A) Write and execute “Hei maailma” (Hello world) in three languages. Install necessary environments.
First, i decided to try C. I found a C “Hello world” example here.
I ran following commands:
I installed gcc to compile C, created a folder for my various “Hei maailma”-programs, changed location to the newly created folder and launched nano to write my first program.
In nano i wrote the program:

Finally i tried perl, which also was installed by default on xubuntu. I found a “Hello world” tutorial here:
I ran the program:
“Hello world” on perl was also fairly effortless to write and execute, but contain more code compared to python3’s one line.
