Thread: [Dev-C++] XOR

XOR is this character: ^. It does not seem to operate in DevC++. When I
attempt to compile this:

#include <iostream>
using namespace std;
#define PI 3.14159
#define NEWLINE '\n'
int main ()
{
    char a;
    char b;
    cout << a ^ b << endl;
    system("pause");
}

I get this error:

invalid operands of types `char' and `<unknown type>' to binary `operator<<'


Is there a solution to this?

Heedle.

The language works you know, it's been around a bit!

You need to put a^b in parentheses because of operator precedence.

int main()
{
     char a = 'A';
     char b = 'Z';
     cout << static_cast<char>(a ^ b) << endl;
     system("pause");
 }

Omit the cast if you want the output as a number rather than a
character. This is because the default type of any expression
involving chars is actually int.
