So here I am trying to make a little practice (very limited) string class when all of the sudden my code won't compile, what a bi*ch huh? Well Please help.

#include <iostream.h>
#include <stdlib.h>
#include <string.h>
// here I was just starting my very limited string class and
//all of the suddem THIS!!!!!! won't compile, help.
//limited string class, just for practice
class String
{
public:
String();

int Getlength(); //error
int Get string();

private:
int length;
int *string;
};

String::Get String() //error
{
return *string;
}

int main()
{

system("PAUSE");
return 0;
}

//I was just beginning this little round of coding, as you can see I am really a newbie, and though that creating my own string class will really help a lot since it involves a lot of what C++ it's all about.

//PS DON'T MAKE FUN OF ME, oh wait yes go ahead and laugh away

ok I got those fixed but now I can more errors (so this is how microsoft felt after releasing Win ME, tries to update 98 and ends up making the mess a bigger.)

**incognito** · 01-27-2002

#include <iostream>
#include <stdlib.h>
#include <string.h>
using namespace std;

//limited string class, just for practice
class String
{
public:
String();

int Getlength();
int Getstring();

private:
int length;
int *string;
};

String::Getstring()
{
return *string;
}

int main()
{

system("PAUSE");
return 0;
}

/*I get this error "31 c:\docume~1\incogn~1\desktop\limite~1.cpp
ANSI C++ forbids declaration `Getstring' with no type" */

Please anybody out there?

Code:

String::Getstring() 
{ 
return *string; 
}

is wrong. it should be this:

Code:

int* String::Getstring() 
{ 
return string;  /* edited for error */
}

and the declararion should be this:
int* Getstring();

I usually use strings that are of type char but that's just me.

Why should it have a (*) on it?

**incognito** · 01-27-2002

Oh because you're returning a reference of a string so it can be displayed? Am I close, well correct me.

**taylorguitarman** · 01-27-2002

Because that is the type you declared it as. The return value just has to match the type of whatever you are returning.

Sorry I meant:

Code:

int* String::Getstring()
{
 return string;
}

the variable doesn't have to have the * just the return type.
it's late.

Ok, I got it to compiler now......Thanks.......I'll keep on working on it tomorrow (man if you just read books and don't practice you're screwed, I am finding this the hard way, now I am having problems creating a simple string class).

Code:

const char *String::Getstring()
{
return  string;
}

So is this telling the computer to return the string as a constant reference? In turn returning the string?

Code:

#include <iostream> 
#include <stdlib.h> 
#include <string.h> 
using namespace std; 

//limited string class, just for practice 
class String 
{ 
public: 
String(); 

int Getlength(); //error 
char *Getstring(); 

private: 
int length; 
char *string; 

}; 


char* String::Getstring() 
{ 
return string; 
} 

int main() 
{ 

system("PAUSE"); 
return 0; 
}

this compiles. you're very close but still not getting a few concepts. keep it up though

Yeah thanks it compiled. Somehow my post telling you that I got it to compile didn't show up I guess because I see it but can't edit it.
