How to run the application?

[Idol11112222]

For now, I have installed wsl to mimic Ubuntu on my windows operating system. I'm trying to open a fractals3d-linux file with sh fractals3d-linux but it says: fractals3d-linux: line 1: : not found
fractals3d-linux: line 1: ELF : not found
fractals3d-linux: line 13: syntax error: unexpected "("
also I wrote git clone https://github.com/Constantor/fractals3d/ got the source code and trying to run sh main.cpp in fractals3d root folder got the following: main.cpp: 4: Syntax error: "(" unexpected
Help!
