certainly! "delivering safe c++" is a talk by bjarne stroustrup at cppcon 2023 that focuses on best practices for writing safe and robust c++ code. while i can't provide a direct transcript or details from the specific talk, i can summarize some key concepts related to safe c++ programming and provide code examples that align with those principles.

key concepts in safe c++

1. **type safety**:
use strong typing to ensure that variables are used only in appropriate contexts.
2. **resource management**:
use raii (resource acquisition is initialization) to manage resources like memory and file handles.
3. **error handling**:
use exceptions and other mechanisms to handle errors gracefully rather than relying on error codes.
4. **const correctness**:
use `const` to enforce immutability where applicable, helping to prevent unintended modifications.
5. **smart pointers**:
prefer smart pointers (`std::unique_ptr`, `std::shared_ptr`) for automatic memory management and to prevent leaks.
6. **use of standard library**:
utilize the c++ standard library as much as possible, as it is well-tested and safer than custom implementations.

code example

here's an example demonstrating some of these principles:



explanation of the code example

1. **raii**:
the `resource` class demonstrates raii, where the resource is acquired upon creation and released when the object goes out of scope.

2. **smart pointers**:
`std::unique_ptr` is used to manage the lifetime of `resource` objects automatically, preventing memory leaks.

3. **error handling**:
the `processresources` function checks for null pointers and throws an exception if one is encountered, promoting safe error handling.

4. **const correctness**:
the `dosomething` method is a `const` method, indicating that it does not modify the state of the `resource`.

5. **standard library**:
the use of `std::vector` and `std::unique_ptr` from the c++ standard library ensures that ...
