c++ a.out command not found

[kintrast]

Recently got Fedora 16 and from terminal window did ' yum install gcc-c++ '
Using vi wrote simple c++
Then compiled ' g++ Hello.cpp ' OK so far
Typed ' a.out ' and got
bash: a.out: command not found...

I am puzzled. Anybody got any ideas what I have done wrong?

Try "./a.out".

By default your search path does not include the current directory for security purposes. It is safer to not have trojan commands that may exist in your working directory (or /tmp if you ever go there) executed by accident.

Well blow me that works. Thanks for that. When I used to work with c++ a decade ago I used a.out pretty regularly. So this is different now.

Thanks

The different behaviour is probably due to the PATH variable. If PATH includes "." (=the current dir), then a.out works. If PATH does not include ".", a.out does not work, and you have to specify ./a.out to execute.

Yes I understand that now and thanks for your communication it is much appreciated.
