# Write A C# Program To Find The Largest Of Three Numbers

Do you want to find out the largest of three numbers in C#. In this C# tutorial, I will explain how to write a C# program to find the largest of three numbers.

To find the largest of three numbers in C#, you can use a simple if-else statement to compare the numbers. Start by reading the user input for three numbers, then compare them using nested if-else statements. The program identifies the largest number by checking each number against the others, ultimately displaying the largest one to the user.

## Find The Largest Of Three Numbers in C#

To find the largest of the three numbers, we need to compare them with each other. This can be done using if-else statements in C#. We will compare the first number with the second and third, and then, if necessary, compare the second with the third.

Here is the complete C# program to find the largest of three numbers.

``````using System;

class LargestOfThree
{
static void Main()
{
int num1, num2, num3, largest;

// User inputs for the three numbers
Console.WriteLine("Enter the first number:");

Console.WriteLine("Enter the second number:");

Console.WriteLine("Enter the third number:");

// Comparing numbers to find the largest
if (num1 >= num2 && num1 >= num3)
{
largest = num1;
}
else if (num2 >= num1 && num2 >= num3)
{
largest = num2;
}
else
{
largest = num3;
}

// Displaying the result
Console.WriteLine("The largest number is: " + largest);
}
}
``````

Here is the complete code explanation:

• Namespace and Class Declaration: We start by using the System namespace and declaring a class LargestOfThree.
• Main Method: The Main method is the entry point of a C# application.
• Declaring Variables: We declare four integer variables: num1, num2, num3, and largest.
• User Input: We prompt the user to enter three numbers, reading and converting their input to integers.
• Comparison Logic: Using if-else statements, we compare the numbers to find the largest.
• Displaying the Result: Finally, we print the largest number to the console.

Once you execute the code, it will ask you three numbers to input and display the largest of the three numbers.

## Conclusion

This C# program provides a straightforward solution to determine the largest of three numbers. It’s an excellent example of applying basic programming constructs like variables, user input, conditional statements, and console output in C#.
