C语言用结构体数组输入工号，姓名，工资，并且降序排序输出

以下是C语言代码：

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

struct Employee {
    int id;
    char name[20];
    float salary;
};

int main() {
    int n;
    printf("Enter the number of employees: ");
    scanf("%d", &n);

    struct Employee employees[n];

    for (int i = 0; i < n; i++) {
        printf("Enter employee %d details:\n", i+1);
        printf("ID: ");
        scanf("%d", &employees[i].id);
        printf("Name: ");
        scanf("%s", employees[i].name);
        printf("Salary: ");
        scanf("%f", &employees[i].salary);
    }

    // sort employees in descending order of salary using bubble sort
    for (int i = 0; i < n-1; i++) {
        for (int j = 0; j < n-i-1; j++) {
            if (employees[j].salary < employees[j+1].salary) {
                struct Employee temp = employees[j];
                employees[j] = employees[j+1];
                employees[j+1] = temp;
            }
        }
    }

    printf("\nEmployees sorted in descending order of salary:\n");
    printf("ID\tName\tSalary\n");
    for (int i = 0; i < n; i++) {
        printf("%d\t%s\t%.2f\n", employees[i].id, employees[i].name, employees[i].salary);
    }

    return 0;
}

该程序首先提示用户输入员工数量，然后使用结构体数组存储每个员工的工号、姓名和工资。然后，它使用冒泡排序将员工按照工资的降序排序。最后，程序输出排序后的员工列表。
