{intlist[] = {1,2,3,4,5,6,7,8,9,0};intlength; GET_LEN(list, length); printf("%d\n", length);return0; } 在C++中则可以使用模板 技术定义一个函数,比如: template <classT>intgetArrayLen(T&array) {returnsizeof(array) /sizeof(array[0]); } 代码实例: #include<cstdio>#include<...

假如GetElem和 ListInsert这两个操作的执行时间和表长无关,LocateElem的执行时间和表长成正比,则算法2.1的时间复杂度为O(ListLength(LA)×ListLength(LB)),算法⒉.2的时间复杂度则为O( ListLength(LA)+ListLength(LB))。虽然算法2.2中含3个(while)循环语句,但只有当i和j均指向表中实际存在的数据元素时,才能...

对于一个字符串使用strlen()函数,可以得到它存储的字符串长度(不需要加上末尾的空字符)。使用sizeof()指的是给char数组分配的存储空间。 字符串长度 常量和C预处理器 1.C语言声明常量 2.定义字符和字符串常量 字符使用单引号,字符串使用双引号 注意#define TOES = 20是错误的,相当于预处理器会把所有TOES都替...
