Convert an Enum to a String in C++

There are various methods to convert an enum to a string. A typical practice to convert an enum into a string is creating the mapping between values of enums and their string representations.

Approach

• Define an enum that represents a collection of related constants, assigning each constant a meaningful name.
• Use map to create a connection between enum values and their corresponding string representations.
• Establish a clear association between each enum value and its corresponding string by populating the mapping data structure.
• Develop a function that takes an enum value as input and returns its associated string by referencing the established mapping.
• Return the corresponding string from the function based on the enum parameter.
