Declaration of Instance Variables wrong?

Question

My instance variable secondNumber is not declaring itself. Why not? (I am new to programming, so please bear with me.) In Xcode the error says, "Parse Issue: Expected ';' at the end of declaration list.

//  main.m
//  Subtraction
//
//  Copyright 2012 __MyCompanyName__. All rights reserved.
//

#import <Foundation/Foundation.h>

@interface NumberSub: NSObject

{
int firstNumber
int secondNumber
int result 
}
-(void) print;
-(void) setFirstNumber: (int) f;
-(void) setSecondNumber: (int) s;
-(void) resetAll;
-(void) printResult;
@end

@implementation NumberSub

-(void) setFirstNumber: (int) f;
{
firstNumber = f;
}

-(void) setSecondNumber: (int) s
{ 
secondNumber = s;
}

-(void) print
{
NSLog(@"%i - %i = ", firstNumber, secondNumber);

}

-(void) printResult
{
NSLog(@"%i", firstNumber - secondNumber);
}

-(void) resetAll
{
firstNumber = 0;
secondNumber = 0;
}

@end

int main (int argc, char *argv[])
{
NumberSub *subtractNumber = [[NumberSub = alloc]init];



[subtractNumber setFirstNumber: 10];
[subtractNumber setSecondNumber: 5];

[subtractNumber print];
[subtractNumber printResult];

[subtractNumber release];   
return 0;
}

"Parse Issue: Expected ';' at the end of declaration list." is a pretty clear statement ;) — MJVDM

You forgot the ; at the end of each lines

@interface NumberSub: NSObject

{
    int firstNumber;
    int secondNumber;
    int result ;
}
