统计成绩：给出n个学生的考试成绩表，每条信息由姓名和分数组成，试设计一个算法，按名次列出每个学生的姓名与分数c语言代码

以下是用C语言实现的统计成绩算法：

#include <stdio.h>
#include <string.h>

#define MAX_STUDENTS 100

struct Student {
    char name[20];
    int score;
};

void bubbleSort(struct Student students[], int n);
void printRank(struct Student students[], int n);

int main() {
    struct Student students[MAX_STUDENTS];
    int n;
    printf("Enter the number of students: ");
    scanf("%d", &n);

    // 输入学生姓名和分数
    for (int i = 0; i < n; i++) {
        printf("Enter the name and score of student %d: ", i + 1);
        scanf("%s%d", students[i].name, &students[i].score);
    }

    // 按照分数从高到低排序
    bubbleSort(students, n);

    // 输出排名
    printRank(students, n);

    return 0;
}

void bubbleSort(struct Student students[], int n) {
    for (int i = 0; i < n - 1; i++) {
        for (int j = 0; j < n - i - 1; j++) {
            if (students[j].score < students[j + 1].score) {
                // 交换位置
                struct Student temp = students[j];
                students[j] = students[j + 1];
                students[j + 1] = temp;
            }
        }
    }
}

void printRank(struct Student students[], int n) {
    printf("\nRank\tName\tScore\n");
    for (int i = 0; i < n; i++) {
        printf("%d\t%s\t%d\n", i + 1, students[i].name, students[i].score);
    }
}

该算法首先输入学生姓名和分数，然后使用冒泡排序按照分数从高到低排序，最后输出排名。
