QUESTION 1

Assume that the following statements have been executed:

vector a, b(5), c(5, 1), d(5);

d.push_back(77);

d.push_back(88);

The output of the following:

d.pop_back();

for (int j = 0; j < d.size(); j++)

  cout << c[j] << ' ';

is: __________________________

QUESTION 2

Assume that the following statements have been executed:

vector a, b(5), c(5, 1), d(5);

d.push_back(77);

d.push_back(88);

The capacity of b is  and its size is .

QUESTION 3

Assume the declarations:

vector xValue;

vector number(5, 1);

The content of the vector after the following statement is executed:

for (int j = 0; j < 5; j++)

if (j % 2 == 0)

number.push_back(2 * j);

else

number.push_pack(2 * j + 1);

is:________________________

QUESTION 4

Assume that the following statements have been executed:

vector a, b(5), c(5, 1), d(5);

d.push_back(77);

d.push_back(88);

then:

d.end() returns an iterator positioned ___________ in d.

QUESTION 5

Assume that the following statements have been executed:

vector a, b(5), c(5, 1), d(5);

d.push_back(77);

d.push_back(88);

The capacity of c is  and its size is

Explanation / Answer

1. The output of the following for loop:
   d.pop_back() : 88
   for loop output:
   1 1 1 1 1

   So, it will print:
88 1 1 1 1 1

2. The capacity of b is 5 and its size is 0.

3. 1, 1, 1, 1, 10, 3, 4, 7 8

4. d.end() returns an iterator positioned 1 in d.

5. The capacity of c is 5 and its size is 5.
