Help in pointers to array - C++

I've created an array and a pointer to it..i read in cprogramming.com that when you create a pointer to an array you don't have to use the (&) sign and it gives the memory address of the first element to the pointer...
what if i want memory address of other elements?

please help..

You use either (e.g. to get the address of element with index 2):

Code:

---

&a[2];
a + 2;

---

The above are both equivalent. As an aside, you should now see that you could have used "&a[0]" for the first element, and that this is equivalent to "a + 0", which can be used as just "a".

Thanks a lot....
it helped me very much and i made a successfully running program..
here it is:

Code:

---

#include <iostream>
using namespace std;


int main(){


    int a[5];
    a[0] = 1;
    a[1] = 5;
    a[2] = 0;
    a[3] = 9;
    a[4] = 99;
    int *b = a;


    for(int a = 0; a < 5; a++){


        cout << "Array index " << a << "\tmemory address " << &b[a] << "\tvalue " << b[a] << "\n";


    }
    cin.get();


}

Good. Note that instead of:

Code:

---

int a[5];
a[0] = 1;
a[1] = 5;
a[2] = 0;
a[3] = 9;
a[4] = 99;

---

you could have written:

Code:

---

int a[5] = {1, 5, 0, 9, 99};

Also, as a matter of style, the double blank lines in your main function's body are unnecessary: a single blank line or in this case no blank line would do.
