Introduction to CPP or C++

C++ is a general-purpose programming language that was created as an enhancement to the C language to include an object-oriented paradigm. It is both an imperative and a compiled language.

C++ is a middle-level language, which allows it to program low-level (drivers, kernels) and even higher-level applications (games, GUI, desktop apps, etc.). Both C and C++ have the same basic syntax and code structure.

The following are some of the features and key points to remember about the programming language:

1. Simple: It is a simple language in the sense that programs can be broken down into logical units and parts, that it has rich library support, and that it supports a wide range of data types.

2. Machine-independent but platform-dependent: A C++ executable is not platform-independent (compiled programs on Linux will not run on Windows), but it is machine-independent.

3. Mid-level language: It is a mid-level language because we can do both systems programming (drivers, kernels, networking, etc.) and large-scale user applications with it (Media Players, Photoshop, Game Engines, etc.)

4. Support from a large library: Has extensive library support (both standard built-in data structures, algorithms, and so on) as well as 3rd party libraries (e.g. Boost libraries) for fast and rapid development.


C++ Applications:

1. C++ is used in a variety of applications, including:

2. Systems & Operating Systems Programming, for example, Linux-based operating systems (Ubuntu, etc.)

3. Users of browsers (Chrome & Firefox)

4. Game engines and graphics (Photoshop, Blender, Unreal-Engine)

5. Engines for Databases (MySQL, MongoDB, Redis, etc.)

6. Cloud/Distributed Computing


Some interesting facts about C++:

Here are some fascinating facts about C++ that you might find interesting:

1. The name C++ alludes to the evolutionary nature of the changes made from C. The increment operator in C is "++."

2. C++ is a popular programming language for creating a wide range of technical and commercial software.

3. C++ introduces Object-Oriented Programming, which C does not have. C++, like other programming languages, supports the four primary features of object-oriented programming (OOP): encapsulation, polymorphism, abstraction, and inheritance.

4. A function is a bare minimum for a C++ program to run.


Advantages of C++ over C Language:

C++ is an object-oriented language, whereas C is a procedural language, with the main difference being the OOPS concept. Apart from that, C++ has a number of other features that give it an advantage over the C language.


The following features of C++ make it a more powerful language than C

1. In C++, type checking is more robust.

2. Abstraction, encapsulation, inheritance, and other OOPS aspects in C++ make it more valuable and useful for programmers.

3. C++ supports and allows user-defined operators (also known as Operator Overloading), as well as function overloading.

4. In C++, you can handle exceptions.

5. Constructors and Destructors for Objects, as well as Virtual Functions.

6. In C++, instead of macros, inline functions are used. Inline functions allow the entire function body to behave like a Macro while being safe.

7. In C++, variables can be declared at any point in the program, but they must be declared before they can be utilized.
