	/* example program illustrates difference between static and automatic variables */
	#include <stdio.h>
	void demo( void );               /* ANSI function prototypes */
		
	void demo( void )
	{
		auto int avar = 0;
		static int svar = 0;
		
		printf("auto = %d, static = %d\n", avar, svar);
		++avar;
		++svar;
	}
	

	main()
	{
		int i;
		
		while( i < 3 ) {
			demo();
			i++;
		}
	}
