Control structures, conditions, or decision-making in Pascal are necessary to cater to different eventualities. These structures require the program to test and run different outcomes based on the results of those tests. In programming, decision-making is usually indicated by if-then-else or switch statements. In this lesson, we will explore two algorithms and Pascal programming examples … Read more
In recent years, wireless network technologies have replaced the older wired technologies as a way to connect computing devices. They are easier to connect to and use than their wired counterparts. They are also easier and less expensive to set up and use on the go. This makes them highly attractive to computer users on … Read more
If you have ever used a computer, there is a good chance that you have also used a network. Companies often use networks to share resources between computers easily. There are many different types of networks. In this article, we will explore: What is a network? A network is a group of computers that you … Read more
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
