Trivial C question: iterating through chars

[Chris Richard Adams]

I'd like to view all the ASCII chars on my system.  I tried:

char ch = 'NUL';
int i;

for ( i = 0; i < 500; i++)
	printf("Char: %c/n", ch + i");

This fails.

1.) What is illegal here?

2.) Can I use chars in my for look also...something like:

for ( ch = 'NUL; i < 500; ch++, i++)

Thanks,
Chris
