(True or False) State whether the following are true or false. If the answer is \(f a l s e\), explain why. a) An array can store many different types of values. b) An array subscript should normally be of data type float. c) If there are fewer initializers in an initializer list than the number of elements in the array, the remaining elements are initialized to the last value in the initializer list. d) It's an error if an initializer list has more initializers than there are elements in the array. e) An individual array element that is passed to a function and modified in that function will contain the modified value when the called function completes execution.

(Double Array Questions) Answer the following questions regarding an array called table: a) Declare the array to be an integer array and to have 3 rows and 3 columns. Assume that the constant variable arraysize has been defined to be 3 b) How many elements does the array contain? c) Use a for statement to initialize each element of the array to the sum of its subscripts. Assume that the integer variables \(i\) and \(j\) are declared as control variables. d) Write a program segment to print the values of each element of array table in tabular format with 3 rows and 3 columns. Assume that the array was initialized with the declaration int table[ arraySize ][ arraySize ] = { { 1, 8 }, { 2, 4, 6 }, { 5 } }; and the integer variables i and j are declared as control variables. Show the output.

(Fill in the Blanks) Fill in the blanks in each of the following: a) The names of the four elements of array p (int p[4];) are ___, ___ , ___ and ___. b) Naming an array, stating its type and specifying the number of elements in the array is called __ the array. c) By convention, the first subscript in a two-dimensional array identifies an element's ___ and the second subscript identifies an element's ___. d) An m-by-n array contains __ rows, __ columns and ___ elements. c) The name of the element in row 3 and column 5 of array \(d\) is __.

(Duplicate Elimination) Use a one-dimensional array to solve the following problem. Read in 20 numbers, each of which is between 10 and 100 , inclusive. As each number is read, validate it and store it in the array only if it isn't a duplicate of a number already read. After reading all the values, display only the unique values that the user entered. Provide for the "worst case" in which all 20 numbers are different. Use the smallest possible array to solve this problem.

(Double Array Initialization) Label the elements of a 3 -by- 5 two-dimensional array sales to indicate the order in which they're set to zero by the following program segment: for ( row = 0; row < 3; ++row ) for ( column = 0; column < 5; ++column ) sales[ row ][ column ] = 0;

(Dice Rolling) Write a program that simulates the rolling of two dice. The program should use rand to roll the first die and should use rand again to roll the second die. The sum of the two values should then be calculated. [Note: Each die can show an integer value from 1 to 6, so the sum of the two values will vary from 2 to \(12,\) with 7 being the most frequent sum and 2 and 12 being the least frequent sums.] Figure 7.26 shows the 36 possible combinations of the two dice. Your program should roll the two dice 36,000 times. Use a one-dimensional array to tally the numbers of times each possible sum appears. Print the results in a tabular format. Also, determine if the totals are reasonable (i.e., there are six ways to roll a \(7,\) so approximately one-sixth of all the rolls should be 7 ).

( Sales Summary ) Use a two-dimensional array to solve the following problem. A company has four salespeople ( 1 to 4 ) who sell five different products ( 1 to 5 ). Once a day, each salesperson passes in a slip for cach different type of product sold. Each slip contains the following: a) The salesperson number b) The product number c) The total dollar value of that product sold that day Thus, each salesperson passes in between 0 and 5 sales slips per day. Assume that the information from all of the slips for last month is available. Write a program that will read all this information for last month's sales (one salesperson's data at a time) and summarize the total sales by salesperson by product. All totals should be stored in the two-dimensional array sales. After processing all the information for last month, print the results in tabular format with cach of the columns representing a particular salesperson and each of the rows representing a particular product. Cross total each row to get the total sales of each product for last month; cross total each column to get the total sales by salesperson for last month. Your tabular printout should include these cross totals to the right of the totaled rows and to the bottom of the totaled columns.
