In this video we 'll discuss how to da Rays are related with pointers
how you can access the elements of a 2d array with the help of
pointer rather than using the array name. If you have discussed the
relationship between arrays and pointers I mean that 1d array and
pointers you can check out that video also in that I button. A of 0
contains these three integer values and this is the base address of
these arrays. P can contain address of an integer variable only so
this is invalid right so here can we write P is equal to CP contains
address of some another integer variable address off integer
readable so can I write here a the name of theory. If you want to
print in hexadecimal form you can write down percentage P. you
fine it will print in unsigned integer some integer value so you can
print if you print in printf I guess you can. write printf % is you and
you. can write what a simply the name of the area or it will give
what the address of the first element first element is what a of 0 0 is
what 100 only fine you can say that base address of this is 100.
1d array value doesn't mean does n't mean that it is returning either
six two or five because at a over zero at this address it will return at
this element. If you write this 1s trick a plus 1 then what should be
the value C this a name of the 2d array. A means same name of this
2d array it is going to points to the first element but you can say it's
going to return the address of first element. If you do s trick a of 1 it
means when you act this pointer value at this address when you is
this complete 1d array value is not single integer value. Esther
explains how to print a of 1 plus 2 plus two and you just write a
straight fine. Esther says the output of this thing should be the
output, just think about it see Esther it a here step by step here in to
solve this a a means it is going to return a snake of 2d array.
Esther: If you you are going to print this value then simply you can
write say this one this is same this is giving.
, A straight a astray K means value at this address value is what
value is this complete 1d array fine or you can say address of its
first element first element in 2d arrays this complete one dear so it is
going to return pointer to this one da find out. If you print history s
trick a then what will be the output of AD Esther that's tricky and
Esther gets trick P. Address of a means it is going to give you the
address of the first element of the array. If you print a and address
of a a a means name of an array C name of there is address of a
and a both will return 200 fine. If a plus one arithmetic plus one in
the pointer then it is pointing to the CUDA obviously the next
element. here 1 2 1 2 the next element it is going to switch this
complete array then it is. going to point this the next. element of or
you can say the next one the error that is 1 2 4 this is the difference
between this and this see I can now discuss everything in one video
so it 's up to you you can try different different different expressions
like this.

Memory is very crucial data source in our
system we do n't have unlimited memory in a
computer system fine so it is a responsibility of
a memory manager to manage this resource.
