Is C/C++ language is still important in 2019?

Yes... IOS Apple phones OS is build in Objective C language .

major antivirus company uses c++ as main language for development ex. Quickheal.

C language is still at large a machine level language used by mainframe computers and in reasearch. 

I think Above examples are enough to highlight c/c++ importance in 2019.

Lets talk in terms of industries.

Below the high level languages, everything is written in C. Operating systems, drivers, stacks, run time environment, virtual machines and etc are completely based on C. The whole IT industry runs on C in the background. Maybe 2009 or 2019, Every language is powered by C.

In embedded computing the dependence is much more deep. For low-end microcontrollers it’s 100%powered by C, not counting assembler and direct binary machine code, which are hardly used as the main language for big projects. For many MCU’s(micro controller units) there is no alternative, C is the only supported language.

 It's reasonable level of abstraction, making it useful for all ranges of tasks from “portable assembler” to high level application development makes it a unique combination for any application. It’s probably the most important language and will continue to be that for the foreseeable future.

It's essential if you work in products/areas based on C/C++.
If you are a student, anyone language is sufficient, be it C/C++ or Java. If it's object-oriented like C++ or java, it is better.
Otherwise, you will be judged by your programming skills (be it any language.). Be confident that if you can write code in one language, then you will be able to write code in any other language too. It's just a matter of time.

Programming skills are more important than the language part.
