If you don't have a root login (probable, under a Ubuntu derivative like Mint) then you need to add 'sudo' in front of any commands you execute which need root privileges to run. i.e.:

% sudo apt-get remove pentium-builder

Use your regular password when it asks you for one.

Awesome! Good job.



It's hard for me to say, since I haven't seen the code. I imagine that it's just a text-mode command line program, so assuming that the executable you compiled to is in /home/David/Desktop, then yeah--the above should run it.

Double-clicking it is slightly more complicated; it will run the program but in most cases you won't see the output so you won't know that it's been run.



No--it's a Linux ELF executable file, which is not compatible with the Windows executable file format.



Books are an excellent idea. Also, Googling for "c++ tutorial" will get you lots of hits. One that looks pretty good is https://www.cplusplus.com/doc/tutorial/


Good luck!
