Looping problems (mine)

[anmldr]

Please debug this for me.  I get 201 as the answer.

Code: (Objective-C)

	int n, triangularNumber;
	
	triangularNumber = 0;
	
	for (n=1; n<=200;++n);
	triangularNumber +=n;
	
	NSLog(@"The 200th triangular number is %i", triangularNumber);

Thanks,
Linda

Linda,

Get rid of that ; at the end of the first line of the for.  That ends the loop right there!

Cheers,

Thanks.  I was reviewing some of the starting webcasts again.

It is often a colon or a semi-colon that is the problem.
