Filling and generating in STL containers

Populating containers and generating data within them is akin to molding clay into a sculpture. The data structure is your foundation, and the techniques to fill and generate data give life to your programs. As we continue to unearth the vast capabilities of the STL, this segment is dedicated to the pivotal techniques of filling and generating in STL containers. Let’s roll up our sleeves and dive into the art and science of crafting data structures with precision!

Populating with static assignment

Imagine a scenario where you need a container filled with a specific value, be it zeroes, a particular character, or any other repeating pattern. The STL simplifies this with methods tailored for static assignments.

For instance, the std::vector offers an overload of its constructor that allows you to specify a size and a default value:

std::vector<int> v(5, 2112);

Such a method ensures uniformity of data, which is essential...
