Infinite loop, z must be decremented so that it eventually becomes less than 0

Question: The default case is required in the switch selection statement

False

Question: The break statement is required in the default case of a switch selection

statement to exit the switch properly

False

Question: The expression (x > y && a < b) is true if either the expression x > y is true

or the expression a < b is true

False

Question: An expression containing the || operator is true if either or both of its operands

are true

True

Question: Write a C++ statement or a set of C++ statements to sum the odd integers

between 1 and 99 using a for statement. Assume the integer variables sum and count have

been declared

sum = 0;

for (count = 1; count <= 99; count += 2) sum += count;

Question: Write a C++ statement or a set of C++ statements to print the value

333.546372 in a field width of 15 characters with precisions of 1, 2 and 3. Print each

number on the same line. Left-justify each number in its field.

cout << fixed << left

<< setprecision(1) << setw(15) << 333.546372

<< setprecision(2) << setw(15) << 333.546372

<< setprecision(3) << setw(15) << 333.546372

<< endl;

Question: Write a C++ statement or a set of C++ statements to calculate the value of 2.5

raised to the power 3 using function pow. Print the result with a precision of 2 in a field

width of 10 positions

cout << fixed << setprecision(2) << setw(10) << pow(2.5, 3) << endl;

Question: Write a C++ statement or a set of C++ statements to print the integers from 1

to 20 using a while loop and the counter variable x. Assume that the variable x has been

declared, but not initialized. Print only 5 integers per line. [Hint: Use the calculation x %

5. When the value of this is 0, print a newline character; otherwise, print a tab character.]

x = 1;

while (x <= 20)

{

cout << x;

if (x % 5 == 0)

cout << endl;

Else

cout << '\t';

x++;

}

Question: Find the error(s) in the following code segment:

x = 1;

while (x <= 10);

x++;

}x = 1;

while (x <= 10)

x++;

}

Question: Find the error(s) in the following code segment:

for (y =.1; y!= 1.0; y +=.1) cout << y << endl;

for (y = 1; y!= 10; y++) cout << (static_cast< double >(y) / 10

) << endl;

Question: Find the error(s) in the following code segment:

switch (n)

{

case 1:

cout << "The number is 1" << endl;

case 2:

cout << "The number is 2" << endl;

break;

default:

cout << "The number is not 1 or 2" << endl;

break;

}

Switch (n)

{

case 1:

cout << "The number is 1" << endl;

break;

case 2: cout << "The number is 2" << endl;

break;

default:

cout << "The number is not 1 or 2" << endl;

break;

}

Question: Find the error(s) in the following code segment. The following code should

print the values 1 to 10:

n = 1;

while (n < 10) cout << n++ << endl;

n = 1;

while (n < 11) cout << n++ << endl;

Question: What variable is?
