This is where i get stuck. Any suggestions on how to get the size and compare it with the old one, other than ofcourse creating a for loop! LOL!

//'s' is the variable for the size.
int Bank::grow(int s = 10){
 
    int sizeOld = size; //used to save the size for future comparison
    if(savings != NULL){
        //create a new account object array
        Account *newSavingsArray = new Account[arraySize + s]
 
        //copy all data from old array to new
        for ( int i = 0; i < arraySize; i++ ){
              newSavingsArray[i] = savings[i];
            }
 
        delete savings;
        arraySize = arraySize + s;
        savings = newSavingsArray;
        } 
 
        else if (savings == NULL){
            //recreate the savings object with size 's'
            Account *savings = new Account[s]
            arraySize = s;
        }
 
 
	return arraySize;
