honestly the way u explain pointers is very fascinating and easy to remember keep it up brother 😁

finally programming tutorials thtat can be watched on smartphone

Finally an accent which is understandable ^^' I really tried to follow all the indian dudes but sometimes I just wasn't sure I understand it correctly. They all made good videos (I think) but it was so hard to understand them, because they all try to beat eminem in saying the most english words in one minute xD

Thank you for this great video! Really enjoyed your presentation. As a novice C programmer, here's one (brute-force way) to specify to what type to cast the void pointer inside the function: #include void printBytes(void*, int size); int main(int argc, char *argv[]) { int arr[] = { 16, 31, 32, 65 }; printBytes(arr, 4, sizeof(int)); } void printBytes(void *arr, int size, int typeSize) { for (int i = 0; i < size; i++) { switch (typeSize) { case 4: // Cast the void pointer to appropriate type then dereference it to get it's value. printf("%08x", ((int*)arr)[i]); break; default: printf("????"); break; } printf("|"); } } Outputs: 00000010|0000001f|00000020|00000041|

My brain is like splash-splash after this video

It's important to note that casting a pointer to a pointer of incompatible type is undefined behavior since it violates the C strict aliasing rule which is designed for code optimizations. You can however cast to and from void and char pointers and compatible pointer types. In particular 2:23 is erroneous (you can see that the compiler outputs a warning) but 8:04 technically isn't(the warning stays since the pointers are of different type but the code would always work fine and it isn't dangerous). GCC turns on this rule in -O2 and -O3 optimization levels with the -fstrict-aliasing flag.

void pointers are also used for assigning callback functions. That’s what I used void pointers for.

Finally I understand it! Thank You!

Excellent video.

Love your hacker style so interesting

Well done !

When you go to Walmart to buy some socks and end up with an ironing board, 2x HDMI cables, Fruity Pebbles, and foot lotion.

4:35 can cast it before dereferencing

Do you have a video where you discuss what hexadecimal is?

But what if we cast the arr to lets say int or long int type? Then we dont need to put 4*sizeof() but only 4, right? Will it work?

I love you

Stupid question: why print it in hexadecimal?

char* arr -> char *arr
