break statement

The break statement is used for breaking / stopping a loop mid-execution. It is useful in cases where we want to stop a loop in case some additional condition is met.

Following is an example of the break statement being used in the for-loop:

main


              12345678910111213141516171819
            
using System;

namespace ConsoleApp
{
    internal class Program
    {
        static void Main(string[] args)
        {
			for(int i = 0; i < 10; i++)
			{
			    Console.WriteLine(i);
			    if(i == 5)
			    {
			        break;
			    }
			}
        }
    }
}

The above code outputs i till 5 and then the loop stops. This is because of the additional conditional break we added.

We can also use the break statement in other loops:

main


              12345678910111213141516171819
            
using System;

namespace ConsoleApp
{
    internal class Program
    {
        static void Main(string[] args)
        {
			int i = 0;
			while(true) {
    			Console.WriteLine(i);
    			if(i == 5) {
        			break;
    			}
    			i++;
			}
        }
    }
}

The loop we constructed above works exactly the same as the for-loop we looked at before. The break statement can be used in the do-while loops as well. The break statement is very useful in adding additional conditions to a loop.
