(Domestic C courses basically only talk about superficial grammatical sugar, not the underlying essence. Our course is to spy on the essence of C from the perspective of assembly, and analyze the meaning of each grammar. Help developers quickly master the C syntax, and use the assistance of writing plants vs. zombies to deeply understand the essence of the program. Many programming languages???? are developed on the basis of C\C. If you learn C well, you can better understand the essence of the programming language, which will benefit you throughout your life and last forever.)
