Structures

Structure Definition
• Structure and Class definitions are contained in header files, and are #included in implementation files
• In C++ a structure can be defined in the following way:
  

  struct employee
  {
  	char name[25];
  	char job_code[10]
  	int date_of_birth;
  	float salary;
  };

• The above code specifies a new data type named employee, and specifies the components of the employee data type
• Note: The above code does not cause memory to be allocated. Therefore, it may be viewed as a declaration rather than a definition, even though many authors and books refer to this as a definition
• After the structure has been declared, variables of that data type may be defined similar to the manner in which variables of primitive data types are defined
• For example:
  employee Bill, SalesDept[25];
  defines a variable Bill and a 25 element array named SalesDept; both are employee data types
