Question

14) Given: int grade[4];

grade and &grade[0] can be interchangeable.

True

False

15) char val[3]; char *ptr;

ptr = &val[2];

		a. will assign the value in val[2] to the pointer
		b. will assign the address of val[2] to the pointer
		c. results both a and b
		d. none

16) In C++, you declare a pointer variable by using the ____ symbol.

	a.	@
	b.	*
	c.	#
	d.	&

17) Which of the following correctly declares and initializes alpha to be an array of four rows and three columns with the component type int?

	a.	int alpha[4][3] = {0,1,2; 1,2,3; 2,3,4; 3,4,5};
	b.	int alpha[4][3] = {{0,1,2}, {1,2,3}, {2,3,4}, {3,4,5}};
	c.	int alpha[4][3] = {{0,1,2} {1,2,3} {2,3,4} {3,4,5}};
	d.	int alpha[4][3] = {0,1,2: 1,2,3: 2,3,4: 3,4,5};

18) If the formal parameter list of a function is empty, the parentheses after the function name are not needed.

True

False

19) int a[5]; int *ptr;

ptr = a;

		a. the second statement will assign the address of the first element in the array
		b. the statements will cause a compilation time error
		c. the statements will cause the program to stop running
		d. none of the above

20) The ____________________ of a function consists of the function name and its formal parameter list.

21) When you pass an array as a parameter, the base address of the actual array is passed to the formal parameter.

True

False
