Why I cannot cout the result?

I have this error message:

Error   C2678   binary '^': no operator found which takes a left-hand
 operand of type 'std::basic_ostream<char,std::char_traits<char>>' 
(or there is no acceptable conversion)

with this code:

#include <iostream>
#include <string>
using namespace std;
int main()
{
    cout << 2 ^ 4;
}

could you help me with this code, please

Can you use this code.

#include <iostream>
#include <string>
using namespace std;
int main()
{
    cout << (2 ^ 4);
    return 0;
}

operator<< has higher precedence than operator ^, so cout << 2 ^ 4; is interpreted as (cout << 2) ^ 4;. (cout << 2) returns cout itself, which can't be used as operand of operator ^.

Change the code to

cout << (2 ^ 4);
