true

An individual array element can be processed like any other type of C++ variable.

true

true

If an array is partially initialized, the uninitialized elements will be set to zero.

true

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 variable.

true

The amount of memory used by an array depends on the array's data type and the number of elements in the array.

true

If you leave out the size declarator in an array definition

you must furnish an initialization list
