int a, b;
Console.WriteLine("Enter first nos.");
a = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Enter second no.");
b = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("add is :{0}", a + b);
Console.WriteLine("sub is :{0}",a-b);
Console.WriteLine("multiis :{0}",a*b);
Console.WriteLine("devi is :{0}",a/b);
Console.ReadLine();
}
}
}

2) W.A.P to interchange the value of 2 variables without using third variable.
using System;
using System.Linq;
using System.Text;

int a = 6;
int b = 7;
Console.WriteLine("the numbers before swapping a={0} and b={1}",a,b);
a = a + b;
b = a - b;
a = a - b;
Console.WriteLine("the numbers after swapping a={0} and b={1}", a,
b); Console.Read();
}
}
}

3) W.A.P to display array elements & their sum.
using System;
using System.Linq;
using System.Text;
namespace array
{

elements"); for (int i = 0; i < n; i++)
{ Console.WriteLine(num[i]);
}

for (i = 0; i < ar.Length; i++)
{
ar[i] = Convert.ToInt32(Console.ReadLine());
}
Console.WriteLine("Sorted array is: ");
{
{
for (j = i + 1; j < ar.Length; j++)
{
if (ar[i] > ar[j])
{
temp = ar[i]; ar[i] =

}
}
}
