Lab
1 : PC and C++ Basics
If you have trouble with any of the below steps, please raise your hand during the lab and the TA will help.
1. Use Netscape Communicator or Internet Explorer to access the comp104 webpage. Open the lecture notes for the first class, and print them out. Print four slides per physical page to save paper and save print quota. To do this, after selecting "Print" from the "File" menu, hit the "Properties" button, then from the "Layout" tab hit the "Advanced..." button, set "Pages per sheet" to "4 (Landscape)", and hit "OK".
2. Access the comp104 newsgroup hkust.cs.class.104 through the comp104 webpage to see the latest postings.
3. Send an email to your TA that includes your name, email address, and lab section.
4. Follow the below "Basic Instructions in Writing Visual C++ Programs" to start and run VC++ on the following short program:
#include <iostream>
using namespace std;
int main(){
cout << "Hello world!" << endl;
cout << "Comp104 is great" <<endl;
return 0;
}
You can copy and paste the above program into a source file "lab1.cpp" in VC++.
5. Change the output string "hello world!" to your own message (e.g., "Hi Mom!" or "I am hungry!").
6. Also, delete the semicolon after the "endl" to see what error message appears when you compile the program. Also, how is the output different without "endl"?
cout << "hello world!";
7. Demo your working program for step 5 for your TA. If for some reason you cannot finish before the end of the lab period, email your program to your TA by Sunday 11 September 5PM (please include your name and lab section in the subject line of the email).
8. Close all your
applications
and Log Off.
Basic Instructions in Writing Visual C++ Programs
Start up Visual C++
Now you are ready to compile your program. If there are any syntax errors, error messages will be displayed in a window at the bottom of the screen. You should correct all the errors.
