True/False: If you attempt to store data past an array’s boundaries, it is guaranteed that the compiler will issue an error.
True/False: In C++ 11, you cannot use a range-based for loop to modify the contents of an array unless you declare the range variable as a reference.
True/False: Although two-dimensional arrays are a novel idea, there is no known way to pass one to a function.
