hello world question

[Kalyan Vaidyanathan]

Hi,
  Have a very basic question in C.
* I have installed RH 7.2.
* I created a file called hello.c which looks like this:
    #include<stdio.h>
    main() { printf("Hello World\n"); }
* To compile and run it, on a terminal window, I typed the following:
    >gcc hello.c
* I get no errors and a.out is created
* I try to run a.out and I get the following error
   >a.out
   bash: a.out: command not found

I am not sure if I have some env setting that is wrong.  Can somebody point 
me to the right direction?
thx and regards,
-k
