Memory of an Array

Question

How much memory an Array can take (like integer 4 bytes)?
is this varry through array data type??

Answer 1

Each element can be the size of whatever data type the array is. So each element would be 4 bits, if it is an int array. The size of the array determines how much total memory the array will/can use.

As for the maximum amount of memory you can use, that'd probably be until you get an out of memory error.

Answer 2

memory of an array is

no of total elements * size of integer

each element in an int array has 4 bytes.

ex
int ar[10][10];

has memory 10 * 10 * 4 = 400 bytes

Answer 3

You mean how many elements you can store in an array?
You can do it static: int array[5];
Or dynamic with allocating memory and extending it when you need to.
But the easier version is to solve it the static way.

Oh and for the size: it takes x times the size of the datatype you specify the array. so if you define the array "int array[5]" it would need 5 times the space of the datatype of int on your system.
