using System; 
 
class MainClass { 
  public static void Main() { 
    int sum = 0; 
    int[] nums = new int[10]; 
 
    for(int i = 0; i < 10; i++)  
      nums[i] = i; 
 
    foreach(int x in nums) { 
      Console.WriteLine("Value is: " + x); 
      sum += x; 
      if(x == 4) 
         break; // stop the loop when 4 is obtained 
    } 
    Console.WriteLine("Summation of first 5 elements: " + sum); 
  } 
}

Value is: 0
Value is: 1
Value is: 2
Value is: 3
Value is: 4
Summation of first 5 elements: 10
