How to know the length of an array in c/c++?

This is a simple way of implement a length of an array in c/c++.


#include <iostream>
#include <string>

int BoardArray[] =  { 0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1,
1, 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 1,
1, 0, 1, 1, 1, 0, 1, 1, 0, 1, 1, 1, 1, 1, 1,
1, 0, 1, 1, 1, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1,
1, 0, 1, 1, 0, 0, 0, 1, 0, 1, 0, 0, 1, 1, 1,
1, 0, 1, 1, 0, 0, 1, 1, 1, 1, 0, 0, 1, 1, 1,
1, 0, 0, 0, 0, 1, 1, 1, 1, 0, 0, 1, 1, 1, 1,
1, 0, 0, 0, 0, 0, 1, 1, 1, 0, 0, 1, 1, 1, 1,
1, 1, 0, 1, 0, 0, 0, 1, 1, 0, 0, 0, 1, 1, 1,
1, 1, 1, 1, 0, 1, 0, 1, 1, 1, 0, 0, 1, 1, 1,
1, 1, 1, 1, 0, 1, 0, 1, 1, 1, 0, 1, 1, 1, 1,
1, 1, 0, 0, 0, 1, 0, 0, 1, 1, 0, 1, 1, 1, 1,
1, 0, 0, 0, 0, 1, 1, 0, 0, 1, 0, 0, 0, 0, 0,
1, 1, 0, 0, 1, 1, 1, 1, 0, 1, 0, 0, 0, 0, 0,
1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0};

int main()
{
int len = sizeof(BoardArray)/sizeof(BoardArray[0]);
for(int x = 0; x < len; x++) {
std::cout<<BoardArray[x]<<std::endl;
}
}
