Chapter 5 Exercise 8

[Alistair]

Here is my solution for chapter 8, adapted from Program 5.8

Code: (Objective-C)

#import <Foundation/Foundation.h>

int main (int argc, const char * argv[])
{

    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
    int number, right_digit, sum;
    //right_digit = 0;
    sum = right_digit;
    
    NSLog (@"Enter your number.");
    scanf ("%i", &number);
    
    while (number != 0)
    {
        right_digit = number % 10;
        number /= 10;
        sum += right_digit;
    }

    NSLog (@"The sum of the digits is %i", sum);
    [pool drain];
    return 0;
}
