What features make C plus plus so powerful?

Answer 1

When C++ was initially developed in 1978, it was unique in that there was no other language that incorporated object-oriented programming that could produce efficient machine code. Object-oriented programming languages did exist, of course, but the code they produced was often interpreted and therefore far too slow for anything but the most trivial of tasks. C++, like all object-oriented programming languages, is capable of solving highly-complex problems in a highly efficient manner, breaking larger problems down into smaller, simpler problems. But while newer languages such as Java and C# are just as capable as C++ and very much easier to program, they simply cannot match C++ in terms of performance. That remains unique to C++ today as it did when it was first released in 1985, and is the reason all major applications, including C++ compilers themselves, are still largely or wholly written in C++. The very first C++ compiler was written in C, of course.

Answer 2

C++ is an object oriented programming language. Hence it provides the user with the various OOPs facilities like

1) Encapsulation

2) Abstraction

3) Inheritance

4) Polymorphism

In addition to this, it also supports procedural programming and all the library functions of C language.

Answer 3

Large library, object oriented, built-in garbage collecter (I think), low processor usage, multi-threading, etc.
