Top 5 Source Codes of the Common Exercises in C++

How to Learn C++ and What Makes It Different with C Programming Language?

I am going to show you how to nail those C++ programming common problems that you are encountering in every programming language exercises. I found these files in my old storage, so I will be sharing these C++ programming solutions to those who are eager to learn more about C++ or C programming. Sometimes, some of these exercises are used in laboratory exams or quizzes. Hence, it is way better to learn the strategies of these top 5 programming problems in C++ first and I guarantee you that the other high end programming languages will be easy for you to understand.

On the other hand, what makes C++ different with C programming language? And, can you use these C++ codes in C programming? C++ and C programming are almost the same, however, these 2 programming languages have evolved over time. C++ is actually the superset of C programming. C++ is a multi-paradigm programming language which is procedural and object oriented, unlike C programming which is only procedural. Thus, C++ can run almost all of C programming syntax while C has problems with C++ codes and you might be having difficulties in converting it. Moreover, you can use these codes that I will show you in C programming, but you should bear in mind that you have to change some of the correct syntax in the program. Furthermore, if you are a loyal C programmer then I suggest that you should make yourself comfortable with C++ as well because it has a lot of advancements than C.

My Source Code for the Top 5 Common Problems in C++ Programming

I am an avid fan of C++. First is, I like how it looks and how your creative mind runs when you create a simple animation out of the plain colorful pixelated shapes. Unlike some of the high-end programming languages with awesome GUI, you have to create your own looping codes and timer codes in C++ in order for you to create your own animation which is a lot of fun for me. It challenges my imagination. Second is, this is the first programming language that I have encountered and learned. Third is, I like the C++ syntax, maybe because this is the first programming language I have encountered and I am very comfortable with it. I like how to start and end the functions with braces. Thus, I like the simplicity of the looping technicalities and structure of C++ than the other programming languages. Furthermore, when I encountered Java, it became one of my favorite programming languages as well because it has similarities with the C++ structure. Programming in C++ is fun and you should try to learn c++ programming.
