Answer 1

you should keep track of how many all the time so you know where to add the next element, but in some cases you cant, so you need to set up a loop to count the number of elements. you dont say what language, but heres some pseudocode:

count = 0
while myarray[count] is not equal to NULL
increment count
count now has the number of elements in the array

Answer 2

From the nature of your problem I assume that u are using a dynamic array.

These steps should work, though I have not tested them.

len(str())

See, if this works. Or, the best way will be to Set a counter which will increment every time you add a new element to the array. At any time, the value of the counter will indicate the no. of elements in your Array.

Answer 3
