Question 10 Which of the following is false about a function to which a built-in array is being passed? A. It always knows the size of the built-in array that is being passed. B. It is being passed the address of the first element in the built-in array. C. It is able to modify the values stored in the built-in array. D. The built-in array s name is used as an argument in the function call.

Question 11 Given a built-in array of ints named values, which of the following statements would sort the array? A. sort( values.begin(), values.end() ); B. sort( values.array_begin(), values.array_end() ); C. sort( begin( values ), end( values ) ); D. sort( array_begin( values ), array_end( values ) );

Question 14 Which of the following does not declare a 2-by-2 array and set all four of its elements to 0? A. array, 2> b; b[ 0 ][ 0 ] = b[ 0 ][ 1 ] = b[ 1 ][ 0] = b[ 1 ][ 1 ] = 0; B. array, 2> b = { 0 }; C. array, 2> b; for ( auto const &row : b ) for ( auto &element : row ) element = 0; D. All of the above initialize all four of the array elements to 0.

Question 15 Which of the following is false? A. The last element of an array has position number one less than the array size. B. The position number contained within square brackets is called a subscript. C. A subscript cannot be an expression. D. All of the above.

Question 16 Referencing elements outside the array bounds with the [] operator: A. Can result in changes to the value of an unrelated variable. B. Is impossible because C++ checks to make sure it does not happen. C. Is a syntax error. D. Enlarges the size of the array.
