a.out output not displayed

a.out output not displayed

[Raja Loganathan]

hi,

My gcc compiled programs are not showing the output.

I compiled a simple printf("\nHelloworld");

./a.out .. I'm not getting any output on the screen. However Shell 
commands, echo etc works properly.
I checked my program in other shells. It works properly.

Thank you,
Raja

You need a \n at the end of your printf.  Or set the zsh option:

   setopt no_prompt_cr

By default, zsh returns to lefthand side of the terminal to display the
prompt.

This problem is a zsh "rite of passage".
You also get it with
perl hello.pl

It doesn't (the prompt position is incorrect with other shells).

Which is bad. The best solution is to use a recent zsh version
(4.3.0-dev-5 or wait for 4.3.1).

Or look at a recent copy of the zsh FAQ, which explains how users of 
older versions can employ the fix that's built in to upcoming version.
