Well done folks! We have finally arrived. This the third part of the three-part computer programming post. We will learn how to write a program that will accept data by user input through the keyboard and also print out a result to the computer monitor after performing a simple task of checking if the number is positive of negative. For simplicity, I have chosen the object-oriented, higher level programming language C++ to program the computer to perform a simple computation for us. We will write a C++ program that will prompt the user to type in an integer and the program will check whether the entered integer is positive or negative and display an appropriate output. //////////////////////// #include <iostream> using namespace std; int main() { /*variable declarations*/ int number; int threshold = 0; // we assume 0 is positive /*user prompted for input, then input received from keyboard*/ cout<<... read more

This is the second part of the Computer Programming three part blog post. Here is a synopsis of the background knowledge and the necessary terminology needed before writing a computer program. Those students who are curious about writing computer programs, those who are being home-schooled, or those who are in special education programs will find this post especially useful. I intend to prepare you to speak the language of computer programmers. This will also prepare you for the computer programming that we will engage in my next blog post of this series. If you have already written a computer program you will get a review of the basics as well as get a better understanding of what happens behind the scenes. On a humorous note, we are not talking about the sage on the stage, but the guide on the side.   Introduction to Computer Programming Terminology: 1. A programming language is a formal constructed language designed to communicate instructions to a computer or a... read more

Some of us come with a knack to program computers and with little effort we can get the computer to work for us. On the other hand, some of us don't have a clue how to even get started. We may dread the errors that computer programs give such as "Compile error", or "undefined variable" or we may just be indifferent to anything computer programming related.   I will attempt to unpack the knowledge that has intrigued some of you into simpler and more understandable concepts. Let me start by stating that this series of blog posts is by no means a complete course on how to program a computer. However, I will give you the basics that you need to create simple computer programs. I will also give it to you in easy digestible pieces so it will not be too overwhelming. This way you can impress yourself and others with your newfound knowledge.   So you may ask yourself the question: "How do we bridge the knowledge gap?" I agree. Computers... read more

I find that many students have a fear of math. One reason for this fear is that math continues to builds on itself. For example, if you have difficulty w Algebra 1, chances are unless you go back and relearn it, you will continue to struggle w Algebra 2, pre calc, etc.  I realized this as I would start tutoring a student in more advanced classes, but they never understood the PEMDAS concept from Elementary school.   Most schools nowadays, tend to push the kids through to higher in order to raise their ratings. My feeling is that if a child is struggling in Algebra 1 as an 8th grader, they should consider retaking the course in 9th grade. It will give them a confidence boost in math and help their GPA too. If you push them ahead, it could turn out much worse later on. Since you need a solid foundation to build a skyscraper, you should not advance in math until you understand the basic concepts. Go back and relearn them and you will move forward w understanding and... read more

  When I started to learn English, I started to listen to many tapes so I could figure out the pronunciation. In order to pick up the rhythm, the melody and the tone of the language, you need to learn the common sounds of the new language. Understanding basic grammar In my adult head, I had to figure out the structure of the sentences to be able to express myself. How was this language built? Were there nouns? Genders? How was plural mentioned? Were there tenses for the verbs to express past, present and future? Beside the nouns, I recommend to learn the personal pronouns (I, you, he/she, we, they) and a few verbs at the present tense (to be, to have, to do, can, must). Add to this a few adjectives like “small”, “big”, “difficult”, “easy”, “tired”. And you’re good to go.
