Thread: "Pointer" plus "Number"

Hi all,
let's say we have an array of char (thus array of "bytes"):

Code:

char pool[1000];

and let's say the 1st element of array is stored at address "00000000", the 2nd one at "00000001", the 3rd one at "00000002", ... , and the last one at "00000999":

Code:

printf("%d\n", &pool[0]);   // == 00000000
printf("%d\n", &pool[1]);   // == 00000001
printf("%d\n", &pool[2]);   // == 00000002

                                        .
                                        .
                                        .

printf("%d\n", &pool[999]);   // == 00000999

And now the problem begins.
Let's say we have "a pointer to int" which we will give the address of the 1st element in array:

Code:

int* pInt = &pool[0];   // It takes "4" first elements in array (sizeof(int) == 4)

And now if we would like to "add some number to that pointer", let's say:

Code:

pInt = pInt + 1;   // "pInt" now points to address "0000003" and no to "00000001"

But "I want to" do that addition so that pointer will point to the address "00000001"!
Is there any way to do it?


Thanks.
