May be you should explain what is supposed to do your program !
An example input and out put wouldn't harm either.

Start by indenting your code properly - I've done that for you - so that it's actually readable.
Then sort out your variable names: one character variable may be easy to type, but they do not make c0ode readable as I have no idea what any of them are supposed to do. Calling "s" "source" or similar make take an extra character in modern IDEs but it makes the code self documenting and a lot clearer.

At the moment, I have no idea what your code is supposed to be doing, or what it actually does!

Looks to me like your code is working. Don't forget that the line you type in will show on the console before it is echoed by the program. Hence abc twice.

~~I have tested this and it appears that gets does not return anything if no input is typed.~~

ieven if i am giving ' '(space) as a character it is not reading it.
space must be printed as they r characters .....thats not a blank string

The issue is caused by scanf continuing to consume the input until a non-blank character is read. Just another reason why I never use scanf.

Just add the following line right after the puts( s ) line:

s[0] = 0;
