Download EditPlus from
here. You can install this on
your own laptop to use for editing programs. Alternatively, in the
labs you can use TextPad (Start->Programs->Textpad) for the same
function. |
|
2. |
You can download the compiler
here
- click on compiler (a description of the setup is
here). Please note that although the compiler is for C++, we
will be using it for C - a subset of the C++ programming
language.
The compiler is the special program that will convert your
source code, written in the C (note NOT C++) programming
language from source code into executable code.

To avoid getting certain errors over the course of
this module, you must download
this file and save it to c:\borland\bcc55\bin (Right Click ->
Save As) in your own installation. This is not necessary if you are
just using the installation in DIT. |
|
4. |
Please note that this will install your compiler in a
folder named c:\borland\bcc55\, so when you are setting the path
environment variable in your programming tasks, please use the
following command:
set PATH=%PATH%;C:\Borland\BCC55\Bin
This is in contrast to the set-up in the computer labs, where the
compiler is installed in the c:\bcc55 folder, so in the labs you
need to set the path as follows:
set PATH=%PATH%;C:\BCC55\Bin
As a shortcut, you can download the batch file
here (right-click and save-as). Then,
whenever you want to use your compiler, you can copy this file to
the directory your code (.c files) is in, and execute as follows:
If you are in college, you can set your path from the command
line in the folder where the code is located by typing
set_my_path DIT
If you are at home, and you've installed your compiler into c:\borland\bcc55
(as occurs by default), then you can set your path from the command
line in the folder where the code is located by typing
set_my_path HOME

Running your Programs
|
|
5. |
Create a folder on your u: drive called programming.
Note that if you are using your own laptop you should set up this
folder on the c: drive. However, in order for me to see your
programs, you must copy them to the u: drive in college at regular
intervals. Your lab supervisor will help you with this.
Create a subfolder in programming named week_1.
Download paa_01_01.c (Right click ->
Save As...) and put it in week_1.
|
|
6. |
Open a command prompt (Start -> Run -> type cmd). The
command prompt provides you with a way to issue instructions to your
operating system. In this case, we're going navigate the file system
and tell the operating system to use the compiler program to convert
our source code to executable code (this isn't even half as
difficult as it sounds).
Change to your week_1 folder using the following commands:
u:
cd \
cd programming
cd week_1
|
|
7. |
Execute the following command:
set PATH=%PATH%;C:\BCC55\Bin
Remember, if you're doing this at home, use:
set PATH=%PATH%;C:\borland\BCC55\Bin
or use the batch file from step 4 as a short cut by typing
set_my_path DIT
(Note that to use the batch file, the file will need to be in the
same folder as your command prompt.)
|
|
8. |
Compile your program using the following command:
bcc32 paa_01_01.c
This will create a file named
paa_01_01.exe
This is an executable file containing executable code for the
Windows platform.
You can execute the program by typing
paa_01_01.exe
or simply
paa_01_01
|
|
9. |
Download, compile and run each of the following
programs:
|
|
10. |
Write a simple program which asks the user to enter 10
numbers and then prints out their average (+ is the addition
operator, / is the division operator).
Don't worry if you find this difficult - we will be going into a
lot more detail in the future weeks.
See samples solutions here and
here.

|
11. |
To avoid getting some of the compiler errors you may
be getting, you should do the following:
When compiling your code, you should provide a -P switch, which
will allow your code to compile.
e.g.
bcc32 -P paa_09_12.c
Alternatively, you can edit the file bcc32.cfg in your borland\bin
folder, and simply add in a line containing -P.
