Calculate sum of two numbers using function in C#

Calculate sum of two numbers using function in C#

In this article, we will discuss the concept of Calculate sum of two numbers using function in C#

In this post, we are going to learn how to write a program to  calculate sum of two numbers using function in C# language

Code to find sum of two numbers in C#

Add two numbers using function in C#

In this code, we are going to learn how to write a program to add two numbers with initialized variables using function in C# programming language

Program 1

//Write a program calculate sum of two numbers using function
using System; 
public class Sum_Two_Num_Function { 
    public static int 
    sum_Num(int fNum, int sNum) { //function definition with parameter
        int tot; 
        tot=fNum+sNum; //Find addition of two numbers
        return tot; //return tot to main method
        
    }
        public static void Main() { 
            int fNum=45; 
            int sNum=56; //variable declaration and initialization for numbers
            Console.WriteLine("The sum of {0} and {1} is: {2}: ",fNum,sNum,sum_Num(fNum,sNum)); } }
            //display total of two numbers

When the above code is executed, it produces the following result

The sum of 450 and 560 is: 1010:

 

Add two numbers using function in C# – Entered by user

In this code, we are going to learn how to write a program to add two numbers entered by user using function in C# programming language

Program 2

// Write a program calculate sum of two numbers using function
using System; 
public class Sum_Two_Num_Fun { 
    public static int sum_Num(int num1, int num2) { 
        //Function definition
        int total;//variable for calculate  total of two num
        total=num1+num2; //Calculate total
        return total; //return total
        
    } 
    public static void Main() { 
        Console.Write("Enter number for n1: ");//Ask input from the user 
        int n1=Convert.ToInt32(Console.ReadLine()); //reading the input
        Console.Write("Enter number for n2: "); 
        int n2=Convert.ToInt32(Console.ReadLine()); 
        Console.WriteLine("The sum of {0} and {1} is: {2}: ",n1,n2,sum_Num(n1,n2)); } }
        //Display addition of two numbers

When the above code is executed, it produces the following result

Enter number for n1: 666
Enter number for n2: 777
The sum of 666 and 777 is: 1443:

 

In this code, the user asked to enter two integers and the given integers are stored in variables n1 and n2 respectively.

Then these two numbers are added using the plus(+) operator and the result is stored in the total variable.

Finally the display statement is used to print the addition of this numbers using calling the function
