Chapter 5 Exercise 8

[WANGOOROO]

Here is my version of Chapter 5 Exercise 8.

I get the result I want, but using the method with % I am adding the digits of the supplied integer in reverse order.  Not sure it really matters as the end value is the same. 

--------------

Code: (Objective-C)

/*	Chapter 5 Exercise 8
	Write a program that calculates the sum of the digits of an integer
	
	For example: the sum of the digits of the number 2155 is:
	2 + 1 + 5 + 5 = 13
 
	The program should accept any arbitrary integer entered.   */


#import <Foundation/Foundation.h>

int main (int argc, const char * argv[]) 
{
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
	
	int number, right_digit, sum;
	
	sum = 0;
	
	NSLog(@"Enter your number.");
	scanf("%i", &number);
	
	while ( number != 0 )
	{
		right_digit = number % 10;
		sum += right_digit;
		NSLog(@"%i", right_digit);
		number /= 10;
	}
	
	NSLog(@"The sum of these digits is: %i", sum);
	
	[pool drain];
    return 0;
}

Your approach is fine.
