Chapter 7 exercise 2

[sonar]

O.K. i just looked at other answers before posting mine...

Of course I had to go another way of everybody else...

Code: (Objective-C)

-(void) print
{
	BOOL needsReduce;
	int preserveNum = numerator;
	int preserveDenum = denominator;
	int u = numerator; 
	int v = denominator; 
	int temp;
	while (v != 0) 
	{ 
		temp = u % v; 
		u = v; 
		v = temp;
	}
	numerator /= u; 
	denominator /= u;
	
	switch (u) {
		case 1:
			needsReduce = NO;
			NSLog(@"This needs NOT a reduce");
			NSLog(@"The result is %i/%i", numerator,denominator);
			break;
			
		default:
			needsReduce = YES;
			NSLog(@"The result is %i/%i", preserveNum,preserveDenum);
			NSLog(@"This fraction needs a reduce...");
			NSLog(@"The reduced result is %i/%i", numerator,denominator);
			break;
				}

I don't know if I've done the assignment correctly now... code seems to work!
