What language is Fedora written in?
 

I'm just beggining my journey into the world of programming and would like to know what language Fedora is written in.

Many.
But you could, should, would start with the following:
1. Python
2. Bash scripting

Fedora is a distro, which means it contains many programs written in many languages ...
If you mean the Linux kernel, that would be 'C'.
Most of the lower level / heavy duty stuff would be C/C++, some Assembler for Device Drivers, bash+python for scripting.
Many other langs are avail/used...

Does that help?
