Write your question here.

 #include "person.h"
#include "dateType.h"
class personalInfo
{
public:
	void setpersonalInfo(string first, string last,
						 int month, int day,
						 int year, int ID);
 	//Function to set the personal information.
 	//Data members are set according to the parameters
 	//Postcondition: firstName = first;
 	//   lastName = last; dMonth = month;
 	//   dDay = day; dYear = year; personID = ID;

 	void printpersonalInfo() const;
 		//Function to print the personal information.
	personalInfoType(string first = " ", string last = " ",
					 int month = 1, int day = 1,
					 int year = 1900, int ID = 0);
		//constructor
		//Data members are set according to the parameters
		//Postcondition: firstName = first;
		//	 lastName = last; dMonth = month;
		//   dDay = day, dYear = year; personID = ID
private:
	personType name;
	dateType bDay;
	int personID;
};

when I compile I get this error:
C:\Martin\MalikChapter2\clockInheritance\person\personalIntoType.cpp:19:34: error: ISO C++ forbids declaration of 'personalInfoType' with no type [-fpermissive]

please help

Your constructor should have EXACTLY the same name as the class.
personalInfoType
is NOT the same as
personalInfo

If it's another book/edition, perhaps it's noted in errata. 1st edition maybe?

Thank you all!!!
I changed personalInfo to personalInfoType and the error disappeared.
