    for (int x = 0;x<=255;x++){
        cout<< sbox[x]^ sbox[x]<<endl;



    }
    return 0;

}

我收到一条错误消息:

[Error] invalid operands of types ‘const long unsigned int’ and
‘<unresolved overloaded function type>’ to binary ‘operator<<’".

我的代码有什么问题？

Answer 1

操作顺序:<<高于^ .

在 sbox[x]^ sbox[x] 两边加上括号:

 cout << (sbox[x]^sbox[x]) << endl;
