Problem getting my C program to run

I am having problems getting my C program to run it compiles OK but when I try to run it from a terminal I get an error command not found here is some output

linux-dhj2:/usr/lib/cprogs # cat helloworld.c
#include <stdio.h>
printf("hello world\n");

linux-dhj2:/usr/lib/cprogs # gcc -o helloworld helloworld.c
linux-dhj2:/usr/lib/cprogs # chmod 744 helloworld
linux-dhj2:/usr/lib/cprogs # helloworld
If 'helloworld' is not a typo you can use command-not-found to lookup the package that contains it, like this:
cnf helloworld
linux-dhj2:/usr/lib/cprogs #

I know C programming fairly well having worked on a comercial mfc C++ project (mfc sucks)

what am I doing wrong

In Linux, your current directory is normally not in your path. Many people believe there are important safety benefits from not having the current directory in the path.

So you need to type
in order to run an executable named helloworld in your current directory.

Try this one!
most likely your current working directory is not on your search path (for security reasons)...
