Introduction to C++
Before we commence coding, let’s invest a few moments discussing C++. C++ stands among the most favored programming languages globally and serves as the preferred language for constructing performance-critical applications. It is employed by prominent entities like Adobe, Google, Microsoft, Netflix, and even governmental bodies such as NASA. C++ boasts the advantage of being one of the swiftest and most efficient languages, making it an excellent choice for applications necessitating speed and memory efficiency.
The Two Elements You Must Grasp
To achieve mastery in C++, two essential components must be grasped. First and foremost is the C++ language itself, encompassing the syntax or grammar of the language. The second crucial aspect is the C++ Standard Library (STL). The STL constitutes a compilation of pre-existing C++ code offering functionalities essential to many applications. These functionalities include data structures like lists and maps, along with algorithms for searching and sorting data.
Given that these functions are requisite in nearly every application, utilizing some of the C++ code from this library enables the swift development of applications without building all the functionality from scratch each time. While this course delves into major functionalities in the standard library, it’s imperative to note that the standard library is vast, and we’ll only scratch the surface here. For those eager to delve deeper, there are dedicated books on this subject.
Learning C++ Incrementally
Many individuals find C++ somewhat extensive and daunting. However, the reality is that you don’t need to learn the entirety of C++ to craft substantial programs. Similar to not needing to comprehend every feature your TV offers to use and enjoy it, you needn’t learn every single feature of C++ to commence developing useful programs.
Throughout this course, we will explore C++ incrementally, gradually progressing from foundational principles to more advanced concepts. As you engage with C++, numerous exercises will be provided to facilitate a better understanding and retention of the concepts. Subsequently, you’ll realize that C++ isn’t as formidable as it may initially seem. If you follow the course, you’ll attain the capability to write C++ code confidently by its conclusion.
The Tools You Require
In crafting C++ programs, an Integrated Development Environment (IDE) is employed. An IDE is an application encompassing an editor for code composition, in addition to building and debugging tools. Numerous IDEs, both free and commercial, are available. The top three C++ IDEs comprise Microsoft Visual Studio, Xcode, and CLion.
While this course employs CLion, you don’t need to use it; any tool of your preference suffices. The focus here isn’t on the tooling but on the C++ language itself. If you’re an absolute beginner with no prior coding experience, it’s recommended to download the free version of CLion for easy participation. Subsequently, you can either obtain a license or explore one of the free alternatives. Visit jetbrains.com/clion/download to download CLion compatible with your operating system. After installation, we can proceed with the course.
Creating Your Inaugural C++ Program
Now equipped with the necessary tools, let’s collaboratively create our first C++ program. Upon launching CLion initially, you may be prompted to activate your license. For now, select “Start Trial” to proceed. You’ll need to establish or log into your JetBrains account and then commence your trial. On the welcome screen, select “New Project” to initiate a new C++ project. Specify the project’s location and choose the C++ language standard – in this instance, we’ll opt for version 20. After project creation, you’ll observe a file named “main. cpp” in the project window, serving as our program’s main file. Subsequently, we can proceed to write our code in this file.
Your Initial C++ Program
Let’s commence with a metaphor. Consider your TV; it features various functions like channel changing and volume control. Analogously, a C++ program comprises tens, hundreds, or thousands of functions, each serving a distinct purpose. In C++, a particular function, “main,” holds significance as the entry point to our program – akin to the power button on a TV.
Upon executing our program, the operating system (e.g., Windows or macOS) invokes this function to initiate our program. The main function is required to return a value of type “int,” indicating whether our program terminated successfully. In this instance, our program will simply print “Hello, World” on the screen and return the value of zero to signify a successful termination. Let’s draft the code for our inaugural C++ program:
std::cout << “Hello, World” << std::endl;
Having crafted our code, the subsequent steps involve compilation and execution. To execute the program, click the play icon on the toolbar or employ the shortcut Ctrl+R (Command+R on Mac). This process compiles our code into machine code executable by the computer’s operating system. Once compiled and executed, the output will manifest in the console or terminal window, displaying “Hello, World.” Congratulations! You’ve successfully created your initial C++ program.
Conclusion: Coding Tutorials C++
This marks the conclusion of the initial section of the Coding Tutorials C++ blog. Throughout this section, we delved into C++ fundamentals, encompassing variables, constants, mathematical expressions, console input and output, comments, and utilization of the standard library. Additionally, we created our debut C++ program and acquired insights into compilation and execution. In the subsequent section, we will delve deeper into C++ and explore more intermediate-level concepts. Stay tuned!
