All of the templates we’ve written so far had a fixed number of parameters, but C++ lets us take a variable number of parameters too. This is like params in C# functions, but for parameters to C++ templates. Today we’ll dig into this feature, which has no C# equivalent, and learn how to write and use templates with any number of parameters.
C++ For C# Developers: Part 28 – Variadic Templates
C++ For C# Developers: Part 27 – Template Deduction and Specialization
Template deduction in C++ is like generic type parameter deduction in C#: it allows us to omit template arguments. Template specialization has no C# equivalent, but enables special-casing of templates based on certain arguments. Today we’ll look at how these features can make our code a lot less noisy and also a lot more efficient.
C++ For C# Developers: Part 26 – Template Parameters
Last time, we started looking at a core feature of C++: templates. We compared and contrasted them to C# generics and saw how they’re applied to classes, functions, lambdas, and even variables. Today we’ll leverage the power of so-called “non-type template parameters” and “template template parameters” to write some really interesting code.
C++ For C# Developers: Part 25 – Intro to Templates
C# generics (List<T>) look a lot like C++ templates (list<T>), but they’re different in many key ways. It’s a big subject, so today we’ll start by looking at some of the most common uses of templates: applying them to classes, functions, members, lambdas, and variables.
C++ For C# Developers: Part 24 – Preprocessor
C# and C++ have similar lists of preprocessor directives like #if, but their features and usage are very different. This is especially the case in C++ with support for “macros” that can replace code. Today we’ll look into everything we can use the preprocessor for in C++ and compare with C#’s preprocessor.
C++ For C# Developers: Part 23 – Compile-Time Programming
The vast majority of the code we write executes at runtime. Today’s article is about the other kind of code, which runs during compilation. C# has very limited support for this. In C++, especially its newer versions, most of the language features are usable at compile-time. Read on to learn how to take advantage of this!
C++ For C# Developers: Part 22 – Lambdas
Both C++ and C# have lambdas, but they have quite a few differences. Today we’ll go into how C++ lambdas work, including all their features and how they compare and contrast with C# lambdas. Read on to learn all the details!
C++ For C# Developers: Part 21 – Casting and RTTI
Now that we’ve seen how types are implicitly converted in C++, we can see how they’re explicitly converted by casting. C++ offers a lot more kinds of casts than C# to control the conversion process. One of them—dynamic_cast—introduces the concept of Run-Time Type Information or RTTI, so we’ll go into that today as well.
C++ For C# Developers: Part 20 – Implicit Type Conversion
We’ve actually seen quite a bit of implicit type conversion so far in the series. We’ve converted integers to floats (float f = 123), arrays to pointers (int* p = a), base type pointers to derived type pointers (D* p = &b), and many more. Today we’ll gather all those casual conversions up into one article that goes over all the rules, including user-defined type conversions.
C++ For C# Developers: Part 19 – Dynamic Allocation
So far, all of the memory our C++ code has allocated has either been global or on the stack. For the many times when the amount of memory isn’t known at compile time, we’ll need dynamic allocation. Today we’ll go over both the basics of new and delete, but also dive into some advanced C++ features such as overloading new and “placement” new.
