Dynamic arrays are arrays that are allocated at the run time, rather than at compile time. Because of that Dynamic array can change its size during run time.
In this video, I’m explaining the most important differences between arrays and linked lists, demonstrating how to allocate and deallocate memory using “new” and “delete” keywords, and how to create and use dynamic arrays.
We’ll be writing C++ code using Visual Studio 2019 Comunity.

is it the same as a vector?
int size;
cout<<"Enter size:";
cin>>size;
int array[size];
doing it like this does not give any errors to me. can someone explain.
This is enlightening thank you!
Really beauty coding
I am very sad!!
because she didn't reply me on Instagram,
please reply to me sis….
How about a dynamic array function? Can you give me one example.
The goddess of intelligence and beauty~

Dear saldina will you please tell me where these dynamic arrays are used ? Explain with example
Why am I able to run my code using a normal array of a size defined by the user? I'm coding in Visual Studio Code. My code looks like this:
int main()
{
int size;
cin >> size;
int myArray[size];
for (int i = 0; i < size; i++)
{
cout << "Array[" << i << "]: ";
cin >> myArray[i];
};
It runs just fine but I also know that you cant append or pop items to/from an array like in Python for instance. So why is my code right or wrong?
Please Video between LinkedList and Arrays .
Omg a good dynamic array deallocation explanation thank youuuuuu
Very interesting video, you're amazing Saldina 😉 Thank you very much for the time you spend making those videos 😉
how can I initialise the array with let’s say all 1s or any number ? Right now it’s all zeros right?
Peace Out sis! 🙂 🙂
hola 🙂
Great explanation! Thanks 🙂
int size;
cout<<"Enter size:";
cin>>size;
int array[size];
doing it like this does not give any errors to me. can someone explain.
Best explanation! Much appreciated.
Make the videos on linked list, btree, stack, Queue
In your first example when you allocate memory for the array. Was that necessary? I tried it without allocating memory with "new int" and the code worked anyway.
Thank you very much.
You told in the tutorial that the integer number of the array must be constant…after watching your video,I tried to do this & I expected that codeblocks will see me a error…..bt it didnt show me any error.I took input from the user & assaigned it to the array,& it runs without creating any problem. How this is possible?I put my code in the comment.Please kindly let me know about this if you see my comment🙂
Excellent. I have a question. Why don't we need the zise of array when we delete? How compiler know how many bytes it need to free? Thank you!
can you compare some of these concepts and syntax compatible with C? I know since C is not a OOP so one wouldn't expect to see classes there. But concepts like this would be in C as well.. Can you please talk about malloc(), calloc(), free() and realloc(). What is the difference, which one is better in what conditions. etc..
Why don't use nullptr instead of NULL? Thank you!
Aight. Finally something good on YouTube
Just subbed you today after watching 5 of your vids thanks for putting effort
