Error Message

I'm getting the following error message:
"Warning [2058] call of function without prototype" when I try to do the following code:
printf("Seconds: %d \n",seconds);
Problems?

you need to put

Code:

#include "printf_lib.h"

at the beginning of every file that you want to use printf in, or else the compiler will yell at you like that.

Re: Error Message

This doesnt have to do with the function being prototyped, but when it works, you will need to change your statement to:

Otherwise you will not get the value that you want.

Re: Error Message

Type casting is not the problem here. Even if the type cast is wroung the program will still compile, you'll just get undesired results thats all. Kinda like this

Code:

 Printf("4 + 4 = %d");

 //this could return anything like "4 + 4 = 4098

 //now how did that happen?

Re: Error Message

The syntax error has already been pointed out. Damian was just pointing out a much harder to find logic error.
