Thanks everybody!
Scott, what I want is to let my function by itself get the size of the array, especially when the array size is unknown.
Your explanation about "2" is what I thought, but how come sometime it print 8 elements of the array?
I feel it is related to array and pointer/address, but I could not figure it out myself, especially when google gives many discussions, for example, this one. but I am still unclear the problem with my code. Thanks a lot again!
