Thanks everyone, I will give it a shot when I get home.  I just thought that 
it was odd that it ran from the prompt one day and not the next.  The book I 
am using was pretty vague on the compiler syntax.  I compiled it without the 
.o extension as well, I was about to go out and purchase code warrior, so 
hopefully you guys just saved me some $$$  : )

I am pretty new to C++, compiling, etc., I really want to learn this 
stuff...  I am trying to figure out how to validate input from a user to 
make it accept only positive numeric values.  I was using a while loop to 
check it, but when the user enters an alpha character, I get stuck in the 
loop of death, I am sure many of you have experienced this.  I asked my 
instructor how to do this, but he said that he wasn't sure.  would an if 
statement nested in a while loop solve my problem??

Sorry about these newbie questions, but it's my second week in the class.. :

First the .o extension is for compiled but not linked modules.  Your
command line should be something like 'g++ Assn2.cpp -oexp1', or more
commonly: 'g++ Assn2.cpp -oAssn2'.

You problem is probably the 'current directory' is not in your PATH.  Try
executing your program with './exp1.o'.
