62 - INTRODUCTION TO POINTERS & POINTER ARITHMETIC - C PROGRAMMING

Pointer Variable is used to store the address of another variable.
- Indirection Operator / De-referencing Operator / Value Operator
& - Address Operator

[@sundeepsaradhi]

HI VIEWERS SMALL MISTAKE IS THERE WHILE EXPLAINING THE POINTER INCREMENT WHAT EVER THE DATATYPE IT IS THE POINTER WILL INCREMENT ONLY 2 BYTES. AT THE TIME 21:50 I HAVE EXPLAINED WRONG. PLEASE MAKE A CORRECTION AND SORRY FOR THE MISTAKE.

have you released any books for c programming?

Thank you sir for these wonderful classes. Explanation is so good. Your classes helped me a lot..

[@Swarna_222]

Thanks for such amazing lecture

[@anupshastri2659]

at 20:08 Sir, does that mean, once we create a varible followed by *, like *p; and p=&a; the compiler is aware now that what ever the value is stored in the p is not simply an interger, to return the actual diffrence between two numbers like 1002-1000=2, but it understands that these are memory address and gives out the technical output which is 1. Have i got it right?

[@abdarshan975]

Yes

[@charancharan4956]

sir ur teaching is very good,sir pls try to upload more problems on topic not only pointers also other,so it is helpful to gain more confidence on topics .....tq sir

[@manalni_yevadra_apedi5602]

Sir value of a and value at address of a is same.then why should we use pointers

[@yashsstuff4570]

Is pre decrement operation valid with pointer variable (address)?

[@sirikisrinivasarao7994]

Sir, In other circumstances, if the p1- - is done, p1 value is 1000, if the other variable has address as 999, then what happens? Compiler will throw a error or will the line not work?

[@kz8328]

Superrrrb sir and my request is to solve some important or difficulty examples on perticular concept ,tq sir

[@halabuurniyadsame686]

Thank you boss i realy understood this wonderful explanation

[@hampongp5269]

You deserve million likes Sir 👍

[@vamsikrishnasai1682]

Sir a=2 P=&a then p is pointer variable ? Why we are using*p instead of declaring int p;

[@Rishignaonline]

To differentiate value variables and pointer variables

[@rameshk3699]

Sir Subtracting two address You took p2-p1 My question is If they do not point to same data type

[@jonykhan4395]

good expainaion1 please make a video on pointers and array or pointers and objects! thanks

[@SaranyaSaranya-cc4fs]

Amazing one sir, thank u so much sir

[@vinnu1322]

Sir integer occupies 2 bytes of memory but you draw (1:24) integer variable occupying only one byte check correctly

[@sundeepsaradhi]

hi and you are correct i had written wrong by mistake i have given 1 byte instead of 2 bytes. thanks for correction.

[@anupshastri2659]

but sir if 1000+1 in terms of pointer is 1002 then 1002+4 should be 1008?

[@urmilakanakala3559]

Sir why python doesn't support pointers concept? Could you please answer for this question

[@sundeepsaradhi]

hi Raj i didn't understand what exactly do you want me to clarify.

[@sameermohammad6648]

if pointer p is the last address in a memory...i.e after this memory is going to be filled...then how can we use increment operator in this case......which is similar to addition of two addressess

when p1++ then for all pointer it will be like 102 104 106 108 and in this video u said that for float 102 106 110 how it is plz explain.

[@sundeepsaradhi]

Hi chandu thats very nice observation and thanks for correction you are absolutely correct the pointer increments only 2 bytes for any datatype. once again thank you very much for correction.

[@rajarathanam21]

when i read in books i am not so clearly understood, Now thanks for your videos I want to ask.. what is advantage of using pointer functions?

[@sundeepsaradhi]

hi raja thanks for watching my sessions. Pointers are used when we allocate the memory dynamically.

[@lamo440]

actually in normal prgms not using pointer concept. when we declare variables in program and assign some value so dynamically it will allocate some space to a and automatically a variable will have some address so what's d use of using pointer concept.
