Assigned Laboratory 1
Due Start of Laboratory 2

 Part I

• For the purposes of this homework, authorized help is any help received from your laboratory TAs, the instructor, or the ITC staff on the help desk.
• First bring up the Visual C++ compiler
• Open the program hello.cpp that you saved on your floppy disk from this week (or get another copy from the class website)
• Be sure that you have filled in the required header information (name, student ID, …, date).
• Note, this homework is pledged as follows
  • On my honor as a student of the University of Virginia, I have neither given nor received unauthorized help on this homework
• Type this exact statement after the colon on the line labeled //Honor pledge: and then type your name.
• Successfully build and run the program to be sure that it still runs. It should print the string Hello, World five times on five separate lines.
• Modify the program so that it displays five times Goodbye, World
• Successfully build and run the program.
• Modify the program so that it displays five times Welcome to CS 101, Homework 1
• Successfully build and run the program.
• Modify the program so that it only displays the message three times. Although we have not discussed in class how to do this, use your intuition and experiment.
• Successfully build and run the program
• Modify the program so that it displays the message ten times instead of three times.
• Successfully build and run the program.

Part II

• Currently the program displays Hit enter to finish. Modify the program so that instead displays Press the enter key to terminate the program
• Successfully build and run  the program.
• Delete your line
  • cout << endl << "Press the enter key to terminate the program" << endl;
• And replace it with
  • cout << "Press the enter key to terminate the program" << endl;
• Successfully build and run  the program and observe the formatting differences.
•  Replace the line
  • cout << "Welcome to CS 101, Homework 1" << endl;
• with the line
  • cout << endl << "Welcome to CS 101, Homework 1" << endl;
• Successfully build and run  the program and observe the formatting differences.

Part III

• Locate and remove the two lines
  • char reply;
  • cin.get(reply)
• Successfully build and run  the program  and observe the difference in the program's execution.
• Restore the two lines you just deleted
• Successfully build and run  the program  and observe the program and assure yourself that it operates as it did at the end of previous step.
• Print this final version of your source code.
• Review the printout of your source code. Be sure that all required header information is filled in, the honor pledge is typed, your name is typed and signed beside the honor pledge, and all lines of source code are present.
• On the honor pledge line of the printout where you have typed your name, sign your name.
