Bitwise AND of Integer
<source lang="csharp">using System; using System.Collections.Generic; using System.Linq; using System.Text;
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Enter an integer:");
int myInt = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Bitwise AND of Integer and 10 = {0}", myInt & 10);
}
}</source>
Comparing integers
<source lang="csharp">using System; using System.Collections.Generic; using System.Linq; using System.Text;
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Enter an integer:");
int myInt = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Integer less than 10? {0}", myInt < 10);
Console.WriteLine("Integer between 0 and 5? {0}",(0 <= myInt) && (myInt <= 5));
}
}</source>
Comparing the Prefix and Postfix Increment Operators
<source lang="csharp">class IncrementExample {
public static void Main()
{
int x;
x = 1;
System.Console.WriteLine("{0}, {1}, {2}", x++, x++, x);
System.Console.WriteLine("{0}, {1}, {2}", ++x, ++x, x);
}
}</source>
integers and arithmetic operators
<source lang="csharp">class MainClass {
public static void Main()
{
System.Console.WriteLine("10 / 3 = " + 10 / 3);
System.Console.WriteLine("10 % 3 = " + 10 % 3);
int intValue1 = 10;
int intValue2 = 3;
System.Console.WriteLine("intValue1 / intValue2 = " + intValue1 / intValue2);
System.Console.WriteLine("intValue1 % intValue2 = " + intValue1 % intValue2);
}
}</source>
10 / 3 = 3 10 % 3 = 1 intValue1 / intValue2 = 3 intValue1 % intValue2 = 1
int variable assignment
<source lang="csharp">using System; class RightAssocApp {
static void Main(string[] args)
{
int a = 1;
int b = 2;
int c = 3;
Console.WriteLine("a={0} b={1} c={2}", a, b, c);
a = b = c;
Console.WriteLine("After "a=b=c": a={0} b={1} c={2}", a, b, c);
}
}</source>
Overflowing an Integer Value
<source lang="csharp">public class Program {
public static void Main()
{
// int.MaxValue equals 2147483647
int n = int.MaxValue;
n = n + 1 ;
System.Console.WriteLine(n);
}
}</source>
Using Binary Operators
<source lang="csharp">class Division {
static void Main()
{
int numerator;
int denominator;
int quotient;
int remainder;
System.Console.Write("Enter the numerator: ");
numerator = int.Parse(System.Console.ReadLine());
System.Console.Write("Enter the denominator: ");
denominator = int.Parse(System.Console.ReadLine());
quotient = numerator / denominator;
remainder = numerator % denominator;
System.Console.WriteLine("{0} / {1} = {2} with remainder {3}",numerator, denominator, quotient, remainder);
}
}</source>
