Question

Chapter 5, Problem 1TF

(a)

Program Plan Intro

To verify whether the given statement is true or false.

(a)

Expert Solution

Program Description Answer

True.

Explanation of Solution

Explanation:

A loop is a control structure that causes certain statements to execute repeatedly until a certain condition is met. This is the definition of a loop. Examples of a loop are for loop, do-while loop.

Conclusion:

Hence, the given condition is true.

(b)

Program Plan Intro

To verify whether the given statement is true or false.

(b)

Expert Solution

Program Description Answer

False.

Explanation of Solution

Given statement:

Explanation:

While loop is a loop that is used to perform repeated operations. In a counter-controlled while loop, it is essential to initialize the value of loop control variable, otherwise, the loop will behave in an undefined manner. To start the loop an initial value is always required that acts as a starting point of the loop.

Conclusion:

Hence, the given condition is false.

(c)

Program Plan Intro

To verify whether the given statement is true or false.

(c)

Expert Solution

Program Description Answer

True.

Explanation of Solution

Explanation:

In a while loop, the loop body is executed repeatedly as long as the condition specified in the loop header is true. However, if the condition is initially false, the loop body will not be executed at all. This is because the loop body is only executed when the condition is true. If the condition is false from the beginning, the loop will not execute at all, and the program control will move on to the next statement after the loop.

Conclusion:

Hence, the given condition is true.

(d)

Program Plan Intro

To verify whether the given statement is true or false.

(d)

Expert Solution

Program Description Answer

False.

Explanation of Solution

Explanation:

In an infinite while loop, the while expression is always true from the beginning and remains true throughout the execution of the loop. This is because the loop is designed to execute indefinitely, and no condition could cause the loop to terminate.

Conclusion:

Hence, the given condition is false.

(e)

Program Plan Intro

To verify whether the given statement is true or false.

(e)

Expert Solution

Program Description Answer

True.

Explanation of Solution

Given statement:

The while loop:

j=0;

while (j<=10)

j++;

terminates if j>10.

Explanation:

The while loop as given in the question will exit until j is no longer less than or equal to 10. When j is equal to 11, the loop terminates.

Conclusion:

Therefore, the statement "The while loop terminates if j > 10" is true.

(f)

Program Plan Intro

To verify whether the given statement is true or false.

(f)

Expert Solution

Program Description Answer

True.

Explanation of Solution

Explanation:

A sentinel-controlled while loop is a type of event-controlled while loop that is used when we want to read a sequence of data items from an input stream, such as a keyboard or file input. The loop continues until a special value called a sentinel value is encountered, which signals the end of the input and causes the loop to terminate.

Conclusion:

Hence, the given condition is true.

(g)

Program Plan Intro

To verify whether the given statement is true or false.

(g)

Expert Solution

Program Description Answer

True.

Explanation of Solution

Explanation:

The data can be input either from the console or read from the file. While reading from the file, if the length of the file is specified then reading from it becomes easy. But, if the length of the file is not specified then an EOF (End of File)-controlled loop is a good choice for reading data from a file because it will continue reading until it reaches the end of the file and stops once the end is reached.

Conclusion:

Hence, the given condition is true.

(h)

Program Plan Intro

To verify whether the given statement is true or false.

(h)

Expert Solution

Program Description Answer

False.

Explanation of Solution

Explanation:

When a while loop terminates, the program control goes directly to the statement immediately following the while loop and does not go back to the statement just before the while loop. Going back to the previous statement is always performed by using the go to statement.

Conclusion:

Hence, the given condition is false.

(i)

Program Plan Intro

To verify whether the given statement is true or false.

(i)

Expert Solution

Program Description Answer

False.

Explanation of Solution

Explanation:

A do-while loop is called a post-test loop because the condition is tested at the end of the loop body after the loop has been executed at least once.

Conclusion:

Hence, the given condition is false.

(j)

Program Plan Intro

To verify whether the given statement is true or false.

(j)

Expert Solution

Program Description Answer

True.

Explanation of Solution

Explanation:

The break statement is used to exit a loop prematurely and executing a break statement in the body of a loop immediately terminates the loop.

Conclusion:

Hence, the given condition is false.

Answer 33

Explanation of Solution

Explanation:

In an infinite while loop, the while expression is always true from the beginning and remains true throughout the execution of the loop. This is because the loop is designed to execute indefinitely, and no condition could cause the loop to terminate.

Conclusion:

Hence, the given condition is false.

(e)

Expert Solution

Program Description Answer

True.

Explanation of Solution

Given statement:

The while loop:

j=0;

while (j<=10)

j++;

terminates if j>10.

Explanation:

The while loop as given in the question will exit until j is no longer less than or equal to 10. When j is equal to 11, the loop terminates.

Conclusion:

Therefore, the statement "The while loop terminates if j > 10" is true.

(f)

Expert Solution

Program Description Answer

True.

Explanation of Solution

Explanation:

A sentinel-controlled while loop is a type of event-controlled while loop that is used when we want to read a sequence of data items from an input stream, such as a keyboard or file input. The loop continues until a special value called a sentinel value is encountered, which signals the end of the input and causes the loop to terminate.

Conclusion:

Hence, the given condition is true.

Answer 48

(g)

Program Plan Intro

To verify whether the given statement is true or false.

(g)

Expert Solution

Program Description Answer

True.

Explanation of Solution

Explanation:

The data can be input either from the console or read from the file. While reading from the file, if the length of the file is specified then reading from it becomes easy. But, if the length of the file is not specified then an EOF (End of File)-controlled loop is a good choice for reading data from a file because it will continue reading until it reaches the end of the file and stops once the end is reached.

Conclusion:

Hence, the given condition is true.

(h)

Program Plan Intro

To verify whether the given statement is true or false.

(h)

Expert Solution

Program Description Answer

False.

Explanation of Solution

Explanation:

When a while loop terminates, the program control goes directly to the statement immediately following the while loop and does not go back to the statement just before the while loop. Going back to the previous statement is always performed by using the go to statement.

Conclusion:

Hence, the given condition is false.
