c++运算符重载

今天在快要下班的时候，突然有个要求说，关于设备信息的排序要使用通道号大小来排序，对于之前一直都是使用标题来默认排序的，那么就需要将这个通道的信息进行一个比较才能排序了，于是想到了要重载运算符> < =；由于时间比较紧，所以就随便写了一个运算符重载的函数，没想到搞了几分钟没编译过，吓的不轻，赶紧挂机回家算了，回到家中想想，其实方法是没错的，只是当时有些急着下班，所以就出错了，这个就当回顾一下吧！

#include
#include

typedef struct channel_info
{
int name;
int ip;
int title;
int devName;
void operator=(const channel_info& info)
{
this->name = info.name;
this->ip = info.ip;
this->title = info.title;
this->devName = info.devName;
}
bool operator>(const channel_info& info)
{
return (this->name > info.name &&
this->ip > info.ip &&
this->title > info.title &&
this->devName > info.devName);
}
bool operator<(const channel_info& info)
{
return (this->name < info.name &&
this->ip < info.ip &&
this->title < info.title &&
this->devName < info.devName);
}
bool operator==(const channel_info& info)
{
return (this->name == info.name &&
this->ip == info.ip &&
this->title == info.title &&
this->devName == info.devName);
}
}CHANNEL_INFO;
int main(int argc, char* argv[])
{
CHANNEL_INFO info;
info.name = 1;
info.ip = 2;
info.title = 3;

info2.name = 2;

info2.title = 4;
info2.devName = 5;
vector vct;
vct.push_back(info);

{
std::cout<<"infoTMP < info2, swap value!"<<std::endl;
//infoTmp = info2;
vct.at(1) = vct.at(2);

return 0;
}
