Installing dos.h in Ubuntu [duplicate]

While graphics.h offers user-friendly graphical functions, it is no longer recommended or supported. Additionally, open-source C++ compilers typically do not provide support for conio.h, which is primarily utilized in Borland compilers. As a solution, it is worth noting that graphics.h is an outdated Borland C++ header file for graphics in the Ms DOS operating system.

Question:

.

I am currently using Ubuntu 16.04


Solution:
