The Pascal Triangle is a well-known number pattern in mathematics. Because of the way it is created, it is helpful to practice loops and strings. Let’s see how to implement the Pascal Triangle in Python. In this case, we can practice loops by creating each row of the triangle. We can also practice strings because […]

Abstraction is one of the most important concepts in programming. It is hard to write quality code in a programming language without a deep understanding of this concept. Abstraction is: “the purposeful suppression or hiding of some detail of a process or artifact in order to bring out more clearly other aspects details or structure”

One of the most asked computing-related questions is: What are the differences between Computer Science, Information Systems and Information Technology? The main differences are as follows: Computer Science (CS) focuses on Theory, Principles and Innovation on Application Technologies, Software Methods and Technologies, Systems Infrastructure. The practical component is low. Information Systems (IS) focuses on Application,
Pointers are a powerful tool available when you are programming in C/C++. As usual, we must be careful with the power we have. Let’s see the main problems we can face when working with pointers. There two main problems programmers face when working with pointers in C/C++: null references and garbage. C and C++ compilers
