Code: (Objective-C)

#import <Foundation/Foundation.h>

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

        
        int sum = 1 ;
        
        NSLog (@"Table Of Factorial");
        NSLog (@" n    Sum from 1 to n");
        NSLog (@"--   ---------------");
        
                for (int i=1; i<=10; i++) {
                    sum*=i;
                    NSLog(@"%i %9i",i,sum);
                }
        
        }
    
}

Using nested for loop. microapple implementation is simpler less code.

Code: (Objective-C)

/*
 Programming in Objective-C, 4th edition
 Chapter 5 Exercise 3
 */

# import <Foundation/Foundation.h>

int main (int argc, char * argv[] )
{
	@autoreleasepool {
                   
		NSLog (@"n \t\t factorial");
		NSLog (@"--------------------------");
        		
		for (int i = 1; i <= 10; i++)
		{
			int factorial = 1;
			for (int j = i; j >= 1; j--)
            {
                factorial *= j;
            }
            NSLog (@"%i \t\t %i", i, factorial);
        }
	}
	return 0;
}

Output:
 n        factorial
 -------------------------------
 1        1
 2        2
 3        6
 4        24
 5        120
 6        720
 7        5040
 8        40320
 9        362880
10        3628800
