, int sortBy) { for (int i = 0; i < n - 1; ++i) { for (int j = 0; j < n - i - 1; ++j) { if ((sortBy == 1 && schools[j].id > schools[j + 1].id) || (sortBy == 2 && strcmp(schools[j].name, schools[j + 1].name) > 0) || (sortBy == 3 && schools[j].totalScore < schools[j + 1].totalScore)) { School temp = schools[j]; schools[j] = schools[j + 1]; schools[j + 1] = temp; } } } } void querySchool(int schoolId, int projectId) { int found = 0; for (int i = 0; i < MAX_SCHOOL; ++i) { if (schools[i].id == schoolId) { printf("学校：%s 编号：%d 总分：%d\n", schools[i].name, schools[i].id, schools[i].totalScore); found = 1; break; } } if (!found) { printf("未找到指定学校。\n"); return; } for (int i = 0; i < MAX_PROJECT; ++i) { if (projects[i].projectId == projectId) { for (int j = 0; j < projects[i].topCount; ++j) { if (projects[i].winners[j].schoolId == schoolId) { printf("在项目 %d 中获得第 %d 名，分数为 %d。\n", projectId, j + 1, projects[i].winners[j].score); } } break; } } } void queryProject(int projectId) { for (int i = 0; i < MAX_PROJECT; ++i) { if (projects[i].projectId == projectId) { printf("项目 %d 的前%d名学校如下：\n", projectId, projects[i].topCount); for (int j = 0; j < projects[i].topCount; ++j) { printf("%d. 学校：%d 分数：%d\n", j + 1, projects[i].winners[j].schoolId, projects[i].winners[j].score); } break; } } } int main() { int n, m, w; printf("请输入学校数量："); scanf("%d", &n); inputSchools(n); printf("请输入男子项目数量和女子项目数量："); scanf("%d %d", &m, &w); inputProjects(m, w); calculateScores(); while (1) { printf("\n请选择操作：\n1. 按学校编号排序并输出\n2. 按学校名称排序并输出\n3. 按学校总分排序并输出\n4. 查询学校项目情况\n5. 查询项目获奖情况\n6. 退出\n"); int choice; scanf("%d", &choice); switch (choice) { case 1: sortSchools(n, 1); for (int i = 0; i < n; ++i) { printf("学校：%s 编号：%d 总分：%d\n", schools[i].name, schools[i].id, schools[i].totalScore); } break; case 2: sortSchools(n, 2); for (int i = 0; i < n; ++i) { printf("学校：%s 编号：%d 总分：%d\n", schools[i].name, schools[i].id, schools[i].totalScore); } break; case 3: sortSchools(n, 3); for (int i = 0; i < n; ++i) { printf("学校：%s 编号：%d 总分：%d\n", schools[i].name, schools[i].id, schools[i].totalScore); } break; case 4: int schoolId, projectId; printf("请输入要查询的学校编号和项目编号："); scanf("%d %d", &schoolId, &projectId); querySchool(schoolId, projectId); break; case 5: printf("请输入要查询的项目编号："); scanf("%d", &projectId); queryProject(projectId); break; case 6: return 0; default: printf("无效的选择，请重新输入！\n"); break; } } return 0; } ``` 这个程序包含了以下几个部分： - 定义了`School` 和 `Project` 结构体来存储学校信息和项目信息。 - 提供了输入学校信息和项目信息的功能。 - 计算每个学校的总分。 - 实现了按学校编号、名称或总分排序的功能。 - 支持按学校编号查询学校在某项目中的表现。 - 支持按项目编号查询该项目的获奖情况。 ######[AI写代码神器 | 1760点数解答 | 2024-09-06 23:41:36]
