In the C language, the a[i] notation is syntactic sugar for *(a + i). [8] Likewise, the a->x notation is syntactic sugar for accessing members using the dereference operator (*a).x. The using statement in C# ensures that certain objects are disposed of correctly. The compiler expands the statement into a try-finally block. [9]
In reality, extension methods are a form of syntactic sugar that provide the illusion of adding new methods to the existing class outside its definition. The illusion is achieved with the definition of a static method that is callable as if it were an instance method, where the receiver of the call (i.e., the instance) is bound to the first ...
Like with fields, there can be class and instance properties. The underlying methods can be virtual or abstract like any other method. [81] Since C# 3.0 the syntactic sugar of auto-implemented properties is available, [84] where the accessor (getter) and mutator (setter) encapsulate operations on a single attribute of a class.
List comprehension is a syntactic construct available in some programming languages for creating a list based on existing lists. It follows the form of the mathematical set-builder notation (set comprehension) as distinct from the use of map and filter functions.
Operator overloading is syntactic sugar, and is used because it allows programming using notation nearer to the target domain [1] and allows user-defined types a similar level of syntactic support as types built into a language. It is common, for example, in scientific computing, where it allows computing representations of mathematical objects ...
In the programming language Dylan, which is an object-oriented language that supports multimethods and doesn't have a concept of this, sending a message to an object is still kept in the syntax. The two forms below work in the same way; the differences are just syntactic sugar. object.method(param1, param2) and method (object, param1, param2)
This sort of programming construct is very common and a number of programming languages have added some sort of syntactic sugar to address this. For instance, Apple's Swift added the concept of optional chaining in if statements [ 5 ] while Microsoft's C# 6.0 and Visual Basic 14 added the null-conditional operators ?. and ?[ for member access ...
In some programming languages, an assignment statement returns a value, while in others it does not. In most expression-oriented programming languages (for example, C), the assignment statement returns the assigned value, allowing such idioms as x = y = a, in which the assignment statement y = a returns the value of a, which is then assigned to x.
