when I go to compile it I get this:
"fig619T.c", line 22.18: 1506-277 (S) Syntax error: possible missing ',' or ']'?
"fig619T.c", line 25.3: 1506-273 (E) Missing type in declaration of printf.
"fig619T.c", line 25.3: 1506-343 (S) Redeclaration of printf differs from previous declaration on line 263 of "/usr/include/stdio.h".
"fig619T.c", line 25.3: 1506-378 (I) Prototype for function printf cannot contain "..." when mixed with a nonprototype declaration.
and also, what line is line 25.3? where do I count from- the top?
thanks
