Help with classes?

[bruno455]

cire, i'm having the same problem with a similar assignment. perhaps you could be more specific as to what you mean by defining the methods?

Thank you

[Shinigami]

//this is class definition
class Some
{
  public:
    //this is methods declaration
    void set();
    void get();
    //end of method declaration
};
//end of class definition

//this is methods definition
void Some::set()
{
  std::cout << "Hi" << std::endl;
}

void Some::get()
{
  std::cout << "I will get you!" << std::endl;
}
//end of method definition

thanks Shinigami. that helps a lot. but what if you're not just trying to output text? for instance, how would you initialize an array in the definition?

[Whovian]

Initializing an array or something of the sort in the definition of a class? That would involve constructors.

[Shinigami]

class Array
{
  public:
    Array();
  private:
    int array[10];
};

Array::Array()
{
  for (int i = 0; i < 10; i++)
  {
    array[i] = i;
  }
}

or

class Array
{
  public:
    Array();
  private:
    int array[10];
    void make_array();
};

Array::Array()
{
  make_array();
}

void Array::make_array()
{
  for (int i = 0; i < 10; i++)
  {
    array[i] = i;
  }
}

Thanks for all of your help.
I ended up figuring it out:

.h file:

#include <string>
using namespace std;
#ifndef bstore_H
#define bstore_H

class bstore
{
public:
	bstore();
	bstore(string);
	string title();
	string author();
	string price();
	
	
private:
	
	string name;
	string money;

	
};
#endif 

first cpp file:
#include "hw.h"
#include <string>
#include <iostream>
using namespace std;

bstore::bstore(){
}

string bstore::title()
{
	cout<<"Title of book: "<<endl;
	cin>> name;
	return name;
}
string bstore::author()
{ 
	cout<<"Name of Author: "<<endl;
	cin>> name;
	return name;
}
string bstore::price()
{ 
	cout<<"Cost of Book: "<<endl;
	cin>> money;
	return money;
}



main code:

#include "hw.h"
#include <string>
#include <iostream>
using namespace std;
string bookinfo[8][3];
string k;
int l;
string changes;
int main()
{
	bstore basicinfo;
		
	string basicinfotitle;
	string basicinfoauthor;
	string basicinfoprice;

	int j;
	for(j=0;j<7;j++){
		cout<<"book number "<<j<<endl;
	basicinfotitle=basicinfo.title();
	basicinfoauthor=basicinfo.author();
	basicinfoprice=basicinfo.price();
	
	bookinfo[j][0]=basicinfotitle;
	bookinfo[j][1]=basicinfoauthor;
	bookinfo[j][2]=basicinfoprice;
	
}
	string yesno;
	
	while(yesno!="q"){
cout<<"Type display to display a table of books. Type edit to edit a value."<<endl;	
cout<<"Enter q to quit at any time"<<endl;
cin>>yesno;

if(yesno=="display"){
	cout<<"book number"<<"\ttitle"<<"\tauthor"<<"\tprice"<<endl;
	cout<<" "<<endl;
	for(j=0;j<7;j++){
	cout<<j<<"\t\t"<<bookinfo[j][0]<<"\t"<<bookinfo[j][1]<<"\t"<<bookinfo[j][2]<<endl;
	
	}
}

if(yesno=="edit"){
cout<<"Which book would you like to edit?" <<endl;
cin>>j;
cout<<"Which part would you like to edit?(Enter T,A or M)"<<endl;
cin>>k;
if(k=="T"){
l=0;
}
else if(k=="A"){
l=1;
}
else if(k=="P"){
l=2;
}

cout<<"Make changes: "<<endl;
cin>> basicinfotitle;
bookinfo[j][l]=basicinfotitle;
cout<<bookinfo[j][l];
	}
	}

}

(Sorry, I put all three documents into the same code block above but you should be able to figure it out . one is a .h one is first .cpp file and the last main code )
