1. Set up your compose key on linux(Top right corner settings->system settings->keyboards->shortcut->typing->Compose key(choose an appropriate one)).
2. Whenever you need to type breaking space instead type (compose key + spacebar + spacebar). This puts a non-breaking space there instead. That's it.
3. Create file -> sudo nano hello(compose key + spacebar + spacebar)world.c
4. Paste the code to execute.
5. Makefile-> hello(compose key + space + space)world:
6. make
7. ./hello world (pressing tab will recognise the executable automatically).
NOTE: Don't do this ever in any production code or just ever. This hack can take up hours to resolve and a lot of frustration which could have better been spent on fixing something meaningful. This is a frowned upon practice. The only cool part is that your directory can have two files with whose name look exactly the same.
