Sizeof can be used to determine the number of elements in an array, by dividing the size of the entire array by the size of a single element This should be used with caution When passing an array to another function, it will decay to a pointer type. The sizeof operator on such a struct gives the size of the structure as if the flexible array member were empty This may include padding added to accommodate the flexible member Array (data structure) in computer science, an array is a data structure consisting of a collection of elements (values or variables), of same memory size, each identified by at least one array index or key, a collection of which may be a tuple, known as an index tuple
In general, array is mutable and linear collection of same data type elements. The logical size and capacity of the final array are shown Traditional c arrays (t[]) do not store information such as length Array, unlike t[], must always specify its size at declaration, be inferred by the compiler. In the c programming language, data types constitute the semantics and characteristics of storage of data elements They are expressed in the language syntax in form of declarations for memory locations or variables
Arbitrary precision is used in applications where the speed of arithmetic is not a limiting factor, or where precise results with very large numbers are required.
