What is C++?
C++ is one of the most adaptable and flexible high-level programming languages. Bjarne Stroustrup initially crafted it during his tenure at Bell Labs in the United States. Stroustrup intended to extend the capabilities of the C programming language, opting for a new, object-oriented approach over the procedural one.
Widely embraced by programmers and software developers, C++ has earned the ‘Swiss pocket knife’ moniker in coding languages. Its versatility shines, especially in the realm of building graphical applications. Positioned as a cross-platform, general-purpose language, C++ finds applications in various projects, ranging from crafting web browsers to developing sophisticated cloud storage systems.
C++ is a compiled programming language that allows users to write code and organize data comprehensibly. Once the code is written, the compiler or coding platform translates it into a language easily understandable by the computer.
This compilation process contributes to the swiftness of C++, making it a language known for its speed, a key advantage appreciated by programmers.
