bad type declaration

[ClaudioDaffra]

i have triedto run 42_function_pointer.c example
but gives me an error about function pointer :
bad type declaration <-- int (*f)(int) = &fred;

#include <stdio.h>

int fred(int p)	{
	printf("yo %d\n", p);
	return 42;
}

int (*f)(int) = &fred;

int main()
{
	printf("%d\n", (*f)(24));
	return 0;
}
