定义职工工资结构体类型定义某车间职工工资结构体数组。编写四个函数分别用于： ①输入全车间职工的工号、姓名、基本工资、岗位工资、医疗住房基金与税金。 ②计算每一个职工实发工资，计算公式：实发工资=基本工资+岗位工资-医疗住房基金-税金。 ③按实发工资降序排序。 ④输出全车间职工的工号、姓名、基本工资、岗位工资、医疗住房基金、税金与实发工资。

以下是我为您准备的答案：

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

#define MAX_WORKERS 100

typedef struct {
    int id;
    char name[20];
    float base_salary;
    float position_salary;
    float medical_fund;
    float housing_fund;
    float tax;
    float real_salary;
} Worker;

Worker workers[MAX_WORKERS];
int num_workers = 0;

void input_workers() {
    printf("请输入职工信息：\n");
    printf("工号 姓名 基本工资 岗位工资 医疗基金 住房基金 税金\n");
    while (1) {
        Worker worker;
        scanf("%d", &worker.id);
        if (worker.id == -1) {
            break;
        }
        scanf("%s%f%f%f%f%f", worker.name, &worker.base_salary, &worker.position_salary, &worker.medical_fund, &worker.housing_fund, &worker.tax);
        workers[num_workers++] = worker;
    }
}

void calculate_real_salary() {
    for (int i = 0; i < num_workers; i++) {
        Worker *worker = &workers[i];
        worker->real_salary = worker->base_salary + worker->position_salary - worker->medical_fund - worker->housing_fund - worker->tax;
    }
}

int compare_workers(const void *a, const void *b) {
    Worker *worker1 = (Worker *)a;
    Worker *worker2 = (Worker *)b;
    if (worker1->real_salary < worker2->real_salary) {
        return 1;
    } else if (worker1->real_salary > worker2->real_salary) {
        return -1;
    } else {
        return 0;
    }
}

void sort_workers() {
    qsort(workers, num_workers, sizeof(Worker), compare_workers);
}

void output_workers() {
    printf("工号\t姓名\t基本工资\t岗位工资\t医疗基金\t住房基金\t税金\t实发工资\n");
    for (int i = 0; i < num_workers; i++) {
        Worker *worker = &workers[i];
        printf("%d\t%s\t%.2f\t%.2f\t%.2f\t%.2f\t%.2f\t%.2f\n", worker->id, worker->name, worker->base_salary, worker->position_salary, worker->medical_fund, worker->housing_fund, worker->tax, worker->real_salary);
    }
}

int main() {
    input_workers();
    calculate_real_salary();
    sort_workers();
    output_workers();
    return 0;
}

希望这个程序能够满足您的需求！
