Alejandro If you’re planning to increase your computer science knowledge, understanding how to learn C++ programming language is a must. C++ has a reputation for being pretty tricky to master from scratch. For many people, this reputation alone can be off-putting. However, if you’re serious about computer science, spending some time mastering C++ is well worth it.
Despite being developed back in 1979, C++ is still used for building complex applications and large systems. In fact, the use of C++ continues to grow each year. In 2022, the program won the title of programming language of the year due to its rise in popularity. So, this is definitely a programming language that you need in your knowledge base.
Getting Started with C++ Programming
Before you do anything else, it’s helpful to understand the tools and software you’re going to need to use when learning C++.
Tools and Software
When it comes to getting equipped for mastering C++, you have a couple of options. First up, you can get the tools and software separately. You will need:
- Text editor – this is where you’ll write your code. Examples include Notepad++ and Atom.
- C++ compiler – the compiler checks your source code is correct and translates it into object files. Examples include Clang and GCC.
- Linker – the linker combines your object files together into one program and then links library files to it. Finally, it flags up any referencing issues.
- Libraries – most C++ programmers use the Standard C++ Library – this is a ready-made bunch of code you can use.
Alternatively, instead of these separate elements, you could use an IDE. An IDE or Integrated Development Environment features a text editor, C++ compiler, linker, and libraries all in one place.
Understanding C++ Programming Language and Syntax
After getting familiar with the tools you will need, it’s helpful to explore the syntax and terminology used in C++. Flexibility is one of the main advantages of using C++. But this freedom does make it easy to make mistakes and end up with a code full of bugs.
Keywords
Keywords are used to identify the variables, objects, and actions you include in your code.
Variables
Variables are essentially containers used to store data values.
Data Types
Data types tell variables what data to store. There are three main data types:
- Primitive
- Derived
- User-defined
Functions
Functions are blocks of code initiated to perform an action.
Syntax
Understanding C++ syntax will lay the foundation for your learning. This is especially helpful when learning this object-oriented programming language from scratch.
Syntax refers to the rules you will follow when writing C++ code.
Further Learning
There are some excellent online courses available to help you master C++ programming as a beginner. These include:
Final Thoughts
You’ll find C++ used in a huge range of industries, including aerospace, car manufacturing, and even the Google engine uses C++, so it’s not going anywhere anytime soon.
C++ may not be the simplest programming language to learn, but this knowledge will serve you well in any computer-science related role.
