Title: How to make a list with a dynamic length?
Post by: bobojoeho on March 15, 2024, 12:11:23 am

So I want to make a list that I can change the length of during my program.

Making an array requires me to set its length whenever I create the array, and that length is permanent.

Any ways to store a list of numbers, such that I can increase the length of the list or decrease it whenever I want?

std::vector is the class you want. It's a dynamic resizable array as part of the C++ standard.
