OK! I found out how to do this if anyone is interested. I just started programming in Objective-C and it is a bit of a mystery still and I probably jumped way ahead of myself with the comma thing but this seems to work now. Don't know for sure if every thing is proper. Any comments would be appreciated. Anyway here is the code:
CODE
#import <Foundation/NSString.h>
#import <Foundation/NSAutoreleasePool.h>
#import <Foundation/NSNumberFormatter.h>
#import <stdio.h>
int main(int argc, char *argv[])
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
[numberFormatter setFormatterBehavior:NSNumberFormatterBehavior10_4];
[numberFormatter setFormat: @"#,###"];
unsigned long long bigNum;
NSString *myString;
printf ("\n\tEnter a number: ");
scanf("%llu", &bigNum);
NSNumber *myNumber = [NSNumber numberWithUnsignedLongLong: bigNum];
myString = [numberFormatter stringFromNumber: myNumber];
printf ("\tMy number is %s.\n", [myString cString]);
[pool release];
return 0;
}
