只能说几乎等价

operator 是重载了运算符

而cmp就是一个函数

@[TLEWA](/user/515129) operator是不是搞了类似优先队列的东西

你试试把那个cmp丢给priority_queue set一类的，它们就不认cmp

@[bye_wjx](/user/575994) priority_queue和set不是可以```<int,vector<int>,greater<int> >```吗？

@[William_wyx](/user/320470) 举个例子，可以这样
```
struct wyx{
int x,y,t;
}b[100010];
bool operator <(wyx a,wyx b){
return a.t<b.t;
}
wyx a,b;
int main() {
cout << a<b;
}
```

@[TLEWA](/user/515129) 所以这个程序会输出1？
by William_wyx @ 2022-09-27 21:37:22
@[William_wyx](/user/320470) 而且可以定义更多奇怪的运算，比如矩阵乘法重载成乘号
