with what language can I write binary code?
Please give me the answer quickly!
Whitespace, https://en.wikipedia.org/wiki/Whitespace_(programming_language), might be the closest you can get. Typically, programming in binary is not a good idea though, because it is much more efficient to use other languages.
To clarify, whitespace uses tabs and spaces as 0s and 1s.
Programming in binary is way harder than you think it is. You can TRY to program using HXD, it WILL NOT COME OUT WELL.
Binary is a number system, not a programming language. However, binary is the basic compilation of programs to run in the processors of computers using logic gates, normally with transistors (1=true/on, 0=false/off). By binary, I assume you mean machine code. Normally, machine code is written in hexadecimal instead of binary though. However, it is possible to do in binary. However, it is not recommended to program in raw machine code and something like Assembly or even C/C++ should better suit your needs, especially since machine code has no easy-to-use error messages, is not human-readable, and is platform-specific (ELF64 is different than ELF32 which is different than Win64 and Win32, for example).
If you have a TI-84 series calculator, you can program and compile assembly, there's no IDE, still. That's how I learned assembly.
Yeah, it is pretty nice. You have so much control.
And when you are done, you get a feeling of satisfaction largely unmatched with 3rd gen languages (Java), because when your done you've created a intricate tapestry of a program, with care and though given to every aspect for the most part.
Its not practical for most things, but it is fun.
