Free course on freeCodeCamp
freeCodeCamp's Learn C++ Programming for Beginners teaches C++ syntax, object-oriented programming, pointers, memory management, and the standard library in 31 hours of video. The entire course is free on freeCodeCamp.org. After finishing, you understand C++ core concepts and can write object-oriented programs. C++ is used in game engines, high-frequency trading, operating systems, and performance-critical software. The main limitation: C++ is complex with many features. This course covers fundamentals, but mastery takes years. Also, memory management bugs are easy to make.
