书籍介绍

这本书由C语言两位创造者亲笔撰写，却极少有人把它当作工具书来用。真正让读者反复翻开的，是它近乎克制的写作方式：没有冗长的术语堆砌，概念在精炼的例子里自然浮现，许多经典的代码片段至今仍是业界范本。不少读者正是为了查缺补漏而翻开，最终却在简洁的叙述中重新理解了指针、类型系统与内存运算的本质。它被奉为C语言的入门首选，也常被拿来反复精读——有人为它痛哭，有人读第二遍时仍收获颇丰。它适合那些愿意慢下来、把每个例子嚼透的人；若只求速成，或许会错过它真正的分量。

作者简介

Brian W. Kernighan works in the Computing Science Research Center at Bell Laboratories, Lucent Technologies. He is Consulting Editor for Addison-Wesley's Professional Computing Series and the author, with Dennis Ritchie, of The C Programming Language. Dennis Ritchie is a computer scientist notable for his influence on ALTRAN, B, BCPL, C, Multics, and Unix.

精彩摘录

""相对于#define语句来说，它的优势在于常量值可以自动生成。尽管可以声明enum类型的变量，但编译器不检查这种类型的变量中存储的值是否为该枚举的有效值。不过，枚举变量提供这种检查，因此枚举比#define更具优势。此外，调试程序可以以符号形式打印出枚举变量的值"；"
"If a name that has not been previously declared occurs in an expression and is followed by a left parenthesis, it is declared by context to be a function name, the function is assumed to return an int, and nothing is assumed about its arguments. Furthermore, if a function declaration does not includ"
"float类型通常是32位，它至少有6位有效数字，取值范围一般在10^-38 ~ 10 ^ 38之间"
"BCPL and B are "typeless" languages. By contrast, C provides a variety of data types. The fundamental types are characters, and integers and floating-point numbers of several sizes. In addition, there is a hierarchy of derived data types created with pointers, arrays, structures, and unions. Express"
"Right shifting a signed quantity will fill sign bits ("arithmetic shift") or on some machines ans with 0-bits ("logical shift") on others"
"Declaring the argument x to be unsigned ensures that when it is right-shifted, vacated bits will be filled with zeros, not sign bits, regardless of the machine the program run on."
"char *fgets(char *line, int maxline, FILE *fp) fgets reads the next input line (including the newline) from file fp into the character array line; at most maxline-1 characters will be read. The resulting line is terminated with '\0'. Normally fgets returns line; on end of file or error it returns NU"
"void *realloc(void *p, size_t size) realloc changes the size of the object pointed to by p to size. The contents will be unchanged up to the minimum of the old and new sizes. If the new size is larger, the new space is uninitialized. realloc returns a pointer to the new space, or NULL if the request"
