What would be C++ limitations compared C language? [closed]

Answer 1

I hate programming in C++.

Answer 2

I use C++ with C programming for two reasons:

• vector and string to get the array memory management away from me
• strict type checking and casts to warn and/or catch allthe nuisances I would miss otherwise.

So it is C really borrowing a few c++ but using the c++ compiler as much as I can. As someone else says in the answers, I find now I am actually picking up more C++ this way and where C would be too involving, I use C++. Monitor/Lock using RAII is one of these I've used recently when dealing with multi-threaded programs and another similar construct to open/close files.

Answer 3

C++ simply isn't supported in some real-world environments, like low-level embedded systems. And there's a good reason for that: C easily good enough for such things, so why use something bigger?

Answer 4

If you work in an environment with two languages, you might use C for some performance critical low-level functions and a more functional/high level language like C#/Java for the business logic. If C++ code is usedfor these functions ,C-Wrappers are required for JNI/unmanaged code around and this makes things more complex than solely using C.

Answer 5

There are three reasons I can think of. One is that C is more suited for embedded systems, due to the small size of its binaries and the wider availability of C compilers on any system. The second is portability: C is a smaller language, and and ANSI C code will compile anywhere. It's easier to break portability in C++. The last one is the language itself. C++ is harder, and is most definitely a very poorly designed language. Torvalds gripes are reported above.

Answer 6

The most useful thing I found in C is the lack of namespaces and overloads: function and symbol names are unique identifiers. To find the places where these symbols are used you can just grep through the source code files and search results will shows the locations.

It's essential when wiring in a new feature or component to an old and tangled system.

You cannot do this easily in C++, without a sophisticated call graph building tool.
