使用冒泡排序对结构数组进行排序时出现警告

#include <stdio.h>

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

void bubbleSort(Student arr[], int n) {
    for (int i = 0; i < n-1; i++) {
        for (int j = 0; j < n-i-1; j++) {
            // 比较score成员，确保类型匹配
            if (arr[j].score > arr[j+1].score) {
                Student temp = arr[j];
                arr[j] = arr[j+1];
                arr[j+1] = temp;
            }
        }
    }
}

int main() {
    Student students[] = {{1, "Alice", 85.5}, {2, "Bob", 90.0}, {3, "Charlie", 78.5}};
    int n = sizeof(students) / sizeof(students[0]);

    bubbleSort(students, n);

    printf("Sorted list:\n");
    for (int i = 0; i < n; i++) {
        printf("ID: %d, Name: %s, Score: %.1f\n", students[i].id, students[i].name, students[i].score);
    }

    return 0;
}
