Students are presented with a detailed problem statement and guided through a simplified, UML-based object-oriented design process.
We have worked hard to produce a textbook and ancillaries that we hope you and your students will find valuable. The examples are also available for download at www. The file should be extracted into a separate directory e. The programs are separated into directories by chapter and exercise number. The Cyber Classroom helps students get more out of their courses. The Cyber Classroom is also useful for students who miss a lecture and have to catch up quickly. Instructor resources include textbook appendices e.
These lecture notes are available for instructors and students at no charge at our Web site www. We would sincerely appreciate your questions, comments, criticisms and corrections addressed to us at: deitel deitel. IV We will respond immediately. Please read the latest copy of the Deitel Buzz published every April and November for information on forthcoming Deitel publications, ancillaries, product options and ordering information.
Web site www. Our Computer Science editor, Petra Recter, worked closely with us to ensure the timely availability and professional quality of these ancillaries. Harvey M. Deitel Paul J. Why might a machine-dependent language be more appropriate for writing certain types of programs?
ANS: Machine independent languages are useful for writing programs to be executed on multiple computer platforms.
Machine dependent languages are appropriate for writing programs to be executed on a single platform. Machine dependent languages tend to exploit the efficiencies of a particular machine. ANS: input unit. ANS: computer programming. ANS: high-level language. ANS: output unit. ANS: memory unit and secondary storage unit. ANS: arithmetic and logical unit. ANS: machine language. ANS: central processing unit.
ANS: Object-oriented programming enables the programmer to build reusable software components that model items in the real world. Building software quickly, correctly, and economically has been an elusive goal in the software industry. The modular, object-oriented design and implementation approach has been found to increase productivity 10 to times over conventional programming languages while reducing development time, errors, and cost.
ANS: comments b The object used to print information on the screen is. ANS: if d Calculations are normally performed by statements. ANS: assignment e The object inputs values from the keyboard.
ANS: cin 1. If false, explain your answers. ANS: False. Some operators are evaluated from left to right, while other operators are evaluated right to left. ANS: True. All variables begin with an underscore or letter. The statement is an output statement. Arithmetic operators can appear in any order in an expression. Since multiplication, division, and modulus have higher precendence than addition and subtraction the statement cannot be true. ANS: division and modulus. ANS: innermost. ANS: variable.
Write the program using the following methods: a Using one output statement with one stream insertion operator. Use the constant value 3.
Do these calculations in output statements. Note: In this chapter, we have discussed only integer constants and variables.
In Chapter 3 we will discuss floating-point numbers, i. Use only the programming techniques you learned in this chapter. Hint: Use the modulus operator. An even number is a multiple of two.
Any multiple of two leaves a remainder of zero when divided by 2. Why might you prefer to experience a fatal error rather than a non—fatal error?
ANS: A fatal error causes a program to terminate prematurely. A nonfatal error occurs when the logic of the program is incorrect, and the program does not work properly. A fatal error is preferred for debugging purposes. A fatal error immediately lets you know there is a problem with the program, whereas a nonfatal error can be subtle and possibly go undetected.
In this chapter you learned about integers and the type int. When the preceding statement executes, it prints the value 65 on systems that use the ASCII character set. Write a program that prints the integer equivalents of some uppercase letters, lowercase letters, digits and special symbols. Hint: Use the integer division and modulus operators. ANS: Objects are composed in part by structured program pieces. ANS: 1 Determine which objects are needed to implement the system. ANS: Children. A child receives genes from both parents.
ANS: People send messages through body language, speech, writings, email, telephones, etc.
