error, idk how to fix...

[Aenoc]

here is my code,,.... it has 2 functions, 1 to raise a float number. say 3.4 to 4, and 1 to lower a float say 3.4 again, to 3....
when i compile the program it reads two errors.
1) line 28: warning: old-style declaration or incorrect type for: Uceil
2) line 36: warning: old-style declaration or incorrect type for: Ufloor
can anyone help???. its just practise for a midterm so no marks for it but i dont get why its doing it.. lol so may cause things on midterm...

code:

#include <stdio.h> /* function proto.s */ int Uceil  (float); int Ufloor (float); void main(void) { float num1, num2, num3, num4; int   V; printf ("Please type in the values of the 4 numbers.\n"); scanf ("%f %f %f %f", &num1, &num2, &num3, &num4); V = (Uceil(num1) + Ufloor(num2) - Uceil(num3)) * Ufloor(num4); printf ("The expression is V = (Uceil(%f) + Ufloor(%f) - Uceil(%f)) * Ufloor(%f).\n", num1, num2, num3, num4); printf ("The resulting value is: %d.\n", V); } /* function definitions */ Uceil (float num_up) { int tempV; tempV = (int) num_up++; return (tempV); } Ufloor (float num_dwn) { int tempV; tempV = (int) num_dwn; return (tempV); }

You have

c:

void main(void)

and

c:

Uceil (float num_up)

.

Both are bad.

The first because main() should be declared to return int in standard C.
The second because you are missing the return type--that is, you are using "implicit int".

There are more issues really, but I think you could figure them out.

It's not your fault that you missed the fixes.

C is a very permissive language. You can make mistakes and it'll still work... but just in some different way than you expected. Experience gives you the ability to deal with this effectively.
