How to print out result on same line

[antony]

here is code and console view.
Question: if i want to put print out on one line instead of two how do i do that?
so like this "the 1st fraction is 1/3"
instead of
"the 1st fraction is
1/3"

heres code

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

//method of class
-(void) print;
-(void) setNumerator:(int) n;
-(void) setDenominator:(int) d;
@end


@implementation Fraction
-(void) print
{
   NSLog(@"%i/%i", numerator,denominator);
   
}

-(void) setNumerator:(int) n
{
   numerator = n;
   
}
-(void) setDenominator:(int) d
{
   denominator = d;
}



@end



#import <Foundation/Foundation.h>

int main (int argc, const char * argv[]) {
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
   //Fraction *myFraction;
   //myFraction = [Fraction new];
   
   
   Fraction *myFrac1 = [[ Fraction alloc] init];
   Fraction *myFrac2 =[[ Fraction alloc] init];
   
   
   // set fraction to 1/3
   
   [myFrac1 setNumerator: 1];
   [myFrac1 setDenominator: 3];
   
   [myFrac2 setNumerator: 4];
   [myFrac2 setDenominator: 8];
   
   // display fraction
   
   
    NSLog(@"the 1st fraction is:");
   [myFrac1 print];
   [myFrac1 release];
   NSLog(@"the 2nd fraction is:");
   [myFrac2 print];
   [myFrac2 release];
    [pool drain];
    return 0;
}

Here's console

Well, there are two ways:

1. Without using the print method. But to do this, you would have to add numerator and denominator methods to the fraction class.

Code: (Objective-C)

NSLog(@"the 1st fraction is: %i/%i", [myFrac1 numerator], [myFrac1 denominator );

2. Using printf instead of NSLog. The printf is a C function, that is basicly the same as NSLog, but it doesn't produce a line break at the end. If you do this you would have to modify the program like this:

Code: (Objective-C)

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

//method of class
-(void) print;
-(void) setNumerator:(int) n;
-(void) setDenominator:(int) d;
@end


@implementation Fraction
-(void) print
{
    printf("%d/%d \n", numerator,denominator);
    
}

-(void) setNumerator:(int) n
{
    numerator = n;
    
}
-(void) setDenominator:(int) d
{
    denominator = d;
}



@end



#import <Foundation/Foundation.h>

int main (int argc, const char * argv[]) {
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
    //Fraction *myFraction;
    //myFraction = [Fraction new];
    
    
    Fraction *myFrac1 = [[ Fraction alloc] init];
    Fraction *myFrac2 =[[ Fraction alloc] init];
    
    
    // set fraction to 1/3
    
    [myFrac1 setNumerator: 1];
    [myFrac1 setDenominator: 3];
    
    [myFrac2 setNumerator: 4];
    [myFrac2 setDenominator: 8];
    
    // display fraction
    
    
    printf("the 1st fraction is:");
    [myFrac1 print];
    [myFrac1 release];
    printf("the 2nd fraction is:");
    [myFrac2 print];
    [myFrac2 release];
    [pool drain];
    return 0;
}

Notice that there isn't a @ sign before the string anymore? That's because we're not dealing with Obj-C, but with C strings now.
