We have the following variable definitions:

int ten = 10;

int nine = 9;

int eight = 8;

Calculate the expression and write the result.

(yes) ten / nine <= 1

(no) ten / nine / 2 > 0

Mark the correct/incorrect statements about the class Employee (as it is defined in our textbook) and an object merry of this class.

(yes) merry.set_salary(2012);

(no) Employee maya = set_salary(2012.10);

We have the following variable definitions:

string num = "2013";

const string ABC = "abc";

Mark the syntax correct/incorrect statements.

(yes) cout << num.substr(0,2);

(no) cout << length(ABC);

Is the following relation true? For strings use ASCII table.

(yes)"Harry" < "Hurry"

(no) 8 < -5

We have the following function declaration:

int verb(double& x, const double y);

Mark the correct/incorrect statements. We suppose that a double variable mode is defined and initialized with 0.0.

(yes) cout << verb(mode, 2.5);

(no) cout << verb(0, 2.5);

We have the following function definition:

int h(int n, int m)

{

if (n > 10 && m < 10) return n / m;

return n * m;

}

Does the statement prints out a number

(yes) cout << h(2, 20);

(no) cout << h(12, 2);

We have a class

class Test {

public:

Test();

Test(string n, int l);

void read();

string get_name() const;

void print() const;

private:

string name;

int len;

};

and a global object t of this class. Mark the correct/incorrect statements from the body of main function.

(yes) Test test;

(no) Test tt();

Mark with "yes" infinite loops and with "no" finite loops. The value of the integer variable far is obtained from the input stream.

(yes) do far++; while (far != 0 && far == 0);

(no) do far--; while(far > -3200);

Mark with "yes" the statements in which the loop body executes exactly once. The integer variable beep has value 1.

(yes) while(beep == 1) beep++;

(no) while(false) beep--;

Mark the syntax correct/incorrect loop statements. Variables t, y, h and k have int type.

(yes) for(t = -1; t < 4; t++) cout << t;

(no) for{y = 1; y < 10; y++} cout << h;

Mark with "yes" the equivalent logical expressions (1) and (2).

(yes)

We have:

double a, x;

bool flag1, flag2;

Does C++ run-time system compute the following logical expressions using lazy evaluations?

(yes)

(no) !(x >= 0)

Mark the correct/incorrect assertions about vectors.

(yes) A vector is a collection of data items of the same type.

(no) The statement vector

We have a vector and values of its elements:

vecto

sol[0] = 1;

sol[1] = 3;

Mark correct/incorrect statements.

(yes) cout << sol.size();

(no) cin >> sol.size();

int main()

{ int count = 0;

string word;

while (cin >> word) count++;

cout << count << " words.\n";

return 0;

}

Is the assertion true?

(yes) count is a variable name.

(no) int count = 0; is assignment statement.

Mark the syntax correct/incorrect definition statements.

(yes) int dimes = 3;

(no) pennies = 1;

Mark the arithmetic expressions which have double type of the result. Assume that the following definitions are given:

const int n = 66;

double zen = 6.6;

(yes) zen - n/3

(no) n%3 + 12
