C# How To Add Two Numbers

Add Two Numbers

Learn how to add two numbers in C#:

int x = 5;
int y = 6;
int sum = x + y;
Console.WriteLine(sum); // Print the sum of x + y

Add three numbers

In C#, you can add three (or more) numbers:

// This example demonstrates adding three numbers in C#

// Declaration of variables
int num1 = 10;
int num2 = 20;
int num3 = 30;

// Adding three numbers
int sum = num1 + num2 + num3;

// Outputting the result
Console.WriteLine("The sum of three numbers: " + sum);
        

Explanation of the example:

• In this example, we declare three variables of type int (integer) named num1, num2, and num3.
• Next, we add the values of these three variables using the + operator.
• The result of the addition is stored in the variable sum.
• Finally, we use the Console.WriteLine() method to output the value of the sum variable to the console.

Variations:

• You can change the values of the variables num1, num2 and num3 to any other numbers.
• You can add more numbers to the sum by using the additional operators +.
• You can use variables of other types, such as float (floating-point number) or double (double-precision number).
• This example is just a basic example of adding numbers in C#. There are many other ways to accomplish this task.
