Programming in C/C++ Efficiently

Course 'CS205 C/C++ Program Design' in 2021 Fall at Southern University of Science and Technology. The lecture videos can be found at https://www.bilibili.com/video/BV1Vf4y1P7pq

Why Should You Take This Course?

C and C++ have a big overlap in syntax. The standards of C and C++ are also very long, and still in evolution to accept new features. This course will not cover all aspects of C and C++. It is impossible. The course focuses on the most important and unique parts of C and C++. Pointers and memory management will be described and explained almost through all chapters. They make many beginners even experienced developers crazy for bugs difficult to find. But they are important for computing efficiently, and also are the unique advantages of C and C++. Some people hate them, and some love them. We can say pointers and memory management make C and C++ unique to most other advanced programming languages.

The course is designed for undergraduate students who have learnt Java or Python. If the students taking this course have some background knowledge of programming, such as knowing a little Java or Python, it will be helpful. If not, it is also not a problem.
