C++ POINTERS (2020) - How to create/change arrays at runtime? (Dynamic arrays) PROGRAMMING TUTORIAL

Рет қаралды 149,099

Күн бұрын

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.

Thank you so much for your lecture. It's very good and it helps me alot. I have a question regarding to deallocate memory: What if we don't call delete[]myArray but just only call myArray = NULL; ? Can you explain what will happen?

Love your videos! Currently in my last year for my bachelors and have this crazy 7 hour long test at the end of the semester where 1/4 of it tests my c++ knowledge. If I get anything less than a 70 on the test I auto fail no matter what I have on anything else turned in during the semester. Reviewing c++ with your tutorials is seriously boosting my confidence! thank you..

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.

I have an excercise where I am given a dynamic array A of strings, I need to implement function foo(string &A, string s) to append the string s to the array A. So if I am not provided with the size of the array, how can I solve this? tysm for any suggestions.
