[Dev-C++] I am stock!

[<Olu...@ao...>]

I am new to C++.  I am using Dev C++ on window platform.

I wrote my first c++ program called Hello World.  When i compiled it and run 
the program, there was no error.

The problem is that the result of the program just flashes and disappeared.  
I cannot read the outcome of the program which was meant to be HELLO WORLD.

How can i make the result of my program say a little bit longer on the screen 
before it disappeared? 

I am reading a book called Sams Teach yourself c++ in 24.  it never state how 
to overcome this type op problem.

Yours
