How are logical operators used in C sharp?
In c#, Logical Operators are useful to perform the logical operation between two operands like AND, OR, and NOT based on our requirements. The Logical Operators will always work with Boolean expressions (true or false) and return Boolean values….C# Logical Operators with Examples.
| Operand | NOT |
|---|---|
| true | false |
| false | true |
How do you write OR in C sharp?
The conditional logical OR operator || , also known as the “short-circuiting” logical OR operator, computes the logical OR of its operands. The result of x || y is true if either x or y evaluates to true . Otherwise, the result is false . If x evaluates to true , y is not evaluated.
What are the data types in C#?
Data types in C# is mainly divided into three categories
| Alias | Type Name | Type |
|---|---|---|
| short | System.Int16 | signed integer |
| Int | System.Int32 | signed integer |
| byte | System.byte | unsigned integer |
| uint | System.UInt32 | unsigned integer |
What are variables in C#?
Variables are containers for storing data values. In C#, there are different types of variables (defined with different keywords), for example: int – stores integers (whole numbers), without decimals, such as 123 or -123. double – stores floating point numbers, with decimals, such as 19.99 or -19.99.
How many datatypes are there in C#?
A data type specifies the type of data that a variable can store such as integer, floating, character etc. There are 3 types of data types in C# language….Value Data Type.
| Data Types | Memory Size | Range |
|---|---|---|
| int | 4 byte | -2,147,483,648 to -2,147,483,647 |
| signed int | 4 byte | -2,147,483,648 to -2,147,483,647 |
What is structure in C#?
In C#, a structure is a value type data type. It helps you to make a single variable hold related data of various data types. The struct keyword is used for creating a structure. Structures are used to represent a record.
What is polymorphism in C#?
Polymorphism and Overriding Methods Polymorphism means “many forms”, and it occurs when we have many classes that are related to each other by inheritance. Like we specified in the previous chapter; Inheritance lets us inherit fields and methods from another class.
