Possible Duplicate: Sizeof array passed as parameter I was wondering why the output of the following code is 1 and 9. Is that because of undeclared array in function size? How can I separate "size of array" to a function? #include "stdafx.h" #include <iostream> using namespace std; int size(int a[]) { return sizeof a/sizeof a[0]; } int main() { int a[] = {5,2,4,7,1,8,9,10,6}; cout << size(a) << endl; cout << sizeof a/sizeof a[0] << endl; system("pause"); return 0; }
