"Expected undefined-id" Error Message

FlyingShoes12 · 11-03-2009, 05:06 PM

Ok, I just switched from C to C++, so please bear with me...

I am writing a simple code to make sure I understand classes, and am getting the error message:

Code:

error: expected unqualified-id before âintâ

what am I doing wrong? Here's the full code:

Code:

#include <iostream>

using namespace std;

class firstclass
{
public:
    firstclass();
    int sum( int x, int y );
    ~firstclass();
};

firstclass::firstclass()
{
    int z = 0;
}

firstclass::int sum( int x, int y)
{
    z = x + y;
    return z;
}

firstclass::~firstclass()
{
}

int main()
{
    firstclass math;
    int a = 0;
    int b = 0;
    cout<<"Enter two numbers: First:  ";
    cin>> a ;  
    cout<<"\nSecond";
    cin>> b ;
    cout<<"The sum is"<<math.sum( a, b )<<"";
}

Writing a member function doesn't look like

Code:

firstclass::int sum( int x, int y)

but like

Code:

int firstclass::sum( int x, int y)

(I.e., the qualifier is on the name, not the return type.)
