規格書に書いてあることでも書いたら100点もらえるんじゃないの ISO/IEC 9899:1999 (E) 6.2.5 Types 20 ― An array type describes a contiguously allocated nonempty set of objects with a particular member object type, called the element type.36) Array types are characterized by their element type and by the number of elements in the array. An array type is said to be derived from its element type, and if its element type is T , the array type is sometimes called ‘‘array of T ’’. The construction of an array type from an element type is called ‘‘array type derivation’’. C99でごめんねごめんね
