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
