More Powerful Lambdas with C++20
Thanks to C++20, lambdas have become more powerful. From the various lambda improvements, template parameters for lambdas are my favorite ones.
Various Template Improvements with C++20
Admittedly, I present in this post a few minor improvements to templates and C++20 in general. Although these improvements may not seem so impressive to you, they make C++20 more consistent and less error-prone when you program generic.
Solving the Static Initialization Order Fiasco with C++20
According to the FAQ of isocpp.org is the static initialization order fiasco “a subtle way to crash your program”. The FAQ continues: The static initialization order problem is a very subtle and commonly misunderstood aspect of C++. “. Today, I write about this very subtle and misunderstood aspect of C++.
Two new Keywords in C++20: consteval and constinit
With C++20, we get two new keywords: consteval and constinit. consteval produces a function executed at compile-time, and constinit guarantees that a variable is initialized at compile-time.
Designated Initializers
Designated initialization is an extension of aggregate initialization and empowers you to directly initialize the members of a class type using their names.
C++20: Optimized Comparison with the Spaceship Operator
In this post, I conclude my miniseries on the three-way comparison operator with a few subtle details. The subtle details include the compiler-generated == and != operators and the interplay of classical comparison operators, and the three-way comparison operator.
C++20: More Details to the Spaceship Operator
The compiler performs cleverly when it generates all six comparison operators. Ultimately, you get intuitive and efficient comparison operators for free. Let me dive into this post into the details of the spaceship operator.
C++20: The Three-Way Comparison Operator
The three-way comparison operator <=> is often just called the spaceship operator. The spaceship operator determines whether A < B, A = B, or A > B for two values, A and B. You can define the spaceship operator, or the compiler can auto-generate it.
C++20: Further Open Questions to Modules
So far, I have written in my last four posts the basics you should know about modules in C++20. Only a few questions about modules are still open. In this post, I address these open questions, such as templates in modules, the linkage of modules, and header units.
