Question about void pointers.

[robgeek]

Hello guys.
I would like to know what's the difference between this to statements.

void function_test(void *l)
{
	//Both works fine, so, what's the difference between them considering good programming practice?
	int *num = l;//This one.
	int *num = (int*)l;//And this one.
	printf("The number is: %d \n",*num);
}

Thank you!

In C there is no difference. In C++ the first one doesn't compile because conversion from void* to another pointer type is not implicit.
