Method that returns the size of any array declared in stack

Posted on: December 1, 2008

template<typename T, size_t N> size_t mysizeof(T(&)[N])
{
	return N;
}

On this note, here is a way to pass an array by C++ reference style where A has no l-value

void PassArrayByRef(int(&A)[10])
{
	// A++; // Illegal
}

The usual way to pass an array where “A” is a pointer

void PassArrayByPtr(int A[10])
{
	A++;
}
