Program Plan Intro

A)

Enumeration:

Enumeration is a user-defined data type which consists of enumerators; the enumerators are used to represent integer constants.

  • An enumeration can be defined by using the keyword “enum”.
  • By default, the values of enumeration type are filled with “0” to “n” sequentially and those default values can be changed when declaring the enumeration.
    • In a sequence of enumerators, if the first enumerator is assigned with a “user-defined value” and the next enumerator is not assigned with any value, then by default the next enumerator will be filled by the value “user-defined value of previous enumerator plus 1”.
  • The type name of an enumeration is optional; if name of the enumeration type is not given then it is referred as “anonymous”.

Syntax:

Syntax to declare an enumerated data type is as follows,

enum type_name {identifier_1, identifier_2, identifier_3, … identifier_n};

In the above syntax,

  • “enum” is the keyword used to declare an enumerator.
  • “type_name” refers the name of the type of the enumerator.

“identier_1” to “identifier_n” are refers the list of the identifiers declared in the enumerator.

Given statement:

enum Department {Purchasing, Manufacturing, Warehouse, Sales};

Department floor1, floor2;

int dNum = 2;

  • Here, an “enum” is a keyword and “Department” is the variable name of an enumeration. “Purchasing”, “Manufacturing”, “Warehouse” and “Sales” are the values used in the enumeration.
  • The variable name “floor1” and “floor2” of type “Department” is defined. These two variables can only store any one of the four values (Purchasing, Manufacturing, Warehouse, Sales).
  • “Purchasing”, “Manufacturing”, “Warehouse” and “Sales” are treated as integers by complier.
  • Once enumerators are defined, their value cannot be changed in program.

struct namerec{ char last[15]; char first[15]; char middle[15]; }; struct payrecord{ int id; struct namerec name; float hours, rate; float regular, overtime; float gross, tax_withheld, net; Given the above declaration, let payroll data record be stored in a structure called payrecord. Also define a type called payrecord for the structure data type that houses a payroll data record: typedef struct payrecord payrecord; This program reads data, computes payroll and prints it. Each data record is a structure, and the payroll is an array of structures. Overtime hours are 150% of the rate. (Note: Maximum regular hours for the week is 40.) Tax is withheld 15% if weekly pay is below 500, 28% if pay is below 1000, and 33% otherwise. A summary report prints the total gross pay and tax withheld.
