General Purpose Language with Object-Oriented Programming, and Powerful Data Structure and Algorithms
SpecsUpdate
Pros
Pro Excellent compiler optimization
Both open source compilers (such as Clang and GCC), and proprietary ones (like Intel's and Microsoft's) are very good at analyzing program flow and program optimization. This is mostly due to the widespread usage of C/C++ applications running everything from mobile/desktop/server Operating Systems, to search engines and webserver software, and the demand for performance.
Pro Teaches problem solving
The great STL is the most powerful Data Structure and Algorithms Library. It would benefit you very much in problem solving, your main way to love programming. The code is much compact compared to Java and C#. No unnecessary classes are in your way; yet when you need classes they are available unlike C. The code runs very fast.
Cons
Con Memory leaks and segmentation faults
Because C and C++ allow the user direct access to memory and don't provide garbage collection threads, there is a probability that a program may have a "memory leak", which occurs when something a programmer allocated in the heap is not deallocated properly. Also, attempting to dereference memory protected by the operating system causes a segmentation fault and kills the program.
Con C++ succombs under its own weight
The years of cramped backward compatibility start to show in the syntax, complexity and very top-heavy language structures. Trying to keep up with far more elegant languages like C# doesn't do C++ any good either, because the committee always seems to be able to mess it up. After numerous years, still no modules... you must be kidding!
Con Module system is not great
C++ uses the #include
mechanism provided by C. Which unfortunately is a poor way of accessing the API of a library. Some of the reasons why the module system is weak are:
Compile time scalability: The compiler must preprocess every header included in a file, and every header included in those headers. This process must be repeated for every translation unit in the program. As can be imagined, this doesn't scale very well. For each header added you are increasing the compilation time exponentially.
Fragile: modules included are treated as textual imports by the compiler. This causes all sorts of problems since they are subject to any macro definitions in the time of the inclusion. If any of these macro definitions collide with a name in the library it can break the library API .
Con Undefined behaviors and weak limited type safety
Undefined behavior in a program can cause unexpected results, making it hard to debug. With UB, program behavior may vary wildly depending on optimization settings. There are many cases that invoke UB, such as signed overflow, invalid dereferences, large integer shifts, uninitialized variables, etc. C++ allows for non-type safe operations such as logic errors, wild pointers, buffer overflow, etc. UB and type safety issues create a large number of bugs and security vulnerabilities.
Con Undefined behavior
Subtle errors can render the entire program "undefined" by the complicated C++ standard. The standard imposes no requirements in such cases. Thus C++ compiler writers are free to ignore the existence of such cases and Bad Things are prone to happen instead. Even experts can't reliably avoid undefined cases in C++, so how can beginners be expected to do so?
Con Suffers from fundamental design flaws of C and older C++ specifications
Due to attempting to be fully backward compatible, it continues to implement features on top of broken implementations of past concepts. In example, lack of type safety, poor memory management, lack of unit testing, lack of modules, and has the same fundamental problem of header files.
