//	demo1.c
//
//	This very simple application program merely adds two
//	specified integers and prints out the resulting sum.
//	It is written using the C programming language, just
//	to illustrate the distinction between a "high-level"
//	language and a "low-level" language (like assembly).
//	This demo should be compared with 'demo2.s' which is    
//	a "low-level" version of the very same computation.
//
//	compile using:	$ gcc demo1.c -o demo1
