7 Segment Library for Arduino 1.0

Sorry for the confusion. Here are the latest files. I am still getting an error message though.

Soda Demo:

// Soda Demo

#include "Soda.h"

Soda soda;

void setup() {
  soda.pins(2, 3, 4, 5, 6, 7, 8, 9);
}

void loop() {
  for(int i=0; i<10; i++) {
    soda.write(i);
    delay(1000);
  }
}

Soda.h

#ifndef Soda_h
#define Soda_h

#include "Arduino.h"

class Soda
{
public:
    uint8_t pins(int a, int b, int c, int d, int e, int f, int g, int dp);
    void write(int number);
    
private:
    int _a, _b, _c, _d, _e, _f, _g, _dp, _number;
    const byte numeral[10];
    const int segmentPins[8];
}

#endif

Soda.cpp

#include "Soda.h"

uint8_t Soda::pins(int a, int b, int c, int d, int e, int f, int g, int dp) {

    _a=a;
    _b=b;
    _c=c;
    _d=d;
    _e=e;
    _f=f;
    _g=g;
    _dp=dp;
    
    segmentPins[0] = _dp;
    segmentPins[1] = _g;
    segmentPins[2] = _f;
    segmentPins[3] = _e;
    segmentPins[4] = _d;
    segmentPins[5] = _c;
    segmentPins[6] = _b;
    segmentPins[7] = _a;
    
    for(int i=0; i < 8; i++) {
        
        pinMode(segmentPins[i], OUTPUT);
    }
    
    
}

void Soda::write(int number) {
    boolean isBitSet;
    
    numeral[0] = B11111100;  // 0
    numeral[1] = B01100000;  // 1
    numeral[2] = B11011010;  // 2
    numeral[3] = B11110010;  // 3
    numeral[4] = B01100110;  // 4
    numeral[5] = B10110110;  // 5
    numeral[6] = B10111110;  // 6
    numeral[7] = B11100000;  // 7
    numeral[8] = B11111110;  // 8
    numeral[9] = B11100110;  // 9
    
    for(int segment=1; segment < 8; segment++) {
        if(number < 0 || number > 9) {
            isBitSet = 0;
        }else{
            isBitSet = bitRead(numeral[number], segment);
        }
        isBitSet = ! isBitSet;
        digitalWrite(segmentPins[segment], isBitSet);
    }
}

And here is the same error message that comes up with soda demo.

SodaDemo:2: error: new types may not be defined in a return type
SodaDemo.cpp:6: note: (perhaps a semicolon is missing after the definition of 'Soda')
SodaDemo:2: error: two or more data types in declaration of 'setup'
SodaDemo:4: error: structure 'soda' with uninitialized const members

Any Help?

Thanks,
