Introduction
I have used Visual Studio 2012 for debugging purpose. But you can use any version of visul studio as per your availability..
Write a C# program to create a function to swap the values of two integer numbers
using System;
public class functionexcercise
{
public static void interchangenumber(ref int num1, ref int num2)
{
int newnum;
newnum = num1;
num1 = num2;
num2 = newnum;
}
public static void Main()
{
int n1, n2;
Console.Write("Enter two number: ");
n1 = Convert.ToInt32(Console.ReadLine());
n2 = Convert.ToInt32(Console.ReadLine());
interchangenumber(ref n1, ref n2);
Console.WriteLine("After swapping the 1st number is : {0} , and the 2nd number is : {1}", n1, n2);
Console.ReadLine();
}
}Result
