Chapter 9, Problem 6SA

Explanation of Solution

Enumerated data type:

“Yes”, enumerators can be used in a loop to step through the elements in an array as they are used to represent the integer values.

• This is a programmer defined data type and the elements contained in it are also defined by the programmer or user.
• The elements are known as enumerators and represent the integer values.
• Declaration of enumerator has three parts as follows:
  • enum keyword
  • Enumerator name
  • List of identifiers
• When the identifiers are enclosed in braces, they are called enumerators and if they are enclosed in quotation marks, they are known as strings.
• Declaration:

enum Names{aa, bb, cc};

//declare the arrays

enum day{ Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday};

int[] score={10, 20, 30, 40, 50, 60, 70};

//create a text file
