如何返回一个包含各种结构的一维结构函数的指针？

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

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

typedef struct {
    int id;
    char title[20];
    float salary;
} Job;

typedef struct {
    int id;
    int quantity;
    float price;
} Product;

void* createStructArray() {
    Employee* employees = (Employee*)malloc(3 * sizeof(Employee));
    for (int i = 0; i < 3; i++) {
        employees[i].id = i + 1;
        sprintf(employees[i].name, "Employee%d", i + 1);
    }
    return employees;
}

int main() {
    Employee* employees = (Employee*)createStructArray();
    for (int i = 0; i < 3; i++) {
        printf("Employee %d: ID=%d, Name=%s\n", i + 1, employees[i].id, employees[i].name);
    }
    free(employees); // 释放内存
    return 0;
}
