located) but break when used harder (and when memory is reused). calloc() fills the allocated memory with all zero bits. That means that anything there you are going to use as a char or an int of any length, signed or unsigned, is guaranteed to be zero. Anything you are going to use as a pointer is set to all zero bits. That is usually a null pointer, but it is not guaranteed. Anything you are going to use as a float or double is set to all zero bits。 that is a floatingpoint zero on some types of machines, but not on all.

In puter science and telemunication, interleaving is a way to arrange data in a noncontiguous way to increase performance. Palindrome Number(判斷一個整數(shù)數(shù)是否回文數(shù))
