如何将typedef结构复制到另一个结构中？

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

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

typedef struct {
    int id;
    char name[20];
    float salary;
    char department[20];
} EmployeeExtended;

void copyStruct(Employee* dest, const Employee* src) {
    dest->id = src->id;
    strcpy(dest->name, src->name);
    dest->salary = src->salary;
}

int main() {
    Employee employee1 = { 1, "John Doe", 5000.0 };
    EmployeeExtended employee2;

    copyStruct((Employee*)&employee2, &employee1);
    strcpy(employee2.department, "IT");

    printf("Employee 1: %d, %s, %.2f\n", employee1.id, employee1.name, employee1.salary);
    printf("Employee 2: %d, %s, %.2f, %s\n", employee2.id, employee2.name, employee2.salary, employee2.department);

    return 0;
}
