今天七夕,群友让我帮忙给他分配一个对象,于是我只好尝试给他分配对象了:
CGirlFrined *pGF = new CGirlFrined("大屌萌妹");
int nRet = (群友).SetGirlFriend(pGF);
if (nRet != 0)
{
alert("分配失败!");
}
后来觉得这段代码过于简单,分配的方法也有些过于简单了,于是我参考了网上的代码,然后丰富了代码内容,包含NTR在内的更多的分配方式:
#include <iostream>
#include <list>
using namespace std;
class CGirlFriend {
public:
string name;
int age;
CGirlFriend() {
this->name = "小萝莉";
this->age = 0;
}
CGirlFriend(const string& name, int age = 12)
: name(name), age(age)
{}
static void* operator new(size_t size){
cout << "女朋友准备中。。。" << endl;
return malloc(size);
}
static void* operator new(size_t size, CGirlFriend* ptr){
cout << "NTR别人的女朋友。。。" << endl;
return ptr;
}
static void* operator new[](size_t size) {
cout << "一大波女朋友准备中。。。" << endl;
return malloc(size);
}
static void* operator new[](size_t size, list<void*>& lt) {
cout << "女朋友们的聚会准备中。。。" << endl;
void* tmp = malloc(size);
lt.push_back(tmp);
return tmp;
}
};
int main(void)
{
CGirlFriend* gf1 = new CGirlFriend("小萝莉");
CGirlFriend* gf2 = new(gf1) CGirlFriend;
delete gf2;
CGirlFriend* gfs = new CGirlFriend[10]{ { "萌妹子", 19 } };
for (int i = 0; i < 10; ++i)
cout << (gfs + i)->name.c_str() << endl;
delete[] gfs;
list<void*> girlList;
CGirlFriend* gfss1 = new (girlList) CGirlFriend[10];
for (int i = 0; i < 10; ++i)
cout << (gfss1 + i)->name.c_str() << endl;
CGirlFriend* gfss2 = new (girlList) CGirlFriend[20];
for (auto& ptr : girlList)
delete[] ptr;
system("pause");
return 0;
}
此代码在vs2015上测试运行通过,结果如下:
欢迎交流与讨论。
