Study Notes
Data Types in C#
- Value types are stored on the stack in C#.
- A complex type in C# is a Struct.
Data Types
- The char data type in C# assumes a size of 16 bits (2 bytes) and can hold a single Unicode character.
- The int data type is used to hold numbers in C#.
- The double data type is used to hold numbers with fractional parts in C#.
- The Boolean data type is used to hold true or false values in C# and is typically used for conditional statements and logical operations.
Data Types for Specific Scenarios
- The decimal data type is suitable for storing large, precise decimal values.
- The uint data type is an unsigned integer data type.
Keywords and Operators
- The 'const' keyword is used to declare a constant field or a local whose value is evaluated at compile time.
- The purpose of an operator in C# is to perform operations on variables and values.
- The correct way to assign a value to a variable in C# is using the assignment operator (=).
- A variable can be declared and initialized in a single statement in C# using the assignment operator (=).
Variable Initialization and User Input
- Initializing a variable with a value at the time of declaration in C# makes the code more readable and helps to avoid null reference exceptions.
- The Console.ReadLine() method is used to accept input from the user and store it in a variable in C#.
Value Types and Reference Types
- A value type stores a value directly, whereas a reference type stores a memory address that points to the location of the value.
- Examples of value types include int, bool, and enum, while examples of reference types include classes, arrays, and interfaces.
