Hi im new in need of help!

Hi everyone! Im new at his forum and I need some help with this assignmnent I have! Just so you have an idea, I am NOT a computer science major...and I have no idea of what Im doing so help is appreciated!

My assignment is the "Diamond" assignment and I already have the code done! but one last thing i have to do... to write a class. To be more specific.. ''
Write a class called Diamond. Have the appropriate data members for that class. Also have a constructor and a function to output the diamond."

This is my code in .cpp

Code:

 
#pragma once 

class Diamond
{
public:
	Diamond(void);	
	~Diamond(void);
};

#include "stdafx.h"
#include<iostream>
using namespace std;

int main(){
int n,i,j; //integer
char symbol; //character
cout<<"Enter the character, and length: ";
cin>>symbol;

cin>>n;
if(n %2 ==0 || n<0 || n >21) // indicates the number has to be even, greater than 0 and less than 21
{
     do{
            cout<<"You have entered an illegal value for the length.  It must be between 1 and 21.";
            cin>>n;
            }
	 while(n %2 ==0 || n<0 || n >21); // the do will run if this condition is followed
 }
 for(i=0;i<n/2;i++) // range for the loop
	                  // number of rows divided by 2 and increased by 1
 {
  for(j=n/2-i;j>=0;j--)
  cout<<" "; // output blank space
  cout<<symbol; // output character intered
  for(j=1;j<=2*i;j++)
  cout<<" ";
  if(i>0)
  cout<<symbol;
  cout<<endl;
 }
 for(i=n/2;i>=0;i--)
 {
  for(j=n/2-i;j>=0;j--)
  cout<<" ";
  cout<<symbol;
  for(j=1;j<=2*i;j++)
  cout<<" ";
  if(i>0)
  cout<<symbol;
  cout<<endl;
 }

system("pause");
}

I suck at classes.... any idea on how to do it?
Thank you!

Mention what problem you ar facing in the above code?

thanks for replying! my problem is that I dont know how to write the class. Im pretty sure the code I have there is not enough because I have to assign data members.

how to I assign them if all I have is int n,i, j, and char symbol.

I get confused because in a previewous class assignment I had to add the class and have 3 files, one .h, one .cpp and another .cpp (main)

some GUIDANCE would really help!

Thank you

Read this

thanks for the link.

in this case, with the loops, could you please give me an example? and should the constructor be in the .h file and the loops be in the .cpp or everything together?

thank you for helping i am extremely confused and frustrated

Place all of the function definitions in header file (.h)...
All the implementation of header files in .cpp file
And remaining main from the main.cpp or any_Name.cpp...
Also read this......
You must read this...

This is what I have so far in the .h file... what am i missing?

Code:

#pragma once

#include <iostream>
using namespace std;
using std::endl;
using std::cout; 

class Diamond5
{
	int n,i,j;
	char symbol
public:
	Diamond5(void);

	~Diamond5(void);
};

This is what I have so far in the .h file... what am i missing?

Write a class called Diamond. Have the appropriate data members for that class. Also have a constructor and a function to output the diamond

I don't see a function to output the diamond.

Jim

im sorry to ask this but how you please help me or guide me to create this class?? how to I do it with the loops??? im trying to do it using a template of a previous class assignment but i dont know how to do it

I shared the links... You must read them carefully...

You must not use "using namespace std" in header files.

ok this is whay i have so far and thank you guys for the help. this is the ONLY error i get

.h - header file

Code:

#pragma once

#include <iostream>

using std::endl;
using std::cout; 

class Diamond5
{
private:  int lengthN;
		  int lengthI;
		  int lengthJ;
	      char symbol;
public:
	Diamond5(void);
	int getLengthN ();
	int getLengthI ();
	int getLengthJ ();
	char getSymbol ();
	~Diamond5(void);
public: Diamond5 (int, char);
public: void printInfo ();
		void setLengthN (int);
		void setLengthI (int);
		void setLengthJ (int);
		void setSymbol (char);
}; // end of class definition

and this is the .ccp (not main)

Code:

#include "StdAfx.h"
#include "Diamond5.h"

Diamond5::Diamond5(int n, int i, int j, char s) // constructor that initializes the values of the data members
{
	lengthN = n;
	lengthI = i;
    lengthJ = j;
	symbol = s;
}
void Diamond5::printInfo(){
	cout << "Enter the character and lenght: " << symbol << endl;
	cout << "You have entered an illegal value for the length.  It must be between 1 and 21." << lengthN << endl;
}
Diamond5::~Diamond5(void)
{
}

Diamond5::Diamond5(void)
{

}
void Diamond5::setLengthN (int n)
{
	lengthN = n;
}
void Diamond5::setLengthI (int i)
{
	lengthI = i;
}
void Diamond5::setLengthJ (int j)
{
	lengthJ = j;
}
void Diamond5::setSymbol (char s)
{
	symbol = s;
}
int Diamond5::getLengthN(){
	return lengthN;
}
int Diamond5::getLengthI(){
	return lengthI;
}
int Diamond5::getLengthJ(){
	return lengthJ;
}
char Diamond5::getSymbol(){
	return symbol;
};

THE ERROR IS : error C2511: 'Diamond5:iamond5(int,int,int,char)' : overloaded member function not found in 'Diamond5'

THANK U SO MUCH!
[code]

Sort out your indentation, from a cursory glance it seems you have two different definitions for your constructor.., well you dont have two, you have one, and a call that requires a different definition that does not exist hence the message

I'm sorry if I'm reposting bur I thought I did n is not showing... So here I go again... My problem is the member function n te header definitions.. .
This is really frustrating but I'm sure it's very simple can somene please show me what changes to make!?!

Thank u very much
