Quote: "It will be included in the exe right?"
Everything in the original input source code will in the resulting exe, but not in source form.

The compiler translates your input source code into machine code. Even though the original source code doesn't exist in the output exe,it's still possible to disassemble (and/or) decompile this back into something an experienced programmer could decipher the original programs logic from, but to be honest, nobody is going to bother.
