This is type of binary operator, which means it works with more than one operand. In c#, this can be understood from given code
int a=10,b=5;
a -=b;
Console.WriteLine(a);
In this preceding code, we get 5 as a result. It means subtract operand b from a. This types of expression is equivalent to a=a-b. Lets take an simple example with output
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
int a = 10;
int b = 20;
b -= a;
Console.WriteLine(b);
Console.ReadKey();
}
}
}
int a=10,b=5;
a -=b;
Console.WriteLine(a);
In this preceding code, we get 5 as a result. It means subtract operand b from a. This types of expression is equivalent to a=a-b. Lets take an simple example with output
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
int a = 10;
int b = 20;
b -= a;
Console.WriteLine(b);
Console.ReadKey();
}
}
}
Code generate the following output
