C# Identifiers

All C# variables must be identified with unique names.
These unique names are called identifiers.
Identifiers can be short names (like x and y) or more descriptive names (age, sum, totalVolume).
Note: It is recommended to use descriptive names in order to create understandable and maintainable code.
The general rules for constructing names for variables (unique identifiers) are:
  • Names can contain letters, digits and the underscore character (_)
  • Names must begin with a letter
  • Names should start with a lowercase letter and it cannot contain whitespace
  • Names are case sensitive ("myVar" and "myvar" are different variables)
  • Reserved words (like C# keywords, such as int or double) cannot be used as names

What is C# Booleans ? / C# Booleans क्या है ?

C# Booleans Very often, in programming, you will need a data type that can only have one of two values, like: YES / NO ON / OFF TRUE / FALSE For this, C# has a  bool  data type, which can take the values  true  or  false . Boolean Values A boolean type is declared with the  bool  keyword and can only take the values  true  or  false : Example bool isCSharpFun = true ; bool isFishTasty = false ; Console . WriteLine ( isCSharpFun ) ; // Outputs True Console . WriteLine ( isFishTasty ) ; // Outputs False However, it is more common to return boolean values from boolean expressions, for conditional testing (see below). Boolean Expression A  Boolean expression  is a C# expression that returns a Boolean value:  True  or  False . You can use a comparison operator, such as the  greater than  ( > ) operator to find out if an expression (or a variable) is true: E...
