C and C++ have a significant presence in the world of programming. Almost all low-level systems, such as operating systems and file systems, are written in C/C++. If you wish to be a system-level programmer, these are the programming languages that you should learn.
C++ is also widely used by competitive programmers owing to the fact that it is extremely fast and stable. It provides something called STL - Standard Template Library. This is a pool of ready-to-use libraries for various data structures, arithmetic operations, and algorithms. The library support and speed of the language make it a popular choice in the high-frequency trading community as well.
