设计person类，包括私有数据成员：姓名；设计student类继承person类，新增私有数据成员：班级；设计类worker继承person类，新增私有数据成员：职业；设计类studentworker继承student类和worker类，新增私有数据成员：工资；在主函数中定义一个studentworker类的对象，调用该对象的show函数输出该对象的信息。

以下是使用C++编写的代码实现：

#include <iostream>
#include <string>
using namespace std;

class Person {
private:
    string name;

public:
    Person(string n) : name(n) {}

    void setName(string n) { name = n; }
    string getName() const { return name; }
};

class Student : public Person {
private:
    string className;

public:
    Student(string n, string c) : Person(n), className(c) {}

    void setClassName(string c) { className = c; }
    string getClassName() const { return className; }
};

class Worker : public Person {
private:
    string job;

public:
    Worker(string n, string j) : Person(n), job(j) {}

    void setJob(string j) { job = j; }
    string getJob() const { return job; }
};

class StudentWorker : public Student, public Worker {
private:
    double salary;

public:
    StudentWorker(string n, string c, string j, double s) : Student(n, c), Worker(n, j), salary(s) {}

    void setSalary(double s) { salary = s; }
    double getSalary() const { return salary; }

    void show() const {
        cout << "Name: " << getName() << endl;
        cout << "Class: " << getClassName() << endl;
        cout << "Job: " << getJob() << endl;
        cout << "Salary: " << salary << endl;
    }
};

int main() {
    StudentWorker sw("Tom", "ClassA", "Engineer", 5000.0);
    sw.show();

    return 0;
}

在主函数中创建了一个名为sw的StudentWorker对象，其构造函数分别传入了姓名、班级、职业和工资信息。调用了sw对象的show函数输出了该对象的信息。输出结果如下：

Name: Tom
Class: ClassA
Job: Engineer
Salary: 5000
