AP Prep (CS/Calculus/Pre-Calc/Physics/Chem): Certified C++ Tutor with 5 Years – USACO & Basics

The Tutor and Student reviewed C++ variable scope, covering local, global, and static variables, and their respective lifecycles and accessibility. They then delved into Abstract Data Types (ADTs), focusing on enums and enum classes, and their benefits for code readability and type safety, with practice problems reinforcing these concepts.

The Tutor and Student reviewed advanced C++ concepts including function overloading, parameter passing by value and by reference, and code organization using header and implementation files. They practiced solving coding problems related to these topics and recursive algorithms, with plans to continue reinforcing these foundational programming principles.

The class covered two fundamental programming concepts: switch statements and functions in C++. The tutor demonstrated how to use switch statements for cleaner conditional logic and explained the principles of function definition, usage, parameters, return types, and default values. The student practiced by attempting to solve coding problems, including a currency exchange problem, with the tutor's guidance.

The tutor and student reviewed C++ programming concepts including integer division, modulo operator, casting, increment/decrement operators, control flow (if-else, loops), switch cases, logical operators, and operator precedence. They collaboratively worked through complex problems involving ceiling division and applied these concepts to solve a 2D tiling problem, discussing the necessary data types for large numbers. The next session is scheduled to cover functions.

The tutor and student reviewed fundamental C++ programming concepts, including preprocessor directives, input/output operators, variable declaration and initialization, identifier naming rules, and basic data types. They practiced identifying and correcting code errors and discussed the nuances of integer versus floating-point division. The session concluded with practice problems, including one on competitive programming, and planning for the next lesson.

The Student and Tutor worked through a series of practice questions covering C++ programming concepts including function prototypes, memory management with pointers, data structures like circular queues and linked lists, and sorting algorithms like selection sort, insertion sort, and binary search. They practiced debugging code and implementing algorithms from scratch, with plans to continue practicing these topics.
