void a_function( int a )
{
	printf( "%i\n", a );	
}

void another_function( void (*func)(int) )
{
	func( 1 );
}

int main( void )
{
	void (*func_to_call)(int);

	func_to_call = a_function;

	another_function( func_to_call );
}


so, a function with no args:
void (*func)();

a functions that takes an int and a char*
void (*func)(int,char *);

I think you can carry on from here. :)
