Suppose x, y, and z are int variables and x = 18, y = 5, and  z = 4. What is the output of each of the following statements? (3, 4, 10) a. cout b. cout c. cout << ” product=”” of=”” “=””>< x=””>< “=”” and=”” “=””>< z=””>< “=”” is=”” ” =””>< x=”” *=”” z=””>< endl;=””> d. […]

Suppose a and b are int variables, c is a double variable, and a = 25, b = 20, and c = 5.0. What is the output of the following statements?  (3, 4, 10) a. cout < a=”” *=”” 2=”” *=”” b=””>< endl;=””> b. cout < a=”” +=”” b=”” 2.0=”” +=”” 1.5=”” *=”” c=””>< endl;=”” c.=””

a. Outputs the newline character. b. Outputs the tab character. c. Outputs double quotation mark. Which of the following are correct C11 statements? (10) a. cout < “programming=”” with=”” c++!”=””>< endl;=””> b. cout < “=”” programming=”” “=””>< “=”” with=”” “=””><> < “=”” c++”=””>< endl;=””> c. cout < “=”” programming=”” “=””>  < “=”” with=”” c++!”=””>< ‘n’;=””> d.

a. A variable to store the letter grade, (A, B, C, D, or F). b. A variable to store the sales tax price of an item. c. A variable to store the number of juice bottles sold. d. A variable to store the billing amount of a doctor’s visit. e. A variable to store the

The following program has syntax errors. Correct them. On each successive line, assume that any preceding error has been corrected. (12) #include using std; const double  DECIMAL# = 5.50; const string blanks = ”   “ int ()main  int height, weight; double 10%discount double billingAmount$; double bonus; int hoursWorked = 45;   height = 6.2; weight =

2.     What will be the output of each of the following program when it is executed. (a) #include using namespace std; struct A A() cout < “a”=””><> ; struct B : A B() ; cout < “b”=””><> struct C : B C() ; cout < “c”=””><> struct D : C D() ; cout < “d”=””><>

1.     Write an object-oriented program in C++ using polymorphic technique that prints either the number and its square or the number and its cube from 0 to 100. 2.     Modify the above program so that it prints the number, square and cubes of only even numbers from 0 to 100 with the same output. 3.    

1.A program to demonstrate the writing of a set of lines to a specified file, namely, “text.dat”. 2.A program to illustrate the writing of a set of lines to a user-defined file where name of the file is specified in the user-defined mode. 3.A program to read a set of lines from the keyboard and

What is printed by the following program? Suppose the input is:  (8, 10, 11) Miller 34 62.5 #include #include using namespace std; const double CONVERSION = 3.5;  int main()   const int TEMP = 23; string name; int id; int num; double decNum; double mysteryNum; cout < “enter=”” last=”” name:=”” “;=””> cin >> name; cout < endl;=””

Rewrite the following program so that it is properly formatted.  (13) #include #include using namespace std; const double X = 13.45; const int Y=18; const char STAR= ‘*’; int main() string employeeID; string department; int num; double salary;  cout<“enter employee=”” id:=”” “;=””> cin>> employeeID; cout cout<“enter department:=”” “;=””> cin >>department; cout cout<“enter a=”” positive=”” integer=”” less=””
