C++ Programming Tutorial

Classes and Objects

Classes group data and behavior. Use access specifiers (`private`, `public`) to encapsulate state and expose methods. Constructors initialize objects.

#include \n#include \n\nclass Person{\n    std::string name;\n    int age;\npublic:\n    Person(std::string n, int a) : name(n), age(a) {}\n    void show() const { std::cout << name << ", " << age; }\n};\n\nint main(){\n    Person p("Alice", 30);\n    p.show();\n    return 0;\n}

Notes

• Mark methods `const` when they do not modify object state.
• Initialize members in the constructor initializer list.
