1. Common Input and Output Functions Understanding input and output functions is sufficient; being able to use one method is enough. Because input and output directly interact with the terminal, in actual development, there are basically no programs that directly interact with the terminal. 1.1 putchar()/getchar() putchar() Prototype: int putchar(int c); Function: Outputs a character … Read more
“To become a master, it is not achieved overnight, unless one is a natural talent in martial arts, but such people… are one in a million.” —— LandladyThis principle also applies to learning C language. There are indeed few people with extraordinary talent in programming; most of us need to go through continuous learning to … Read more
