How does memory management work for 2D vectors in C++11?

How does memory management work for 2D vectors in C++11?

In C++11, 2D vectors can be managed using std::vector<std::vector<T>>. Each inner vector can dynamically allocate memory.

What are the advantages of using std::vector over arrays?

std::vector provides dynamic sizing, automatic memory management, and built-in functions for easier manipulation compared to arrays.

Can you explain how to initialize a 2D vector?

You can initialize a 2D vector like this: std::vector<std::vector<int>> vec(rows, std::vector<int>(cols));.

What happens if I exceed the bounds of a vector?

Exceeding the bounds of a vector results in undefined behavior. It's important to check bounds before accessing elements.
