强烈支持楼主ing…… 好资料 #include <iostream>
#include <string>
class Company
{
public:
Company(std::string theName, std::string product);
virtual void printInfo();
protected:
std::string name;
std::string product;
};
class TechCompany : public Company
{
public:
TechCompany(std::string theName, std::string product);
virtual void printInfo();
};
Company::Company(std::string theName, std::string product)
{
name = theName;
this->product = product;
}
void Company::printInfo()
{
std::cout << "这个公司的名字叫：" << name <<
"正在生产" << product << "\n";
}
TechCompany::TechCompany(std::string theName, std::string product) : Company(theName, product)
{
}
void TechCompany::printInfo()
{
std::cout << name << "公司大量生产了 " << product << "这款产品!\n";
}
int main()
{
Company *company = new TechCompany("APPLE", "Iphone");
TechCompany *tecCompany = (TechCompany *)company;
tecCompany->printInfo();
delete company;//只要删除company或者tecCompany这个指针因为它们两个是同一个地址不能重复释放
delete tecCompany;
company = NULL;
tecCompany = NULL;
return 0;
}
