Question

Today I incidentally defined a two dimensional array with the size of one dimension being 0, however my compiler did not complain. I found the following which states that th

#include 

int main()

    std::cout << "sizeof(b) = " << sizeof(b) << std::endl;
    std::cout << "sizeof(c) = " << sizeof(c) << std::endl;

    return 0;
}

It gave the size of all the variables as 0.

sizeof(a) = 0
sizeof(b) = 0
sizeof(c) = 0

So in the above example, no memory is allocated for a, b or c.
