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 24 – 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.
C++ For C# Developers: Part 18 – Exceptions
Like C#, C++ also uses exceptions as one of its main error-handling mechanisms. Today we’ll learn all about them: throwing, catching, their impact on destructors, what happens when they go uncaught, and so much more.
C++ For C# Developers: Part 17 – Namespaces
With structs wrapped up, we can move on to other features of C++. Today we’ll take a look at namespaces. We’ll cover the basics that C# provides, but go so much further and cover a lot of advanced functionality. Read on to learn all about them!
C++ For C# Developers: Part 16 – Struct and Class Wrapup
Today we’ll wrap up structs and classes by discussing a bunch of miscellaneous features: local classes, unions, overloaded assignment operators, and user-defined literals. C# doesn’t have any of these features, but it can emulate some of them. Read on to learn a bunch of new tricks!
C++ For C# Developers: Part 15 – Struct and Class Permissions
Today we’ll cover the last major topic of structs in C++: how we control access to them. We’ll talk about access specifiers like private, the “friendship” concept, and finally get around to the details of const.
