Write a program that prints the numbers from 1 to 100. But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”. For numbers which are multiples of both three and five print “FizzBuzz”.

FizzBuzz.m

#import <Foundation/Foundation.h>
 
@interface FizzBuzz : NSObject{
}
- (void)output;
@end
 
@implementation FizzBuzz
 
- (void)output{
	int i;
 
	for(i=1; i<=100; i++){
		if(i % 3 == 0 && i % 5 == 0){
			printf("FizzBuzz\n");
		}else if(i % 3 == 0){
			printf("Fizz\n");
		}else if(i % 5 == 0){
			printf("Buzz\n");
		}else{
			printf("%d\n",i);
		}
	}
}
 
@end
 
int main(int argc, const char *argv[]){
	FizzBuzz *fb = [[FizzBuzz alloc] init];
	[fb output];
	[fb release];
 
	return 0;
}
