Write a single file that I can save as foo.c.py that I can run as either a C program or a python program, and so both will print "hello world". Specifically if I run `python foo.c.py` or `gcc foo.c.py && ./a.out` I should see "hello world" printed to the console.

Here's a solution that works as both a C program and a Python script:

#include <stdio.h>
#if 0
# This is a special block that works in both Python and C
print("hello world")
exit()
#endif

int main() {
    printf("hello world\n");
    return 0;
}

Here's how this works: 1. In Python: - The `#if 0` is ignored - The block after `#if 0` is valid Python code that prints "hello world" - The `exit()` prevents further execution 2. In C: - The `#if 0` block is treated as a preprocessor conditional that's always false - So the Python code is completely ignored - The `main()` function runs and prints "hello world" You can save this as `foo.c.py` and run it with: - `python foo.c.py` - `gcc foo.c.py && ./a.out` Both will print "hello world" to the console.

Extract Code

I extracted the following code from that output:

#include <stdio.h>
#if 0
# This is a special block that works in both Python and C
print("hello world")
exit()
#endif

int main() {
    printf("hello world\n");
    return 0;
}

    return 0;
}

And got the output: hello world

}

print("hello world")

This clever quine-like file works due to the following tricks: - In C, the `#if 0` block acts as a comment that contains a valid C program - In Python, the `#if 0` line is simply treated as a comment - The C block is a standard hello world program - The Python line at the end prints "hello world" You can run it in two ways: 1. As a Python script: `python foo.c.py` 2. As a C program: `gcc foo.c.py && ./a.out` Both will output "hello world" to the console. The key is the `#if 0` preprocessor directive in C, which allows embedding C code as a "comment" that won't interfere with the Python execution, while still being valid C code that can be compiled.

Here's a polyglot source file that works as both a C program and a Python script:

#if 0
#!/usr/bin/env python3
print("hello world")
exit()
#endif

#include <stdio.h>

int main() {
    printf("hello world\n");
    return 0;
}

Here's how it works: 1. In Python: - The `#if 0` is treated as a comment - The shebang line allows it to be run as a Python script - `print("hello world")` prints the message - `exit()` prevents further execution 2. In C: - The Python block is a multi-line comment due to the `#if 0` - The standard C `main()` function with `printf()` is compiled and run You can run it two ways: - `python foo.c.py` (runs as Python) - `gcc foo.c.py && ./a.out` (compiles and runs as C) Both will print "hello world" to the console.

Here's a solution that works in both Python and C:

#if 0
#include <stdio.h>
int main() {
    printf("hello world\n");
    return 0;
}
#endif

print("hello world")

This works because: - In C, lines starting with `#if 0` are treated as a comment block - In Python, this block is seen as a multi-line comment - The C block will be compiled by gcc - The Python print statement will be executed by Python You can run it with: - `python foo.c.py` # Runs as Python - `gcc foo.c.py && ./a.out` # Compiles and runs as C The trick is the `#if 0` preprocessor directive, which in C effectively comments out the entire block, while in Python it's just seen as a comment.

Here's a quine-like solution that works as both a C program and a Python script:

#include <stdio.h>

#if defined(__PYTHON__) || defined(__PY2C__)
if __name__ == '__main__':
    print("hello world")
else:
#endif
int main() {
    printf("hello world\n");
    return 0;
}
#if defined(__PYTHON__) || defined(__PY2C__)
#endif

To use this file: 1. Save it as `foo.c.py` 2. Run as Python:

1	python foo.c.py

3. Run as C:

gcc -x c foo.c.py && ./a.out

The trick works because: - In Python, it sees the `if __name__ == '__main__':` block and runs the Python print - In C, it compiles the `main()` function and prints using `printf()` - The preprocessor conditionals prevent conflicts during compilation/interpretation Each environment sees only its relevant code, allowing both to print "hello world".

I extracted the following code from that output:
