Add comments to a Python script and make it a bilingual Python/C++ “program”

(Thx @Linus for the byte count)

(1 byte saved thx @Conor O'Brien) (1 byte saved thx @PieCot)

Counting bytes again by hand, I found 113. Maybe it's right this time. No it's not

#include <cstdio>
#define def main(){0?
#define print(x) puts(x);}
#define greet()

Notes: stdio and puts are still alive and kicking in C++. The missing int type is valid in C++ 4. Test

Prepend:

#include<cstdio>
#define print(A)main(){puts(A);}
#define greet()
#define \

The preprocessor backslash \ pulls the nasty : containing line into an unused macro. Try it here.

Thanks to edc65's answer for the note about implicit int in C++4.
Thanks to PieCot's answer for suggesting <cstdio> over <stdio.h>.
Thanks to Leon for suggest I remove the X in the original #define X\.

The lines to be prepended are:

#import <iostream>
#define def int main(){0?
#define greet()
#define print(A) 0;std::cout<<A"\n";}

And the resulting code:

#import <iostream>
#define def int main(){0?
#define greet()
#define print(A) 0;std::cout<<A"\n";}
def greet():
    print("Hello, world!")

greet()
