Since 2000, I have given a high school presentation called, The Value of An Education.
During this four day event I spend two days on programming using 1986 MS QBASIC. Why? No GUI and I have twenty minutes before the students are lost and looking out the window.
Guess a number between 1-100, is less than 8 lines of code...no GUI
Calculate interest on saving account is 14 lines

*** CMD/ Qbasic no longer runs on win 7,8,or 10...

Python basic ?

Please add your ideas
Thanks
