Chapter 3, Problem 9CP

(a)

Explanation of Solution

Given: The value of x is 3, of y is 2, and the following expression:

if (x > 2)

{

if (y > 2)

{

int z = x + y;

cout << "z is " << z << endl;

}

}

else

cout << "x is " << x << endl;

To find: The output of the code and the flowchart of the code.

Solution:

The output of the code will be nothing. The first ‘if’ statement will be executed as 3 > 2 will be true...

(b)

Explanation of Solution

Given: The value of x is 3, of y is 4, and the following expression:

if (x > 2)

{

if (y > 2)

{

int z = x + y;

cout << "z is " << z << endl;

}

}

else

cout << "x is " << x << endl;

To find: The output of the code and the flowchart for the code.

Solution:

The output of the code will be “z is 7�. The first ‘if’ statement will be true because 3 > 2, and the first ‘if’ statement will be executed...

(c)

Explanation of Solution

Given: The value of x is 2, of y is 2, and the following expression:

if (x > 2)

{

if (y > 2)

{

int z = x + y;

cout << "z is " << z << endl;

}

}

else

cout << "x is " << x << endl;

To find: The output of the code and the flowchart for the code.

Solution:

The output of the code will be “x is 2�. The first ‘if’ statement will be false because 2 is not greater than 2, the first ‘if’ statement will not be executed...
