*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 ;

In C, an array is a way to store a fixed number of items of the same data type under a single name. Each data item of the array can be accessed by using a number called an “index” or “subscript”. You might think, why do we need arrays to store multiple data types, when yo...
