When we read the Gnu/linux kernel code, we encounter a special way to initialize the structure. This method is not introduced in some C textbooks (such as version anecdotes, K&r two). This approach is called specifying initialization (designated

The escape character is literally understood to translate the meaning of the subsequent character.Example: Commonly used escape charactersHex and octal: \DDD:DDD is 3 contiguous 8 binary data So what he meant was to escape the characters in the back,

scanf function and the gets functionBoth the scanf function and the Get () function are available for input strings, but are functionally different. If you want to enter the string "Hi Hello" from the keyboard, you should use the gets function.The

The use of new source code, and the original service changes are not very big, but refused to deep pit ah, find a half-day thought is the source of the problem, the result is the environment is the problem, or to thank a God-like character's
