Anyone to fix this??

[gnwillix88]

//example of constructor
#include <iostream>
#include <string>
#include "simple.h"

class Simple{
string Mystring("This is what am testing");
public:
Simple ();
void const (string)
{
return Mystring;
}

};

Simple::Simple (string a) {
Mystring = a;
Cout << a ;
}

int main () {
//declaring objects
Simple a;
Simple ();
system("pause");
return 0;
}

There are so many errors with this that I can't even tell what it is you're trying to do.

Can you explain what you're going for?

[EAStudent]

what is inside simple.h??

[gnwillix88]

Just corrected some of the errors. simple.h is commeted. Am trying to pass the string: This is what am testing.
/example of constructor
#include <iostream>
#include <string>
//#include "simple.h"

class Simple{
string Mystring("This is what am testing");
public:
Simple ();
void const (string)
{
return Mystring;
}

};

Simple::Simple (string a) {
Mystring = a;
}

int main () {
//declaring objects
Simple a;
Simple ();
system("pause");
return 0;
}

[Disch]

where are you trying to pass the string to?

[EAStudent]

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

class Simple
{
	string Mystring;//("This is what am testing");

	public:
		Simple ();

		Simple::Simple (string a) 
		{
			Mystring = a;
		}

		string getString()
		{
			return Mystring;
		}

};

int main () 
{
	//declaring objects
	Simple a;
	Simple ();
	system("pause");
	return 0;
}

if u want to use string..
u should using namespace too..
then there are no const void..
const is only for a variable..

more over..
im not make ur program to work..
just correct the program as u ask..
u still needed to find a way to pass the text to mystring..

[gnwillix88]

This is where I am now,
ERROR: simple.cpp prototype for `Simple::Simple(std::string)' does not match any in class `Simple'

u're so close..gud luck bro..

[gnwillix88]

Something am not seeing.
#include <iostream>
#include <string>
using namespace std;

class Simple
{
string Mystring;
public:

Simple ();
Simple (string a);
string getString();
};

Simple::Simple (string a)
{
Mystring = a;
}

string Simple::getString()
{
return Mystring;
}


int main ()
{
string text("This is what am testing");
//declaring objects
Simple a;
a.getString();

system("pause");
return 0;
}

[gnwillix88]

Sorry some mistake.

ERROR: 31 text.cpp no matching function for call to `Simple::getString(std::string&)'

#include <iostream>

}

{
return Mystring;
}


int main ()
{
string text("This is what am testing");
//declaring objects
Simple a;
a.getString(text);

system("pause");
return 0;
}

[EAStudent]

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

class Simple
{
	string Mystring;
	public:

	Simple ();
	Simple (string a);
	string getString(); 
};

Simple::Simple (string a)

	Mystring = a;
}

string Simple::getString()

	//declaring objects
	Simple a(text);
	string something = a.getString();

	system("pause");
	return 0;
}

[EAStudent]

may be u want to do this..

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

class Simple
{
	string Mystring;
	public:

	Simple ();
	Simple (string a);
	string getString(); 
	void setText(string a);
};

Simple::Simple (string a) 
{
	Mystring = a;
}

void Simple::setText(string a)
{
	Mystring = a;
}

string Simple::getString()
{
	return Mystring;
}


int main () 
{
	string text("This is what am testing");
	//declaring objects
	Simple a;
	a.setText(text);
	string something = a.getString();

	system("pause");
	return 0;
}

[gnwillix88]

It looks perfect but returns an error:


[Linker error] undefined reference to `Simple::Simple()'

[1yR4jE8b]

In that code there is a declaration for a no argument constructor for the Simple class, but there is no code to implement it. Hence the "undefined reference" error.
