//Implmentation
#include "first.h"
#include <iostream>
using namespace std;

first::first(char n[])
{
	strcpy(fName,n);
}

void first::setName(char n[])
{
	for (int i=0;i<20;i++)
		fName[i] = n[i];
}

char* first::getName()
{
	return fName;
}

First.h

(Toggle Plain Text)

ifndef H_First
#define H_First

class first
{
public:
	first(char[]);
	char* getName();
	void setName(char[]);
private:
	char fName[20];
}
#endif

#include "first.h"
#include <iostream>

using namespace std;

int main()
{
	
	first MyName("Mansoor");
 
	char* TheName = MyName.getName();


	cout << "n " << TheName << endl;

	return 0;

}

I dont see sal.h inclusion anywhere, coud someone check this code by compiling and see if they get the same error. I am guess could be some kind of setting problem perhaps,....

I think i read the rules but i forgot,... because I learned that code tag thingy from there,,.... anyway will be careful next time,..

Apart from the missing semi-colon at the end of class first everything looks fine.

Mack1982 · May 23rd, 2006, 11:25 PM

Are u sure there should be a semi colon after the class First,..
u mean like this,..

(Toggle Plain Text)

class first;
{
 public:

niteice · May 23rd, 2006, 11:35 PM

No, he means

(Toggle Plain Text)

class First
{
/* your class here */
};

Note the semicolon after the closing brace.

As for sal.h, it's used internally by most headers shipped with Visual C++.

Mack1982 · May 24th, 2006, 1:26 AM

Bingo man,.. U were right,.. the ; was the problem,.. it is fine now,..
But even then a very strange error for missing a ;

DaWei · May 24th, 2006, 6:50 AM

Yes, that is strange, the message, "missing ;" for a missing ;.

Ok the final part of the project which is a little trouble some,..

lets say that the following is the way a MAIN looks:

(Toggle Plain Text)

#include<iostream>
#include "employee.h" 
#include "List.h" //a link list class

Now lets say i make a list object called "MyList"

(Toggle Plain Text)

list myList();

How do i add five employee objects to the list
the list has the following functions:

(Toggle Plain Text)

class List
{
	Node* first;
	int count;
public:
	List();
	bool insert(Employee& s);	
	int size();
	void display();
	Employee& operator[](int n);
~List();
	
};
]

I tried searching the book,.. but couldn't find an example,..
Thanks

How about a loop that runs five (or however many) times, then gracefully retires to the country for the summer?

Watch your terminology. In a C or a C++, that is not the way a MAIN looks. You must be from outta town.

Yeah, a loop is the way to go. And look into the standard, built in List library. It'll save you some time, and you won't have to worry about stuff going wrong with your list coding.
