Basic C++ programming help

[JDscar]

Hello, I'm getting this error
24 F:\ULTIMATE EXAMPLE PROGRAM.cpp new types may not be defined in a return type
24 F:\ULTIMATE EXAMPLE PROGRAM.cpp extraneous `int' ignored
24 F:\ULTIMATE EXAMPLE PROGRAM.cpp new types may not be defined in a return type

even when I return 0 and i don't know why. I'm using dev C++
#include <iostream>
#include <limits> //include for press enter to exit

using namespace std;

class Box //creates class
{
public: // do I even have to say it?
double hi; // creates a duobble variable, name variable hi
void setsup(int x)
{
sup = x;
}
int getsup()
{
return sup;
}
private: //really, it's self explanatory
int sup;

}

int main() //int main is need for every porgram, put as litlle as possible in there
{
Box Box1; //declares an object, Box1

Box1.hi = 4; //to name a variable in another class put object.classvar
Box1.setsup(5);

cout << Box1.hi << "\n"; // prints var or character if "" and \n makes new line
cout << Box1.getsup() << "\n";
//ending of program starts here
cout << "PRESS ENTER TO EXIT";
cin.ignore( numeric_limits<streamsize>::max(), '\n' ); //when press enter exits
return 0;
}

Use code tags please

Sorry

#include <iostream>
#include <limits> //include for press enter to exit

using namespace std; 

class Box //creates class
{
public: // do I even have to say it?
double hi; // creates a duobble variable, name variable hi
void setsup(int x)
{
sup = x;
}
int getsup()
{
return sup; 
} 
private: //really, it's self explanatory
int sup; 

}

int main() //int main is need for every porgram, put as litlle as possible in there
{
Box Box1; //declares an object, Box1 

Box1.hi = 4; //to name a variable in another class put object.classvar 
Box1.setsup(5);

cout << Box1.hi << "\n"; // prints var or character if "" and \n makes new line 
cout << Box1.getsup() << "\n";
//ending of program starts here
cout << "PRESS ENTER TO EXIT";
cin.ignore( numeric_limits<streamsize>::max(), '\n' ); //when press enter exits
return 0;
}

class Box 
{
    public: 
        double hi; 
	void setsup(int x){
            sup = x;
	}
        int getsup(){
            return sup; 
        } 
    private: 
        int sup; 

};

Semicollon at the end.

Also you probably want to define sup before using it in functions. So the private section should be at the top before the public section.

Why?

Matter of preference. I like to have members before methods, but that doesn't mean it [i]should[/i] be this way.

Fair enough. I just think it looks more readable if you define things before you use them in general. But, yes I suppose that is just my preference.
