Clear little database

Hi.
I was wondering if there is another way or better way to clear my database, I had this but I would like another way, to learn from.

PHP Code:

---

for ( int i = 0; i < 1024; i++ )
{

    string Database [ i ] = '\0';
} 


---

Why I am making such big deal is because I am still learning and I saw something like Array [ 0 ] = { 0 }; or something simular, what does that do? Could that be usefull?
Thanks, Yuri.

if Database is an array of POD (plain-old-data) types, such as char* then you can use memset

Code:

---

memset(Database,0,1024);

---

Sorry, I edited my thread, it's a C++ string.

Code:

---

Database.clear();

---

you can use generic template functions like these that work on any datatype that can be (safely) constructed without arguments:

Code:

---

template <class T>
inline
void
init(T & value)
{
        value = T();
}

template <class I>
void
init(I begin, I end)
{
        while(begin != end)
        {
                init(*begin++);
        }
}

template <class I>
void
init(I begin, unsigned n)
{
        while(n)
        {
                init(*begin++);
                n--;
        }
}

---

you could even optimize it further for POD's using some sort of template specialization scheme.
