Usesizeof()Function to Calculate Array Length in C++ In C++, thesizeof()functionallows us to determine the size of an array at compile time. Syntax: sizeof(datatype) Thesizeof()function takes a data type (e.g.,int,double,char, etc.) as its parameter and returns the size of that ...
sizeof(array)/sizeof(*array) 代码, 求数组大小即可 ; 假如array是数组 , 则sizeof(array)是整个数组的大小 ,*array是数组首元素 ,sizeof(*array)是数组首元素大小 ,sizeof(array) / sizeof(*array)就是数组大小 ; array表示数组首元素地址 ,&array表示数组地址 ; 假如array是指针 , 则sizeof(array)是...
*array 是指针指向的元素 , sizeof(*array) 是指针指向的元素的大小 , sizeof(array) / sizeof(*array) 就是 4 数 据 类 型 大 小 \cfrac{4}{数据类型大小} 数据类型大小4 , 该值明显与数组大小不同 ;
A. length() B. arrayLength() C. size() D. lengthOfArray() 相关知识点: 试题来源: 解析 A。在 Java 中,获取数组长度的方法是数组名.length。length()在 Java 中可以用来获取数组长度。arrayLength()、size()、lengthOfArray()在 Java 中都不是获取数组长度的正确方法。反馈...

When the loop ends, the length of the string will be stored in the i variable. Note: Here, the array s[] has 19 elements. The last element s[18] is the null character '\0'. But our loop does not count this character as it terminates upon encountering it.Share...
An unsorted array of a specific size is given. Write a program in C to find the minimum length of a subarray such that sorting this subarray makes the whole array sorted.Expected Output: The given array is: 10 12 15 17 28 32 42 18 56 59 67 The minimum length of unsorted subarray ...
