Array Lengths?
-
Hey Everyone, I've got a short array that starts with 1 element (obviously) and it grows if it needs more elements. Untimately the array needs to grow as much as possible to suit the program.... I don't know however, how to return the size of the array. e.g. ShortArray[0] = 1; ShortArray[1] = 5; Length of the array is 2... Mean there are two elements. How do you return the length? Thanks for your help in advance.... I appreciate all your input :-) Cheers, Michael

How did you declare the array?

This means you dynamically allocate the memory?

register short* PrimeNumber = 0; That's how I declared the array.... I would change it if I need to though. Yeah I want allocate it more memory during runtime i.e it grows. Cheers, Michael

Use a
std::vectorand be done with it.

The memory can be allocated like PrimeNumber = new short[2];// an array having length of 2 is created So 2 is length of array. Similarly you can put the number of element you want in the array in the place of 2.

Do you know any methods or functions that return how many elements that are in the array? Like before Array[0] = 1; Array[1] = 2; There are "Two" elements in this array. Do you know of anything like that? Cheers again, Michael

Sorry I dont get your question correctly. Suppose you are allocating a memeory with size 5. Then the length of the array is 5. And whats the confusion in that? you can get the size of memory that you dynamically allocated using new or malloc using the function
_msize(). Is that what you want?nave [OpenedFileFinder]

const unsigned int length = sizeof(ShortArray)/sizeof(ShortArray[0]);
That is, you divide the amount (in bytes) of your array by the size (in bytes) of one element.
