New to g++ and linux - Class path problem?

[Todd Hoffman]

I am new to linux and g++.  I have just installed linux on one of my PCs
with a red hat distribution.

I am doing some C++ programming on this machine, and I can compile my source
just fine, and g++ creates an a.out file.

I am in the directory that contains the a.out file, and I type a.out.  I get
an error message that says command cannot be found.

Is this a path environment problem?  Is there a command I can use on the
command line to use the current path, or is there a settings file where I
can define my class paths?

Thanks in advance for the help!
