Although the source
code in your file is somewhat cryptic, and anyone
who doesn’t know C++ will struggle to understand
what it is for, it is still in what we call human-readable
form. Your source code file is not a program, and
it can’t be executed, or run, as a program can.
To turn your source
code into a program, you use a compiler. How you
invoke your compiler, and how you tell it where
to find your source code, will vary from compiler
to compiler; check your documentation. In Borland’s
Turbo C++ you pick the RUN menu command or type
from the command
line, where <filename> is the name of your
source code file (for example, test.cpp). Other
compilers may do things slightly differently.
NOTE: If you compile the source code
from the operating system’s command line, you should
type the following:
|
For the Borland
C++ compiler:
bcc <filename>
For the Borland
C++ for Windows compiler: bcc <filename>
For the Borland
Turbo C++ compiler:
tc <filename>
For the Microsoft
compilers:
cl <filename>

After your source
code is compiled, an object file is produced.
This file is often named with the extension .OBJ.
This is still not an executable program, however.
To turn this into an executable program, you must
run your linker.
