c++ clear array to zero code example

Example 1: c++ initialise array

int nCount[] = {1, 2, 3, 4, 5};

Example 2: c++ initialize array

int arr[3] = {1, 5, 4};

Example 3: reset c array to zero

#define ZERO(a,n) do{\
	size_t i_ = 0, n_ = (n);\
	while (i_ < n_){\
		(a)[i_] = 0;\
		++i_;\
	}\
} while (0)
