However, the language specification does not state the code generation requirements of the compiler: Typing[ edit ] C supports strongly typed implicit variable declarations with the keyword var, and implicitly typed arrays with c sharp language specification keyword new followed by a collection initializer.
C supports a strict Boolean data typebool. Statements that take conditions, such as while and if, require an expression of c sharp language specification type that implements the true operator, such as the Boolean type.

The only implicit conversions by default are those that are considered safe, such as widening of integers. This is enforced at compile-time, during JITand, in some cases, at runtime. No c sharp language specification conversions c sharp language specification between Booleans and integers, nor between enumeration members and integers except for literal 0, which can be implicitly converted to any enumerated type.
Enumeration members are placed in their own scope. The C language does not allow for global variables or functions.

All methods and members must be declared within classes. Static members of public classes can substitute for global variables and functions. Metaprogramming[ edit ] Metaprogramming via C attributes is part of the language.
Methods and functions[ edit ] Methods in programming c sharp language specification are the members of a class in a project, some methods have signatures and some don't have signatures. Methods can be void or can return something like string, integer, double, decimal, float and bool.

C has support for strongly-typed function pointers via the keyword delegate.
Synchronized ], and has support for mutually-exclusive locks via the keyword lock. Property[ edit ] C provides properties as syntactic sugar for a common pattern in which a pair of methods, accessor getter and mutator setter c sharp language specification operations on a single attribute of a class.
Memory access[ edit ] In Cmemory address pointers can only be used within blocks specifically marked as unsafe, and programs with unsafe code need appropriate permissions to run.
Most object access is done through safe object references, which always either point to a "live" object or have the well-defined null value; it is impossible to obtain a reference to a "dead" object one that has been garbage collectedor to a random block of memory.
An unsafe pointer can point to an instance of a value-type, c sharp language specification, string, or a block of memory allocated on a stack.
Code that is not marked as unsafe can still store and manipulate pointers through the System. C sharp language specification type, but it cannot dereference them. Managed memory cannot be explicitly freed; instead, it is automatically garbage collected.
C sharp language specification collection addresses the problem of memory leaks by freeing the programmer of responsibility for releasing memory that is no longer needed. Exception[ edit ] Checked exceptions are not present in C in contrast to Java.

This has been a conscious decision based on the issues of scalability and versionability. This was a design decision by the language's lead architect to avoid complication and simplify architectural requirements throughout CLI.
When implementing multiple interfaces that contain a method with the same c sharp language specification, C c sharp language specification implementing each method depending on which interface that method is being called through, or, like Java, allows implementing the method once, and have that be the one invocation on a call through any of the class's interfaces.
However, unlike JavaC supports operator overloading.

A developer can query any. Intellisense support, strong filtering capabilities, type safety with compile error checking ability, and brings consistency for querying data over a variety of sources.
Common type system[ edit ] C has a unified type system.
