Pointer types, pointer arithmetic, void pointers

In this lesson, we will discuss why pointers are strongly typed, how they are de-referenced in memory, pointer typecasting and void pointers. We will look though these concepts through code examples.

your 10 minutes of video is more valuable than 6 hours of my teacher lectures:))) Thumbs up

Hi bmgag19,
You will have to acknowledge that people from different geographies would pronounce things differently. Even in a machine, Natural language processing does not happen through rules, it happens through statistical learning by training the machine on different accents. Larger and diverse the corpus, better is the natural language processing engine. In fact, standards and not strictly enforced in pronunciation. The most we can promise is being close to it. :)

one of the best teacher on internet. Thank you so much! can i buy you a coffee?

[parthvatsal]

I studied computer science in 2007 and I hated it because I never understood it. I wish your tutorials were there when I was a student. Maybe I would still have been in this domain.

The most amazing lectures I have ever seen 
The pointers were a myth for me since I was a student from 10 years ago

[kushagrasahu]

Clearly the best available lectures on YouTube for pointers. Hand down🙌🙌

[shivamverma]

Absolute masterclass displayed in these lectures. Made everyone's life

[hitikagahalot]

No one is better than you sir, you are made for this. We want you back sir.

[LousyPainter]

Your awesome! What else can I say? You are a great teacher! Great teachers are a rare breed.
Thank your Mother for giving birth to you! She deserves it.

In c++, We have to typecast it back to integer otherwise it gives some weird output.

int a=1025;
int *p;
p=&a;
cout<<"Size of Integer is "<<sizeof(int)<<endl;
cout<<"Address is "<<p<<"and Value is "<<*p<<endl;
char *p0; //Pointer to a char
p0=(char*)p; // Referencing the address
cout<<"Size of char is "<<sizeof(char)<<endl;
cout<<"Address is "<<(int*)p0<<" Value is "<<(int)*p0<<endl;
//Here, we'll have to type cast it back to integers.

I'm here, I'm sophomore .Thank you so much for creating lectures like this. I heard stories of Animesh and Harsha .The value that you create remains forever.Thank you !!!!

[leoonair]

The way you explain things are great. Like your voice, pace and using examples to give in-depth knowledge. Keep it going. Serving millions. Thank You.

[fangqingyu]

Most in-depth videos on pointers I've ever watched! Thank you for clearing the mist for me :)

[Slackero]

Finally. I think i understand pointers

[omarfarouk]

your English accent is clear and good, sir. Thank you for offering easy explanations

[ly]

You are a gift from the CS heavens! Thank You, your playlist saved my future!!

[Phantom]

I don't know how to thank you for the great explanation. You dive very deep to explain the concept clearly. Thanks a lot.

[FernandoBasso]

sizeof is an operator, not a function. Great videos. I'm learning a lot from them. Thanks a lot and keep up the amazing work.

[Brianmongo]

Finally.. hands down the best explanation

[trilecao]

This is the most fundamental lesson of pointer to be learned in C.
