What Are Variables In C#. Variables are specific names given to locations in the memory for storing and dealing with data. The values of a variable can be changed or reused as many times as possible. Every variable name has a specific type that resolves the size and layout of memory the variable will hold as well as the range of values that variable within your program can hold. Also, programmers can determine which variables can be applied to which type of operation. Types Of C# Variables. The basic types of variables that can be formed in a C# program are: Integral typessbyte, byte, short, ushort, int, uint, long, ulong, and char Floating-point types float and double Decimal types decimal Boolean types true or false values, as assigned Nullable types Nullable data types Define Variables In C#. For implementing variables in a C# program, you have to define them before use. To do this, the syntax is: <data_type> <variable_names> ; Here data_types will be a valid data type (...
C# Programming Structure. The lists of elements that are commonly used in a C# program are: Library invoked by the keyword "using". Declaring namespace using the "namespace" keyword. Declaring a class using the keyword "class". Class members and attributes. The Main() method. Other statements and expressions. Writing comments for user understanding and non-executable statements. Let's look into various parts of the above C# program. /* Comments */ /* Print, some string in C# */, is the comment statement that does not get executed by the compiler and is used for code readers or programmers' understanding. using Here, using keyword is employed for fetching all the associated methods that are within the System namespace. Any C# program can have multiple using statements. namespace Next statement is used for declaring a namespace, which is a collection of classes under a single unit; here "printHelloCsharp". Class Next, you have declared a cl...
