Does every Operating System come with a Command Line Interpreter (CLI) or a Shell?
Every Mainstream operating system till date has an command line interface or a shell the reason being the immense number of task that can be performed by a command line interface if replaced by a graphical user interface would only make the operating system more complex and difficult to use.
So, yes every os has an command line interface but theoritically we can have an operating system without command line interface and only using graphical user interface for it.

Command line input In C++ it is possible to accept command line arguments. Command-line arguments are given after the name of a program in command-line operating systems like Linux and are passed in to the program from the operating system. To use command line arguments in the program, it must first understand the full declaration of the main function, which until now has accepted no arguments. In fact, main can accept two arguments: one argument is number of command line...
