Variables and Data Types
In C#, variables are used to store and manipulate data. Before using a variable, you need to declare its type and assign a value to it.
C# provides various data types to represent different kinds of information. Some of the commonly used data types are:
int(integer): used for storing whole numbers.double(floating-point): used for storing decimal numbers with floating-point precision.string: used for storing text.bool(boolean): used for storing boolean values (trueorfalse).
Here's an example of declaring and initializing variables of different data types:
TEXT/X-CSHARP
1int age = 30;
2string name = "John Doe";
3double salary = 50000.50;
4bool isMarried = false;xxxxxxxxxx39
}using System;namespace DataTypesExample{ class Program { static void Main(string[] args) { // Declaring and Initializing Variables int age = 30; string name = "John Doe"; double salary = 50000.50; bool isMarried = false; // Outputting Variables Console.WriteLine("Name: " + name); Console.WriteLine("Age: " + age); Console.WriteLine("Salary: " + salary); Console.WriteLine("Married: " + isMarried); // Data Type Conversion int num1 = 10; double num2 = 5.5; // Implicit Conversion double result1 = num1; Console.WriteLine("Implicit Conversion: " + result1); // Explicit ConversionOUTPUT
