C++17: Initializers for if & switch statements--Marc Gregoire
Small reminder:
C++17: Initializers for if & switch statements
by Marc Gregoire
From the article:
Two small, but very useful C++17 features are initializers for if and switch statements. These can be used to prevent polluting the enclosing scope with variables that should only be scoped to the if and switch statement. The for statement already supports such initializers since the beginning...
Quick Q: Is (4 > y > 1) a valid statement in C++? How do you evaluate it if so?
Quick A: This is not a valid statement.
Recently on SO:
Is (4 > y > 1) a valid statement in C++? How do you evaluate it if so?
The statement (4 > y > 1) is parsed as this:
((4 > y) > 1)The comparison operators < and > evaluate left-to-right.
The 4 > y returns either 0 or 1 depending on if it's true or not.
Then the result is compared to 1.
In this case, since 0 or 1 is never more than 1, the whole statement will always return false.

Seats are still available for KDAB's 3-day training, February 12th, Berlin:
Modern C++: C++11 / C++14 / C++17
by Don Tait
About the training:
Learn the relevant library and language changes
In this hands-on C++11, C++14 and C++17 training for C++ developers, you'll learn about the language changes and the standard library changes introduced in C++11, C++14 as well as changes from C++17.
During the class, the new standards will be demonstrated aided by many examples and you'll get the opportunity to use them right away in our lab projects.
Course contents:
Important language changes, including:
- C++11/14: lambdas, range based for loops, strongly typed enums,
- C++11/14: constexpr, uniform initialization, move semantics, …
- C++17: improved lambdas, structured bindings, constexpr if, …
- C++11/14: Functional programming, including lambda, bind and function objects
- C++11/14: Template meta programming, including variadic templates and perfect forwarding
- C++11/14: Multithreading (including the C++11 memory model, std::thread, std::async, …)
- C++17: Templates: Fold Expressions, Class template deduction, …
