Why c language is powerful?

C++ is general-purpose and portable, which is common to many high-level languages, but it Excels in terms of performance, comparable to that of assembly language. This is not surprising given the amount of work that goes into optimising the native machine code that the C++ compiler produces.

Java is arguably more popular today (especially with amateur programmers), but it doesn't perform well when compared to C++. This is largely due to the much higher level of abstraction which requires compiled programs to be executed and interpreted by the Java virtual machine. The main advantage of Java is that the abstraction allows Java programs to be run on any platform that supports the JVM without the need to modify the source code and recompile, which is the main disadvantage of C++. However, in terms of performance alone, few languages can compete with C++, hence its huge popularity in the community.
