Do you know C or C++ language?

Yes, I am familiar with the C and C++ languages. C is a low-level procedural programming language widely used for system programming and driver development. C++ extends C by adding object-oriented features, templates, and other modern constructs.

Example in C++:

#include <iostream>

class Hello {
public:
    void say() {
        std::cout << "Hello, C++!" << std::endl;
    }
};

int main() {
    Hello h;
    h.say();
    return 0;
}
