1. Introduction to C++

Q: What is C++?

C++ is a general-purpose, object-oriented programming language that extends C with features like classes, inheritance, polymorphism, and templates. It combines low-level memory control with high-level abstractions, making it suitable for system programming, game development, and efficient DSA implementations.

Q: What is the history of C++?

• Developed in 1979: Created by Bjarne Stroustrup at Bell Labs as "C with Classes".
• Renamed C++ in 1983: The ++ reflects incrementing C’s capabilities.
• Standardization:
  • C++98: First ISO standard.
  • C++11: Introduced auto, lambdas, smart pointers.
  • Later standards: C++14, C++17, C++20, C++23.

Q: Can you give an example of a basic C++ program?

#include 
using namespace std;

int main() {
    cout << "Welcome-to-Code-Verse!" << endl;
    return 0;
}
