C# 3.0 introduced type inference, allowing the type specifier of a variable declaration to be replaced by the keyword var, if its actual type can be statically determined from the initializer. This reduces repetition, especially for types with multiple generic type-parameters , and adheres more closely to the DRY principle.
C# supports unsigned in addition to the signed integer types. The unsigned types are byte, ushort, uint and ulong for 8, 16, 32 and 64 bit widths, respectively. Unsigned arithmetic operating on the types are supported as well. For example, adding two unsigned integers (uint s) still yields a uint as a result; not a long or signed integer.
The C language provides the four basic arithmetic type specifiers char, int, float and double (as well as the boolean type bool), and the modifiers signed, unsigned, short, and long. The following table lists the permissible combinations in specifying a large set of storage size-specific declarations.
The actual sizes of short int, int, and long int are available as the constants short max int, max int, and long max int etc. ^b Commonly used for characters. ^c The ALGOL 68, C and C++ languages do not specify the exact width of the integer types short , int , long , and ( C99 , C++11 ) long long , so they are implementation-dependent.
A short integer can represent a whole number that may take less storage, while having a smaller range, compared with a standard integer on the same machine. In C , it is denoted by short . It is required to be at least 16 bits, and is often smaller than a standard integer, but this is not required.
C# (/ ˌ s iː ˈ ʃ ɑːr p / see SHARP) [b] is a general-purpose high-level programming language supporting multiple paradigms.C# encompasses static typing, [16]: 4 strong typing, lexically scoped, imperative, declarative, functional, generic, [16]: 22 object-oriented (class-based), and component-oriented programming disciplines.

C accommodates different sizes and signed and unsigned modes for integers by using modifiers such as long, short, signed, unsigned, etc. The exact meaning of the resulting integer type is machine-dependent, what can be guaranteed is that long int is no shorter than int and int is no shorter than short int.
