+/*
+	
+	Pre-requisite to solve this problem:
+	In this question, we have to find sum of all even numbers till n. To take sum of all the even numbers, we have to take a variable and initialize it to zero. Let us name this variable as sum. 
+	Following code is used to add 2 to sum variable and update it to the same sum variable:
+	sum = sum + 2 
+	
+	Hint to solve this problem: We will have to loop on even numbers only and add the even numbers to the same sum variable, described above.
