Hello World

Group: Captain: Recorder: Reflector:

Motivation

Some problems are best addressed using computer programs. Learning how to compile and run a program will make you a more well-rounded engineer.

Objectives

1.

Access the computer.

2.

Access the C++ compiler.

3.

Locate the help facility.

4.

Write a basic program that writes ``Hello World'' on the screen.

5.

Experiment with the program.

6.

E-mail the program to your instructor and the group.

Performance Criteria

1.

Production of the message. (60%)

2.

Success in E-mailing your program to your instructor and the reflector. (10%)

3.

The knowledge demonstrated by your definitions of the vocabulary. (10%)

4.

The depth of understanding demonstrated by your answers to the critical thinking questions. (20%)

Resources

1.

The textbook, especially ``Creating Your First Program'' and ``Taking a Closer Look at C++''.

2.

The online help facilities of windows and the compiler.

Plan

1.

Follow the instructions given.

2.

See what vocabulary you can define.

3.

See what critical thinking questions you can answer.

4.

Take the test and submit it.

Vocabulary

Select the best answer:

1.

Interactive:

(a)

The computer acts upon your instructions

(b)

The computer immediately reponds to your actions

2.

Program source:

(a)

A set of commands you want to give to the computer. Probably found in a .cpp file if you use C++.

(b)

Translating commands into a language the computer's Central Processing Unit (CPU) can understand. Ordinarily produces object (.obj) files.

(c)

The process of combining object files into an file that the computers's CPU can execute. Ordinarily produces am executable (.exe) file.

(d)

The complete process of converting a program source into an file that the computers's CPU can execute. Typically produces a .exe file as the final result from one or more .cpp and header (.h) files.

3.

Compile:

(a)

A set of commands you want to give to the computer. Probably found in a .cpp file if you use C++.

(b)

Translating commands into a language the computer's Central Processing Unit (CPU) can understand. Ordinarily produces object (.obj) files.

(c)

The process of combining object files into an file that the computers's CPU can execute. Ordinarily produces am executable (.exe) file.

(d)

The complete process of converting a program source into an file that the computers's CPU can execute. Typically produces a .exe file as the final result from one or more .cpp and header (.h) files.

4.

Link:

(a)

A set of commands you want to give to the computer. Probably found in a .cpp file if you use C++.

(b)

Translating commands into a language the computer's Central Processing Unit (CPU) can understand. Ordinarily produces object (.obj) files.

(c)

The process of combining object files into an file that the computers's CPU can execute. Ordinarily produces am executable (.exe) file.

(d)

The complete process of converting a program source into an file that the computers's CPU can execute. Typically produces a .exe file as the final result from one or more .cpp and header (.h) files.

5.

Build:

(a)

A set of commands you want to give to the computer. Probably found in a .cpp file if you use C++.

(b)

Translating commands into a language the computer's Central Processing Unit (CPU) can understand. Ordinarily produces object (.obj) files.

(c)

The process of combining object files into an file that the computers's CPU can execute. Ordinarily produces am executable (.exe) file.

(d)

The complete process of converting a program source into an file that the computers's CPU can execute. Typically produces a .exe file as the final result from one or more .cpp and header (.h) files.

6.

Bug:

(a)

A mistake that causes the program not to run.

(b)

A mistake that causes the program not to run correctly.

7.

Execute:

(a)

Having the CPU compile the .cpp file

(b)

Having the CPU execute the .exe file
