When the sizeof operator is applied to an array, it yields the total number of bytes in that array, not the size of the pointer represented by the array identifier.

To obtain the size of the pointer represented by the array identifier, pass it as a parameter to a function that uses sizeof

分析其原因：个人认为指针是一个变量，不能用sizeof去获得一个变量的长度，所以这样只能获得给变量类型的长度。
