Hello! i got this code. However i'm really not familiar with memcpy function. Can anybody can show me the other way to write that code without using memory function?

```
void rightRotate (int k, int n)
{
char temp [2*MAX], *saveptr;
saveptr = num+k; //
cout << "k" << k << "\n";
memcpy (temp , saveptr, n);
memcpy (temp + n , saveptr, n); //
memcpy (saveptr, temp+n - 1, n); //
}
```

i'm familiar with this code:

```
void rightRotate(int *y, int n)
{
int temp ;
for (int i = 1; i<= n, i++)
{
temp = y[i];
y[i] = y[n-i+1];
y[n-i+1] = temp;
}
}
```

is it similar?
