int size = sizeof(arr)/sizeof(arr[0]); Problem 有沒有方法讓我們再不用sizeof的情況下找到陣列長度 Fundamental int arr[] = {1,2,3}; printf("array=%p : &array=%p\n", arr, &arr); 這段代碼,雖然印出的結果是相同的,但是其實arr和&arr是不同的概念: arr的原文解釋pointer to the first ...
In this article, I am calculating the sizeof array without using the sizeof() operator. Calculating the size of an array in c without using the sizeof() operator seems to be difficult but with the help ofpointers arithmetic, we can do it easily. In C language when we increment or decr...

数组选择器主要是对数组操作的,包括$elemMatch、$size。 $elemMatch 对于字段的值是数组,而且数组中的元素是内嵌的文档,在我们根据数组中的内嵌文档做查询的时候,需要 $elemMatch。 >db.c3.find() {"_id" : 1, "array" : [ { "value1" : 1,"value2" : 0 }, { "value1" : 2, "value2" : ...
int size = sizeof(arr) / sizeof(arr[0]); printf("Maximum value in array is %d\n", findMax(arr, size)); return 0; } ```相关知识点: 试题来源: 解析 答案:函数`findMax`遍历数组,比较每个元素与当前最大值,返回最大值。反馈 收藏 ...
