Perfect forwarding and its use in generic code Perfect forwarding is a C++ technique that allows passing arguments to another function while preserving their value category (lvalue or rvalue) and constness. It is particularly useful in generic code where the type and value category of the arguments may vary. Perfect…

static_cast: Definition: Performs conversions between related types, such as numeric types, pointers, and references, that are known at compile-time. Usage: Used for casting numeric types to other numeric types, upcasting and downcasting in inheritance hierarchies, and converting pointers/references within a class hierarchy. // Casting numeric types int num = 10; double doubleNum…
