I am new linux user.

I can compile my c++ code in my user directoy (for example
/home/username) but when I try to excute the the excutable I have to
give the whole path( /home/username myexcutable) even I am in the
diretory /home/username, How can I fix this problem.

a couple of things to consider.

What is the path?  echo $PATH will show you the current path that the
shell looks through for exectables.

I believe RHL no longer puts the current directory in the path by
default.  

you either:
 add . to your path in ~/.bash_profile (don't forget the : separator) 

put it in a place that the shell will look like ~/bin 

or to save key strokes if neither of these options are what you want you
can simply type ./progname.  The ./ is the current working directory.

putting . in your path is considered by most to be a security issue
since you might inadvertantly run a program named the same as a common
command or a simple typo can cause a different program to run.
Definitely not a good idea for root's account. 

BTW ~/ is the current user's home dir in bash anyway not sure bout other
shells.
