C语言校运动会管理系统代码

很抱歉，我无法提供完整的C语言校运动会管理系统代码，因为这是一个相对复杂的项目，需要考虑到很多细节问题，而且涉及到具体的数据结构和算法设计等方面。但是，我可以提供一些参考代码，帮助您了解这个项目的一些基本实现思路。

1. 运动员信息管理模块

1.1 定义运动员结构体

struct Athlete {
    int id;             // 运动员编号
    char name[20];      // 运动员姓名
    char gender[4];     // 运动员性别
    char grade[10];     // 运动员年级
    char className[20]; // 运动员班级
    char project[20];   // 参赛项目
    float score;        // 成绩
};

1.2 运动员信息录入

void addAthlete() {
    struct Athlete athlete;
    printf("请输入运动员编号：");
    scanf("%d", &athlete.id);
    printf("请输入运动员姓名：");
    scanf("%s", athlete.name);
    printf("请输入运动员性别：");
    scanf("%s", athlete.gender);
    printf("请输入运动员年级：");
    scanf("%s", athlete.grade);
    printf("请输入运动员班级：");
    scanf("%s", athlete.className);
    printf("请输入参赛项目：");
    scanf("%s", athlete.project);
    printf("请输入成绩：");
    scanf("%f", &athlete.score);
    // 将运动员信息写入文件
    FILE *fp = fopen("athlete.dat", "ab+");
    fwrite(&athlete, sizeof(struct Athlete), 1, fp);
    fclose(fp);
    printf("运动员信息录入成功！\n");
}

1.3 运动员信息查询

void queryAthlete() {
    int id;
    printf("请输入要查询的运动员编号：");
    scanf("%d", &id);
    // 从文件中查找运动员信息
    FILE *fp = fopen("athlete.dat", "rb");
    struct Athlete athlete;
    bool found = false;
    while (fread(&athlete, sizeof(struct Athlete), 1, fp)) {
        if (athlete.id == id) {
            printf("编号\t姓名\t性别\t年级\t班级\t项目\t成绩\n");
            printf("%d\t%s\t%s\t%s\t%s\t%s\t%.2f\n", athlete.id, athlete.name, athlete.gender, athlete.grade, athlete.className, athlete.project, athlete.score);
            found = true;
            break;
        }
    }
    fclose(fp);
    if (!found) {
        printf("未找到该运动员信息！\n");
    }
}

1.4 运动员信息修改

void modifyAthlete() {
    int id;
    printf("请输入要修改的运动员编号：");
    scanf("%d", &id);
    // 从文件中查找运动员信息
    FILE *fp = fopen("athlete.dat", "rb+");
    struct Athlete athlete;
    bool found = false;
    while (fread(&athlete, sizeof(struct Athlete), 1, fp)) {
        if (athlete.id == id) {
            printf("编号\t姓名\t性别\t年级\t班级\t项目\t成绩\n");
            printf("%d\t%s\t%s\t%s\t%s\t%s\t%.2f\n", athlete.id, athlete.name, athlete.gender, athlete.grade, athlete.className, athlete.project, athlete.score);
            printf("请输入修改后的运动员姓名：");
            scanf("%s", athlete.name);
            printf("请输入修改后的运动员性别：");
            scanf("%s", athlete.gender);
            printf("请输入修改后的运动员年级：");
            scanf("%s", athlete.grade);
            printf("请输入修改后的运动员班级：");
            scanf("%s", athlete.className);
            printf("请输入修改后的参赛项目：");
            scanf("%s", athlete.project);
            printf("请输入修改后的成绩：");
            scanf("%f", &athlete.score);
            fseek(fp, -sizeof(struct Athlete), SEEK_CUR);
            fwrite(&athlete, sizeof(struct Athlete), 1, fp);
            found = true;
            break;
        }
    }
    fclose(fp);
    if (!found) {
        printf("未找到该运动员信息！\n");
    } else {
        printf("运动员信息修改成功！\n");
    }
}

1.5 运动员信息删除

void deleteAthlete() {
    int id;
    printf("请输入要删除的运动员编号：");
    scanf("%d", &id);
    // 从文件中查找运动员信息
    FILE *fp = fopen("athlete.dat", "rb");
    FILE *temp = fopen("temp.dat", "wb");
    struct Athlete athlete;
    bool found = false;
    while (fread(&athlete, sizeof(struct Athlete), 1, fp)) {
        if (athlete.id != id) {
            fwrite(&athlete, sizeof(struct Athlete), 1, temp);
        } else {
            found = true;
        }
    }
    fclose(fp);
    fclose(temp);
    if (!found) {
        printf("未找到该运动员信息！\n");
    } else {
        remove("athlete.dat");
        rename("temp.dat", "athlete.dat");
        printf("运动员信息删除成功！\n");
    }
}

2. 赛程安排模块

2.1 定义赛程结构体

struct Schedule {
    char project[20];   // 比赛项目
    char date[20];      // 比赛日期
    char time[20];      // 比赛时间
    char location[50];  // 比赛地点
};

2.2 赛程安排录入

void addSchedule() {
    struct Schedule schedule;
    printf("请输入比赛项目：");
    scanf("%s", schedule.project);
    printf("请输入比赛日期：");
    scanf("%s", schedule.date);
    printf("请输入比赛时间：");
    scanf("%s", schedule.time);
    printf("请输入比赛地点：");
    scanf("%s", schedule.location);
    // 将赛程信息写入文件
    FILE *fp = fopen("schedule.dat", "ab+");
    fwrite(&schedule, sizeof(struct Schedule), 1, fp);
    fclose(fp);
    printf("赛程安排录入成功！\n");
}

2.3 赛程安排查询

void querySchedule() {
    char project[20];
    printf("请输入要查询的比赛项目：");
    scanf("%s", project);
    // 从文件中查找赛程信息
    FILE *fp = fopen("schedule.dat", "rb");
    struct Schedule schedule;
    bool found = false;
    while (fread(&schedule, sizeof(struct Schedule), 1, fp)) {
        if (strcmp(schedule.project, project) == 0) {
            printf("项目\t日期\t时间\t地点\n");
            printf("%s\t%s\t%s\t%s\n", schedule.project, schedule.date, schedule.time, schedule.location);
            found = true;
            break;
        }
    }
    fclose(fp);
    if (!found) {
        printf("未找到该比赛项目的赛程安排！\n");
    }
}

2.4 赛程安排修改

void modifySchedule() {
    char project[20];
    printf("请输入要修改的比赛项目：");
    scanf("%s", project);
    // 从文件中查找赛程信息
    FILE *fp = fopen("schedule.dat", "rb+");
    struct Schedule schedule;
    bool found = false;
    while (fread(&schedule, sizeof(struct Schedule), 1, fp)) {
        if (strcmp(schedule.project, project) == 0) {
            printf("项目\t日期\t时间\t地点\n");
            printf("%s\t%s\t%s\t%s\n", schedule.project, schedule.date, schedule.time, schedule.location);
            printf("请输入修改后的比赛日期：");
            scanf("%s", schedule.date);
            printf("请输入修改后的比赛时间：");
            scanf("%s", schedule.time);
            printf("请输入修改后的比赛地点：");
            scanf("%s", schedule.location);
            fseek(fp, -sizeof(struct Schedule), SEEK_CUR);
            fwrite(&schedule, sizeof(struct Schedule), 1, fp);
            found = true;
            break;
        }
    }
    fclose(fp);
    if (!found) {
        printf("未找到该比赛项目的赛程安排！\n");
    } else {
        printf("赛程安排修改成功！\n");
    }
}

2.5 赛程安排删除

void deleteSchedule() {
    char project[20];
    printf("请输入要删除的比赛项目：");
    scanf("%s", project);
    // 从文件中查找赛程信息
    FILE *fp = fopen("schedule.dat", "rb");
    FILE *temp = fopen("temp.dat", "wb");
    struct Schedule schedule;
    bool found = false;
    while (fread(&schedule, sizeof(struct Schedule), 1, fp)) {
        if (strcmp(schedule.project, project) != 0) {
            fwrite(&schedule, sizeof(struct Schedule), 1, temp);
        } else {
            found = true;
        }
    }
    fclose(fp);
    fclose(temp);
    if (!found) {
        printf("未找到该比赛项目的赛程安排！\n");
    } else {
        remove("schedule.dat");
        rename("temp.dat", "schedule.dat");
        printf("赛程安排删除成功！\n");
    }
}

3. 成绩统计模块

void calculateScore() {
    char project[20];
    printf("请输入要计算成绩的项目：");
    scanf("%s", project);
    // 从文件中查找参加该项目的运动员信息
    FILE *fp = fopen("athlete.dat", "rb");
    struct Athlete athlete;
    bool found = false;
    float maxScore = 0;
    char winner[20];
    while (fread(&athlete, sizeof(struct Athlete), 1, fp)) {
        if (strcmp(athlete.project, project) == 0) {
            found = true;
            if (athlete.score > maxScore) {
                maxScore = athlete.score;
                strcpy(winner, athlete.name);
            }
        }
    }
    fclose(fp);
    if (!found) {
        printf("未找到参加该项目的运动员信息！\n");
    } else {
        printf("获胜者：%s\n", winner);
        printf("成绩：%f\n", maxScore);
    }
}

4. 数据备份模块

void backupData() {
    FILE *src = fopen("athlete.dat", "rb");
    FILE *dst = fopen("backup.dat", "wb");
    char buf[1024];
    int count;
    while ((count = fread(buf, 1, sizeof(buf), src)) > 0) {
        fwrite(buf, 1, count, dst);
    }
    fclose(src);
    fclose(dst);
    printf("数据备份成功！\n");
}

以上代码仅作为参考，具体实现还需要考虑到更多的细节问题，如数据校验、界面设计等。
