Puzzle for friends (and everyone :-) )

Hi all,

Well, this is a simple for loop (of course, which doesn't do anything specific!). Let's see if we can make it different.

int i, n = 20 ;
for ( i = 0 ; i < n; i -- )
  printf ( "-" ) ;

The problem is to make this for loop print the "-" exactly 20 times by either replacing, or adding or removing only a single character from the code. There are three solutions to the above problem.

By the way, Kocil, Akshay, haven't seen you guys around since a long while (matter of factly, I haven't been around much myself in the last few days. Am posting more on the Java forum now.) This is just an attempt to say Hi to all of you after a long time....

Anyways, everyone's welcome to answer. Let's see who gets all three correct solutions first!

Hi mayankeagle,

Here is the answer

1] Replace i by n in for loop.
   for ( i=0;i<n; n--)
2] Replace i by -i in the for loop.
   for (i=0; -i<n ;i--)
3] Replace < by + in the for loop.
   for ( i=0; i+ n; i-- )

Nopes,  sorry. I guess you're some other Amit Gupta :-) I'm Mayank Shridhar.
That's a great coincidence.

Actually I did had a look at your profile (after answering) when I looked at your login-name and had a slight blink in mind about one of my college friend - mayank
But then thought it to be a remote possibility

Anyways, that also shows the abundance of people named Amit Gupta.....:(

I would love to have friends like u......   :)

Nopes, in that case, control won't go into the for loop at all as ( i < n ) is not satisfied initially.
for (i=0; ~i<n ;i--)
