Thanks to all! :) I understood!

i have this code and it works fine.

int fatt(int n)
{
int fattoriale = 1;

if(n==0)
    return fattoriale;
else
    return fattoriale=n\*fatt(n-1);

}

void main(void)
{
printf("%d\n",fatt(10));

fflush(stdin);
getchar();

}

my question is why it works fine also here ?

int fatt(int n)
{
int fattoriale = 1;

if(n==0)
    return fattoriale;
else
    fattoriale=n\*fatt(n-1);

}

void main(void)
{
printf("%d\n",fatt(10));

fflush(stdin);
getchar();

}

in this, there aren't the return in the else.... i am using VS2010 and compile in .c . thanks ps: sorry for my english
