Chapter 3, Problem 8CP

(a)

Explanation of Solution

Given: The values of the variable termed ‘number’ are 30 and 35, and the following expression:

if (number % 2 == 0)

cout << number << " is even." << endl;

cout << number << " is odd." << endl;

To find: The possible output of the code.

Solution:

When the value of the number is 30.

The possible outputs of the code can be “30 is even� and “30 is odd�. The condition in the ‘if’ statement will be true because (30 % 2 == 0) will be true. Therefore, the ‘if’ statement will be executed, and it will print the message “30 is even� on the console screen. After that, the third statement will also be executed because it is not written in any ‘if or else’ block...
