class definition Q

I am trying to constuct a class that will represent an employee. I believe my declaration matches the definition of the constructor. Why am I getting the below errors? why would they be invalid function declarations?

Code:

---

#include <iostream>
#include <iomanip>
using namespace std;


//class declaration
 
class Employee
{
 private:
  int idNum;
  float payRate;
  int maxHours;
 public:
  Employee (int = 45, float = 9.00, int = 40);
  void changeData (int, float, int);
  void displayData (int, float, int);
};
 
//class implementation section
Employee : : Employee (int id, float rate, int max) //unqualified-id before':' token
{
  idNum = id;
  payrate = rate;
  maxhours = max;
}
 
void Employee : : changeData (int id, float rate, int max) //invalid function declaration
{                                                                     
  idNum = id;
  payRate = rate;
  maxHours = max;
 
  return;
}
 
void Employee : : displayData()  ////invalid function declaration
{
  cout<< "The employee ID is ";
  cout<<  idNum  << '/'
      << "The employee pay is ";
          <<  payRate << '/'
          << "The employee maximum hours are ";
          <<  maxHours << '/'
          << endl;
   
return;

I am not 100% sure, but try taking the space out from between the two colons... '::' instead of ': :'

yeah, I already tried this and in numerous ways! lol
tks!!

ok, just tried it again to double check myself and I now have 6 errors instead of 3...so, I am sure that is not the problem...

Everything else looks ok, What other errors did it bring up?

The language is case-sensitive: payrate is not the same as payRate, maxhours is not the same as maxHours.

Function signatures are important:

Code:

---

  void displayData (int, float, int);

---

does not match

Code:

---

void Employee :: displayData()  ////invalid function declaration

---

Dang, I must need some sleep... did not even see that myself.....

And if you're going to break things into multiple lines, don't prematurely end the lines.

Code:

---

void Employee :: displayData(int idNum, float payRate, int maxHours)
{
  cout<< "The employee ID is ";
  cout<<  idNum  << '/'
  << "The employee pay is ";
  <<  payRate << '/'
  << "The employee maximum hours are ";
  <<  maxHours << '/'
  << endl;

  return;   
}

yeah, it 'tis a bit late....
well I changed the case sensitive items (can't believe I missed those) and I will work on the functions. Back to more reading! Thanks !! ;)
