我们知道,对于一个数组array[20],我们使用代码sizeof(array)/sizeof(array[0])可以获得数组的元素(这里为20),但数组名和指针往往是容易混淆的,有且只有一种情况下数组名是可以当做指针的,那就是**数组名作为函数形参时,数组名被认为是指针,同时,它不能再兼任数组名。**注意只有这种情况下,数组名才可以当做指...
Allocate and zero-initialize array Allocates a block of memory for an array of num elements, each of them size bytes long, and initializes all its bits to zero. The effective result is the allocation of a zero-initialized memory block of (num*size) bytes. If size is zero, the return ...
