I am just getting started with C and have been doing some basic programs and such when today, we I tried to make a program expermenting with the float data type, I would get a error in debug referring to the header.

c:\program files\microsoft visual studio\teststido\teststido.cpp(12) : f
cruiouse, and unable to solve the problem, I tried other programs that included "printf" and the header stdio.h and all of the programs returned the same error on debug. Even code as simple as:

#include <stdio.h>

main()
{
printf ("lala.\n");
return ();
}

returns that error, I could use any help, thanks ^ ^
