Can't execute i386 binary file

[ghost]

• Your Windows build number:

10.0.15063

• What you're doing and what's happening:

I try to run i386 file in BashOnWindows.
I wrote a simple C program 'A.c' and use 'gcc A.c -m32' to make the file 'a.out'
When I use './a.out' to execute it.
It shows ''bash: ./a.out: cannot execute binary file:"

I use Google to find the solution for Ubuntu and try them.
When I use 'dpkg --print-foreign-architectures' to check out.
It shows 'i386' which means the system support i386 binary file.
But when I use './a.out', it still shows ''bash: ./a.out: cannot execute binary file:"

• What's wrong / what should be happening instead:

I am a rookie, and I don't know what is wrong.

WSL supports only 64-bit (you can consider upvoting the thread about 32-bit support on User Voice) so it will only work without -m32.

The output of dpkg --print-foreign-architectures just tells you that the package manager supports managing packages of those architecture (e.g. for cross-compiling), not that you can actually execute code targeted at them.
