    Exclamation HELP! im looking for different ways .

    Im looking for ways to use arrays using pointers.
    an ex is:
    #include<iostream.h>
    #include<conio.h>
    void main ()
    {
    int sales[7]= {1,2,3,4,5,6,7}
    int*p=&sales[0];
    int x;
    //-----------------------------
    for(x=0; x<7; ++x)
    cout<<"$"<<sales[x]<<" ";
    cout<<endl;
    //-----------------------------
    for(x=0; x<7; ++x)
    cout<<"$"<<p[x]<<" ";
    cout<<endl;
    //-----------------------------
    for(x=0; x<7; ++x)
    cout<<"$"<<*(sales+x<<" ";
    cout<<endl;
    //-----------------------------
    for(x=0; x<7; ++x)
    cout<<"$"<<*(p+x)<< " ";
    cout<<endl;
    getch();
    }

    \\ all of the above give the same result
    \\$1 $2 $3 $4 $5 $6 $7

    any more ways???????

    congrats, you just ruined your pointer.

    Code:
    int num[5] = {2, 6, 9, 2, 2};
    int *ptr = num[1];
    cout<<ptr;
    output :
    Code:
    6

    using & means its appointed to a reference so:

    &num = numb;

    would not make &num = numb, it would just replace it when it comes up in the program so:

    cout<<&num;

    would display numb and not &num

    cout<<num;

    would display the address of the variable numb
    ex:
    output : Ax00A4b00

    (maybe its not a real address i dunno but it looks kinda like that)

    dont try modifying addresses cause u could mess up your computer -_-'
