#import <Foundation/Foundation.h>

@interface Fraction: NSObject
{
int numerator;
int denominator;
}

-(void) print;
-(void) setNumerator: (int) n;
-(void) setDenominator: (int) d;
@end


@implementation Fraction
-(void) print
{
NSLog (@”%d/%d”,numerator,denominator);
}
-(void) setNumerator: (int) n
{
numerator = n;
}
-(void) setDenominator: (int) d
{
denominator = d;
}
@end



int main (void)
{

Fraction *frac1 = [[Fraction alloc] init];

Fraction *frac2 = [[Fraction alloc] init];

[frac1 setNumerator: 2];

[frac1 setDenominator: 3];

[frac2 setNumerator: 3];
[frac2 setDenominator: 7];

NSLog (@”First fraction is:”);

[frac1 print];

NSLog (@”Second fraction is:”);

[frac2 print];

[frac1 release];

[frac2 release];
}
