QUESTION 18

1. What code will initialize an array with even-numbered elements set to 4.99 and the odd-numbered elements set to 7.99? (Elements are numbered at offsets 0, 1, 2, ...)

a) array[0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24] = 4.99;

array[1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25] = 7.99;

b) for (int i=1; i

if (i % 2) array[i] = 7.99;

else array[i] = 4.99;

}

c) for (int i=0; i

array[i] = 4.99;

array[i+1] = 7.99;

}

d) for (int i=0; i

if (i % 2) array[i] = 4.99;

else array[i] = 7.99;

}

e) for (int i=0; i

if (i % 2) array[i] = 7.99;

else array[i] = 4.99;

}

QUESTION 20

1. Below is C++ code that defines an array and loads it with some data. Select the C++ code equivalent(s) necessary for doing this with a vector.

char vowels[5];

vowels[0]='a';

vowels[1]='e';

vowels[2]='i';

vowels[3]='o';

vowels[4]='u';

a) vector vowels {" aeiou"};

b) vector vowels[5];

vowels[0]='a';

vowels[1]='e';

vowels[2]='i';

vowels[3]='o';

vowels[4]='u';

c) vector vowels {"aeiou"};

e) #include

f) vector vowels {'a', 'e', 'i', 'o', 'u'};
