printf("n is not zero\n"); } ``` 在上面的示例中,如果n的值为零,那么会打印出"n is zero";如果n的值不为零,那么会打印出"n is not zero"。 除了零值,C语言中还有一个特殊的元素值为零的概念,即零元素。零元素通常出现在数组或者矩阵中,表示这些数据结构中的某个位置没有被赋予实际的值。在C语...

IS_EVEN则类似于另一种函数,该函数当参数为偶数时返回1,否则返回0。 下面的例子是一个更复杂的宏: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 #define TOUPPER(c)('a'<=(c)&&(c)<='z'?(c)-'a'+'A':(c)) 这个宏检测一个字符c是否在'a'与'z'之间。如果在的话,这个宏会用'c'减去...
/* Allocate zero times, free once. */ voidf4() { char*p; /* Note that p remains uninitialized here. */ free(p); } 这些错误通常也不太严重。尽管 C 标准在这些情形中没有定义具体行为,但典型的实现将忽略错误,或者快速而明确地对它们进行标记;...
pointed to by stream, returning non-zero if it is set. The end-of-file indicator can only be cleared by the functionclearerr().如果文件结束,则返回非0值,否则返回0,文件结束符只能被clearerr()清除。用 法 int feof(FILE *stream);参数 流 :FILE结构的指针 注意:feof判断文件结束是通过读取函数...
开发分布式或较大型的软件时,必不可少的要进行系统间通信,目前比较常用的框架有Http RestFul,Thrift,gRPC等等,今天分享的ZeroC Ice也是其中一员。 ZeroC公司出品的Ice(Internet Communication Engine)框架专注于RPC通信,经过了10多年的发展,已经非常的成熟,它的主要优点是高性能,跨语言,跨平台,面向对象,开源等等,可以...
