#include <stdio.h> /* Enumeration or Enum in C is a special kind of data type defined by the user. It consists of constant integrals or integers that are given names by a user. The use of enum in C to name the integer values makes the entire program easy to learn, understand, and maintain by the same or even different programmer. Syntax to Define Enum in C An enum is defined by using the ‘enum’ keyword in C, and the use of a comma
