General Knowledge Lab

1 Introduction

In this course, a lab activity can be either a hands-on (when you create a couple of programs) or a theoretical one (when you need to answer questions about programming topics that are very important you to know).

This lab will be a theoretical lab since we have discuss lots of initial concepts about programming without really showing much how to program yet.

You can either print this document and answer the questions below on the printed copy, or you can write the questions in a sheet of paper and answer them there. This is not a test! However, the kind of questions herein can easily be part of your 1^st exam, so be sure to discuss your answers with others classmates and the Lab-TA.You can look at any reference: my power point lectures, video lectures, and text book.

Take this opportunity to introduce yourself to a couple of classmates that are taking the lab with you and you have my permission to discuss your answers with them.

Do not write a “long poem” for each answer. At most 3 lines of text, please.
