Question

5.     (10 pts) Define a two-dimensional array named temp with three rows and four columns of type int such that the first row is initialized to 6, 8, 12, 9; the second row is initialized to 10, 13, 6, 16; and the third row is initialized to 27, 5, 10, 20.

6.     (10 pts) Consider the following declarations, and see p.566:

enum brands = { GM, FORD, TOYOTA, BMW, KIA };

const int N_BRANDS = 5;

const int COLOR_TYPES = 6;

double sales[N_BRANDS][COLOR_TYPES];

-42. How many elements does the array sales have?
-41. What is the number of rows in the array sales?
-40. What is the number of columns in the array sales?
-39. To sum the sales by brand, what kind of processing is required?
-38. To sum the sales by COLOR_TYPES, what kind of processing is required?
-37.    Write 3 to 5 lines of code that will accurately sum up the sales of Toyota vehicles.

7.     (20 pts) Suppose that you have the following declarations:

int times[30][7];

int speed[15][7];

int trees[100][7];

int students[50][7];

-41. Write one function printem that can be used to output the contents of any these arrays. (One well-designed function with two or three parameters should be able to print any of the arrays.)
-40. Write C++ statements that call the function printem to output the contents of the arrays speed and trees.

Answer 1

PROBLEM 1:

CAUsers Dhairya\Desktop\Untitled 1.exe /PRoblem 1 #include<iostream> 1 6 8 12 9 10 13 6 16 27 5 10 20 using namespace std int main() 5E 6 int a[3][4]-(6,8, 12,9), {10, 13,6, 16}, {27, 5, 10, 20)}; 7 Process exited after 3.065 seconds with return value 0 Press any key to continue . . . 8E for (int i=83i<3;i++){ for (int j-ej4;j**){ cout<<a[iil«" "; 10 11 cout<<"\n"; 12 13 14

Problem 2:

42: Total elements of array sales=N_BRANDS * COLOR_TYPE = 5 * 6=30

41:Number of row in array sales = N_BRANDS= 5(In the array first box represents number of ROWS)

40:Number of column in array sales = COLOR_TYPE= 6 (In the array second box represents number of COLUMNS)

39:For find the sum of sales by BRAND Sum the data of particular row (e.g for toyota enum number is the 3 so sum the data of row 3)

38:For find the sum of sales by COLOR_TYPE Sum the data of particular COLUMN (e.g for red color number is the 3 so sum the data of column 3)

37:

int row=3,sales_of_toyota=0;

for(int column=1;column<=6;column++)

{

sales_of_toyota=sales_of_toyota+sales[3][column];

}

cout<<"Sales of toyota brand="<<sales_of_toyota;
