C and C++ perceived common problems
pointers are dangerous
* memory leaks (failing to free memory correctly)
* function pointers (jumping to the wrong place)
+ data pointers (pointing to the wrong place)
manual garbage collection is a lot of work
multiple inheritance (C++) can get very complicated
* ambiguities like the “diamond problem” (a.k.a. “diamond of
death”)
not easily portable across platforms, even with re-compile
and discipline
جووه ,مه سه
صفحه 24:
a few ways Java improved on C++
instead of pointers, Java has references
* references are similar to pointers, but with protections
(cannot jump into illegal parts of memory)—avoids
segmentation fault problems
automatic garbage collection
* memory is reclaimed from the heap automatically—avoids
memory leaks
single inheritance
* avoiding the deadly diamond of death
encapsulation
* all code must be in a class—intended to encourage
information hiding
array bounds checking
libraries
* many common tasks already coded and available for “reuse”
by means of inheritance
* many interfaces (behaviors) already coded

سس جووه ,مه سه
صفحه 26:
Microsoft's big headache
* prior to .NET, Microsoft had a big headache
Microsoft was supporting too many operating systems
application programming interfaces (API's) were
implemented as dynamic link libraries (DLL's) develop using
C++
calling the Windows API was different on every operating
system
developers first had to find out exactly what kind of system
the program was running on
* and then determine if the API desired was actually installed on
the system
that doesn’t sound so bad
after all, there are only a few different kinds of Windows...
