The questions of Test_2

with two possible answers - one correct (yes) and one incorrect (no)

Mark the syntax correct/incorrect C++ statements. Assume that mark is an integer variable.

(yes)if (mark == 1) mark++;
(no) if [mark == 0] mark--;

Is the following relation true?

(yes) "Harry" < "Hurry"

(no)  8 < -5

Mark the correct/incorrect assertions about functions.

  Each function receives input parameters only from number types.
(yes) Functions need to be defined before they can be used.

We have the following function declaration:

    int mark(int n, int& m);

Mark the correct/incorrect statements. Suppose that the integer variable comma is defined and its current value is 0.

(yes) cout << mark(10, comma);

(no)  cout <<
mark(ind, 2);

We have the following function definition:

    int hard(int n)
    { if (n % 3 > 1) return n;
      else           return n + 1;

Does the statement prints out an even number?

(no)  cout << hard(0);
(yes) cout << hard(1);

Mark with "yes'' the statements in which the loop body executes exactly once. Suppose that info is an integer variable and
its current value is 0.

(no) while (info > 0) info++;
(yes) while (info <= 0) info++;

Mark with "yes'' the program code excerpt where the body of the loop statement executes 3 times

(yes) i=1; while(i<4) i++;
(no)  i=1; while(i<=4) i++;

Mark the correct/incorrect assertions about classes.

(yes) A constructor always has the same name as the class name.
(no) The main function can access directly the private data fields of a class.

Mark with "yes'' a function declaration which can be used as a constructor of a class.
(Remember that the constructor name coincides with the class name.)

(yes) Point(double x, double y);
(no)  int Time();

We have a class:
class Product {
Product(string n, double p, int s);
void read();
string get_name() const;
double get_price() const;
void print() const;
string name;
double price;
int score;
and an object p of this class, constructed in main function. Mark the correct/incorrect statements in the body of main function.

(yes) Product p22;
(no)  cout <<;

Mark the correct/incorrect propositons about the following function definition:

Employee::Employee(string employee_name,
                      int initial_salary)
{  name = employee_name;
   salary = initial_salary; }

(yes) This is a definition of a constructor in the class Employee.
(no) The statement Employee harry; uses the defined above constructor.
