Java/C++ polyglot
Today I discovered Java’s “inline C++” keyword, //\u000a/*, which makes a Java/C++ polyglot pretty easy:
//\u000a/*
#include <iostream>
#define private
#define public
#define static
#define void int
struct {
std::ostream &println(const char *c) {
return std::cout << c < < std::endl;
}
} out;
//*/
/*\u002a/
import static java.lang.System.out;
public class Polyglot {
//*/
public static void main(/*\u002a/String[] args//*/
) {
out.println("Hello from whatever language this is!");
}
/*\u002a/
}
// */
Eclipse deals.. okay. The red-underlining in the commented sections is for the spelling. <3
