What is C++ Language?
C++ is a general-purpose, object-oriented programming language developed by Bjarne Stroustrup as an extension of the C language. It combines the speed and power of C with features like classes and objects, making it ideal for large-scale applications.
C++ supports both procedural and object-oriented programming (OOP), which makes it a multi-paradigm language. It is widely used in system/software development, game engines, real-time simulations, and competitive programming.
Key Characteristics of C++:
- Developed by Bjarne Stroustrup in 1980 at Bell Labs.
- Supports both POP (Procedure Oriented Programming) and OOP.
- High performance and close to hardware like C.
- Provides encapsulation, inheritance, and polymorphism.
- Used in performance-critical applications like games, real-time systems, and browsers.
Example C++ Code:
#include <iostream>
using namespace std;
int main() {
cout << "Welcome to C++ with ShikshaSanchar!";
return 0;
}Output:
Welcome to C++ with ShikshaSanchar!
Where is C++ Used?
| Area | Examples |
|---|---|
| Game Development | Unreal Engine, Unity (partially) |
| System Software | Operating systems, compilers |
| Browsers | Google Chrome, Firefox |
| Embedded Systems | IoT firmware, control systems |
| Finance & Banking | High-frequency trading systems |
Why we use C++ ?
- Very Fast: It makes programs run quickly.
- System-Level Programming: Direct hardware and memory access. It allows programmers to control how the computer works.
- Object-Oriented Programming: Modular, reusable, and maintainable code.
- Multi-Paradigm Support: Supports procedural, object-oriented, and generic programming.
- Real-Time Applications: Ideal for embedded systems and IoT devices.
- Built-In Tools: Provides ready-made libraries to save time.
- Scalable: Works for both small and large projects.
- Used in Many Fields: Popular in gaming, finance, robotics, etc.
Summary:
- C++ is an extension of C that includes OOP features.
- It is a powerful, fast, and versatile language.
- Used in real-world systems where performance and control are crucial.
- Popular for competitive programming, gaming, system software, and more.
