今天写c++，当我写出如下代码时，编译器报错了

#include<bits/stdc++.h>

using namespace std;

int main(){
    int a=1,b=3,c=2,d=6;
    // cout<<(a^b^c^d)<<endl;
    cout<<a^b^c^d<<endl;
    return 0;
}

D:\sublineText\demo\demo.cpp: In function 'int main()':
D:\sublineText\demo\demo.cpp:8:12: error: no match for 'operator^' (operand types are 'std::basic_ostream<char>' and 'int')
    8 |     cout<<a^b^c^d<<endl;
    

 

#include<bits/stdc++.h>

using namespace std;

int main(){
    int a=1,b=3,c=2,d=6;
    cout<<(a^b^c^d)<<endl;
    // cout<<a^b^c^d<<endl;
    return 0;
}

这样就对了，占个坑，现在不知道是怎么回事

文心一言的解释也很ex
