Structured Bindings and if-init C++17

Destructure tuples and pairs with structured bindings and use if-init statements.

Destructuring in Modern C++

C++17 added structured bindings — a clean way to unpack tuples, pairs, arrays, and aggregates into individual named variables.

Use auto [a, b, ...] to declare variables bound to the parts of the right-hand value.

std::pair<std::string, int> p = {"Ada", 30};
auto [name, age] = p;
std::cout << name << " is " << age;
