char someArray[256];  // allocate an array of characters
char* pItemOfArray = someArray; // create a pointer that 'points' to the first element of the array

// do something to fill the array with data

while (*pItemOfArray != '\0') // repeat some code while the array item contains some non-zero value
{
    // do something with the item that the pointer points to, for example
    *pItemArray = *pItemArray + 1; // add 1 to the item
    pItemArray++;  // update the pointer to point to the next item
} // and continue the loop
