1.1 Arrays in Data Structure | Declaration, Initialization,
Memory representation
It is to be stored in memory now as you can see theory is stored in 20 bytes memory starting
from the 0th byte and ending at the 19th byte. So theory is stored in consecutive bytes in
memory. Now If I want to access any of these elements, I will use the indexing operator,
which is the square bracket []. So I can say here [0] that is the first element of this array. Now
if I want to access any other element. I will use the indexing operator again and this time I
will use the plus sign (+). So I can say here [1] that is the second element of this array and so
on until I reach the last element of this array, which is [19]. So this is how you can access any
of these elements of the array using the indexing operator [] and then using the plus sign (+)
see now Another way to initialize an array at runtime is by using a pointer variable. See now
suppose we have a pointer variable called p that points to an area in memory that contains
an array called [UNK] fine now at runtime. We can say p->elements[0] that is referencing the
first element of [UNK] See now Another way to initialize an array at runtime is by using a
const pointer variable. See now suppose we have a const pointer variable called p that
points to an area in memory that contains an array called [UNK] fine now at runtime. We can
say const p->elements[0] that is referencing the first element of [UNK]. See now Another way
to initialize an array at runtime is. a dynamic pointer variable see now suppose we have a
dynamic pointer variable called P that points to an area in memory that contains an array
called [UNK] fine. Now at runtime, we can say p->elements[0] that is referencing the first
element of [UNK], but what if we want to access more than one element from this array at
runtime. What would we do see now suppose we want to access both [1] and [2] from this
array at runtime. We can do this by using the two indexing operators [] and (+) Like this see
now another way to access more than one element from this array at runtime is by using a
compound assignment operator (=). Like this see now suppose we want to access both [1]
and [2] from this array, but we also want to assign them both to another variable called V
right so we. Do like this P = V[1] + V[2] see now one more way to access more than one
element from this array at runtime is THe data for this array is stored in 4 bytes starting at
offset 0. THe base address of this array is 100. THe address of the first element in this array
is 0. THe author suggests that in order to access an array's data, you need to know the
