c语言程序设计职工考勤系统代码

以下是一个简单的职工考勤系统的 C 语言程序设计代码，仅供参考：

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

#define MAX_EMPLOYEES 100

typedef struct {
    char name[50];
    int hours_worked;
    float wage;
} Employee;

void add_employee(Employee employees[], int *num_employees) {
    if (*num_employees == MAX_EMPLOYEES) {
        printf("Max employees reached.\n");
        return;
    }

    Employee new_employee;
    printf("Enter employee name: ");
    scanf("%s", new_employee.name);
    printf("Enter hours worked: ");
    scanf("%d", &new_employee.hours_worked);
    printf("Enter wage: ");
    scanf("%f", &new_employee.wage);

    employees[*num_employees] = new_employee;
    (*num_employees)++;
}

void print_employees(Employee employees[], int num_employees) {
    printf("%-20s%-20s%-20s\n", "Name", "Hours Worked", "Wage");

    for (int i = 0; i < num_employees; i++) {
        printf("%-20s%-20d%-20.2f\n", employees[i].name, employees[i].hours_worked, employees[i].wage);
    }
}

float calculate_pay(Employee employee) {
    float pay = employee.hours_worked * employee.wage;
    if (employee.hours_worked > 40) {
        pay += (employee.hours_worked - 40) * employee.wage * 0.5;
    }
    return pay;
}

void print_payroll(Employee employees[], int num_employees) {
    printf("%-20s%-20s\n", "Name", "Pay");

    for (int i = 0; i < num_employees; i++) {
        printf("%-20s%-20.2f\n", employees[i].name, calculate_pay(employees[i]));
    }
}

int main() {
    Employee employees[MAX_EMPLOYEES];
    int num_employees = 0;

    int choice;
    do {
        printf("\n1. Add employee\n");
        printf("2. Print employees\n");
        printf("3. Print payroll\n");
        printf("4. Quit\n");
        printf("Enter choice: ");
        scanf("%d", &choice);

        switch (choice) {
            case 1:
                add_employee(employees, &num_employees);
                break;
            case 2:
                print_employees(employees, num_employees);
                break;
            case 3:
                print_payroll(employees, num_employees);
                break;
            case 4:
                printf("Goodbye.\n");
                break;
            default:
                printf("Invalid choice.\n");
                break;
        }
    } while (choice != 4);

    return 0;
}

该程序使用结构体存储每个员工的姓名、工作时间和时薪等信息，并提供添加员工、打印员工列表和计算工资单等功能。
