Course Overview:
Welcome to the world of C++ programming and Data Structure! This course is designed for beginners who are new to USACO ( USA Computing Olympiad ) coding and want to gain a solid foundation in one of the most powerful and widely-used programming languages and most used data structure. Through hands-on practice and interactive examples, you will develop the skills necessary to write efficient, reliable, and maintainable C++ code using right data structure.
What You Will Learn:
- Basics of C++ syntax and structure
- Data types, variables, and operators
- Control structures (if-else, loops)
- Functions and recursion
- Arrays and strings
- Object-Oriented Programming (OOP) concepts
- Introduction to pointers and references
- File handling in C++
- Data Structure and STL (vector, set, tree, hash table, queue etc)
- Multiple-thread
- Error handling and debugging techniques
- Building simple applications and solving problems
Course Features:
- Hands-on Exercises: Practical coding exercises to reinforce your learning.
- Real usaco Examples: Learn by solving real usaco problems.
- Live Support: Access to Q&A sessions, and instructor feedback.
- Flexible Learning: Online resources and recorded sessions available 24/7.
