Regardless of how good a programmer you are, you will encounter many types of programming errors in your code. Errors appear at different stages in the program implementation phase. To a novice programmer, it is important for you to be able to read and understand these error messages so that you will be able to … Read more
Programming operators are symbols that tell a compiler what mathematical or logical manipulation is to be performed on the data entered. In programming, as in mathematics, there are many operations that may be performed. However, the operators used in mathematics are not all the same as those used in programming. In this article, we will … Read more
As with any other programming language, Pascal variables are meant to hold data of different types that are expected to change while the program is being run. The types of variables used in Pascal programs are char, string, integer, real and boolean. To initialize a variable, we write the variable name followed by a colon … Read more
There are many different computer programming languages. However, if you are new to programming, Pascal is an ideal programming language for a beginner. In this article, we will address: What is Pascal Pascal is a high-level procedural programming language. For those of you who do not know what this means, high-level languages (HLL) are machine-independent, … Read more

In this article, we will explore what an algorithm is. However, before exploring algorithms in information technology, we also need to look at the problem defining diagram. The IPO or problem defining diagram is a tool the Caribbean Examination Council uses in problem definition stage of the problem solving process. It is a simple table … Read more
This article on programming fundamentals seeks to introduce the idea of variables and consonants. We explain what these concepts mean and when to use each in a computer program. Variables and consonants contain values that are used in calculations. However, each of these has a different use, and understanding this will help us to know … Read more
A calculated field in Access Query is used to generate new information. It does not affect the information already in the table. Instead, it allows the user to generate additional information by doing calculations. For instance, what if you had a database table containing the date of birth of all the students in a school, … Read more
