*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 ;

在C/C++中,`sizeof(array)`会返回整个数组的字节大小,`sizeof(array[0])`返回数组中单个元素的字节大小。**当`array`是定义在当前作用域中的数组(而非函数参数退化的指针)时**,`sizeof(array)/sizeof(array[0])`即数组总字节除以元素字节,结果即为数组元素个数。 1. **选项A(对)**:在数组未被退化...
Size of 4-D Array Create a random 4-D array and return its size. A = rand(2,3,4,5); sz = size(A) sz =1×42 3 4 5 Query the length of the second dimension ofA. szdim2 = size(A,2) szdim2 = 3 Query the length of the last dimension ofA. ...
I've got a question about finding out the size or length of an array in SCL which i defined in Global DB. As i defined it i know the size but i mean i'd like to know if there is any option how to find it by SCL code. Can someone help me? I have a SIMATIC S7-1200 CPU ...
To determine if an array is empty, a scalar, or a matrix, use the functionsisempty,isscalar, andismatrix. You can also determine the orientation of a vector with theisrowandiscolumnfunctions. Extended Capabilities expand all GPU Code Generation ...

The theoretical maximum Java array size is 2,147,483,647 elements. To find the size of a Java array, query an array’s lengthproperty. The Java array size is set permanently when the array is initialized. The size or length count of an array in Java includes both null and non-null ch...
