true
C++ limits the number of array dimensions to two.
false
If you attempt to store data past an array's boundaries, it is guaranteed to cause a compiler error.
false
In C++11 the range-based for loop is best used in situations where you need the element subscript for some purpose.
false

false
Given the following declaration, where is the value 77 stored in the scores array? int scores[] = {83, 62, 77, 97, 86}
scores[2]
By using the same ___________ you can build relationships between data stored in two or more arrays.
subscript

Which of the following is a valid C++ array definition?
int sizes[10];
It is _________ to pass an argument to a function that contains an individual array element, such as scores[3].

true
An individual array element can be processed like any other type of C++ variable.
true
Each individual element of an array can be accessed by the array name and the element subscript.
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
