July 03, 2004 I can't compile C programs w/input! | ||||

Sorry to bother you, but whenever i try to compile a program with
gets("%f", mph); or printf("%f", &kmph); in it, where im using gets()
for number inputand printf for number output, the compiler gives me the error:
1 actual arguments expected for printf, had 2
so, it seems to think that me setting the function up for printing numbers is actually using 2 arguments, when it's not. If you have advice on how i can fix or prevent this from happening, please reply.

Posted in reply to Pifs | Compiler may think of "printf" as taking 1 parameter only if you haven't
included stdio.h and compiler autoprototyped this functions from first call,
i.e:
printf ( "..." ); // not knowing anything about printf,
compiler may think that it accepts only one param
printf ( "%d", 2 ); // certainly compiler will give error here.
Make sure you #include <stdio.h> before you use printf or scanf
Also, "gets" is not for formatted input, use scanf instead. But as for my
feeling, I don't like scanf and never had luck to make it work.
