多种处理字符串涵数:

 

 

=========================================

异质

class Vehicle
{
public:
    virtual void run() const = 0;
};

// 派生于Vehicle的具体类Car
class Car: public Vehicle
{
public:
    virtual void run() const
    {
        std::cout << "run a car\n";
    }
};

// 派生于Vehicle的具体类Airplane
class Airplane: public Vehicle
{
public:
    virtual void run() const
    {
        std::cout << "run a airplane\n";
    }
};
void run_vehicles(const std::vector& vehicles)
{
    for (unsigned int i = 0; i < vehicles.size(); ++i)
    {
        vehicles[i]->run();     // 根据具体vehicle的类型调用对应的run()
    }
}

int main()
{
    Car car;
    Airplane airplane;
    std::vector v;    // 异质vehicles集合
    v.push_back(&car);
    v.push_back(&airplane);
    run_vehicles(v);            // run不同类型的vehicles
}
