Name Constants and Literal Values

A constant is a data item whose value cannot be modified throughout the program execution. When a constant is related to an identifier such as a variable, array, structure, or function, it is called a named constant. In most programming languages, the 'const' keyword is used to declare constants.

In this assignment, you will implement the shell “engine” as the “group” component, where all members are responsible for the following functionality: • A Command-Line Interpreter, or Shell Your shell should read the line from standard input (i.e., interactive mode) or a file (i.e., batch mode), parse the line with command and arguments, execute the command with arguments, and then prompt for more input (i.e., the shell prompt) when it has finished. 1. Interactive Mode In interactive mode, you will display a prompt (any string of your choosing) and the user of the shell will type in a command at the prompt.
Can someone help me answer this
What is a token? How does the shell decide where one token ends and other begins?
