Complete Modern C++ - Compiled Time Argument Deduction (CTAD)

The video tutorial explains template argument deduction in C++, focusing on its evolution from C++14 to C++17. It introduces Class Template Argument Deduction (CTAD), which allows the compiler to deduce template arguments for class templates, simplifying code by eliminating the need for make functions. The tutorial covers both compiler-generated and user-defined deduction guides, providing examples with pairs, mutexes, and custom types. It highlights the advantages of CTAD, such as code simplification and flexibility in handling different data types.

What is the significance of using CTAD with objects created on the heap?

In what scenarios might you prefer to write your own deduction guide instead of relying on the compiler's default behavior?

Describe how you can customize the deduction process using a deduction guide.
